There's a small ecosystem of physical tools businesses use to capture Google reviews from in-person customers: window stickers, QR codes printed on receipts and table tents, business-card-sized review request cards handed out at checkout. They all promise the same thing — a way to convert the "I should leave a review" intention into actual review action. They don't all work equally well.

Most blog content covering these tools treats them as a uniform set of tactics, listing them out without honest assessment of which ones actually produce results. That's not useful. The reality is that stickers and QR codes work, often spectacularly well when deployed correctly, while traditional review request cards are largely redundant in 2026 — they exist mostly because they existed before QR codes did, and inertia keeps them in some marketing playbooks long after their utility has faded.

This guide is the practical comparison: how each tool actually works, what it does well, what it doesn't, when to deploy each, what most businesses get wrong about deployment, and which combination of tools makes sense for which kinds of businesses. The goal isn't to be diplomatic about "every tool has its place" — it's to help you decide what to actually invest time in versus what to skip.

The Three Tools at a Glance

Before the deep-dive on each, the high-level picture:

Google review stickers — small adhesive decals (typically 3-5 inches) placed at high-visibility customer touchpoints: front doors, checkout counters, restaurant tables, in-vehicle (for ride services), shop windows. Usually feature a Google logo, a five-star graphic, and a QR code linking directly to the business's review form. Cost is essentially nothing per sticker; the deployment is one-time and lasting.

QR codes (without sticker context) — printed QR codes that appear on receipts, table tents, business cards, packaging, signage. Same scanning mechanic as a sticker but applied to varied surfaces and contexts. Often printed dynamically (each receipt) rather than placed once. Cost is functionally zero (just printing).

Review request cards — business-card-sized printed cards handed to customers at checkout, intended to be carried home and acted upon later. Sometimes feature a QR code, sometimes just a URL or instructions to "search for us on Google." Cost includes printing and the small ongoing burden of remembering to hand them out.

Google Review Stickers: What They Are and When They Work

Stickers are the most underused of the three tools and arguably the highest-leverage. A small sticker on a front door, checkout counter, or restaurant table — featuring a Google logo, five stars, and a QR code linking directly to your review form — captures customers in moments of natural waiting or transition.

Why stickers work specifically:

• They're always on. Unlike a verbal ask (which depends on staff remembering) or an automated SMS (which fires after the customer has left), a sticker is visible to every customer for the entire duration of their visit. Some customers notice it on the way in, think about it during the visit, and act on it on the way out.
• They capture "moment-of-waiting" attention. A customer waiting to pay, waiting for a check, waiting for a haircut to be finished — these are precisely the moments when their attention is loose and a small visual cue can prompt action.
• Google has explicitly endorsed stickers as a review tool. The Google for Small Business team has periodically distributed free "Review us on Google" stickers as a small-business support gesture, which signals platform-level support for the format.
• No staff burden. A sticker placed once continues working for years without anyone needing to remember anything.

Where to place stickers (in roughly decreasing order of effectiveness):

• Checkout counter, customer-facing side. Customers paying or waiting to pay see the sticker right at the transactional moment. Highest-conversion placement for most businesses.
• Front door or entry signage. Visible to every customer entering and leaving. Particularly effective for restaurants, cafes, and retail.
• Restaurant tables or booth-mounted holders. Customers have idle moments at tables (waiting for food, waiting for the check) when they'll naturally scan a sticker.
• Restroom or other dwell-time areas. Less common but works in certain contexts (yoga studios, cafes with extended dwell time).
• Service vehicles. For mobile services (HVAC, plumbing, mobile detailing, mobile vet), a sticker on the truck creates exposure during the actual service moment.
• Counter sticker stands. Small acrylic stands holding multiple stickers/QR codes, placed where customers can pick one up (most useful at very high-volume retail).

Sizing matters. Too small (under 2 inches) and customers don't notice it. Too big (over 6 inches) and it looks aggressive or commercial. The 3-5 inch sweet spot is where most successful sticker deployments land.

Design matters. A sticker that looks like a generic marketing badge underperforms a sticker that looks intentional and on-brand. Some businesses commission custom sticker designs that match their visual identity; others use Google's free designs; both can work depending on execution. What doesn't work: cluttered designs with too much text, low-resolution graphics, or stickers that don't actually include a scannable QR code.

The "review us on google sticker" search market. Search volume for "review us on google sticker" and "rate us on google sticker" is meaningful (350+ monthly searches between the two main variants), reflecting the fact that businesses are actively looking for these tools. Most businesses end up either using Google's free stickers, ordering custom prints from Sticker Mule or VistaPrint, or generating them through a review platform that includes sticker design as part of the service.

When stickers don't work:

• Pure delivery or curbside-only businesses. If customers don't physically come into the space, the sticker has nothing to be visible to. Vehicle stickers are the workaround.
• Service businesses where the work happens at the customer's location. A roofer's sticker on the roofer's office wall doesn't help — the customer isn't there. Vehicle stickers and post-job leave-behinds are alternatives.
• B2B contexts. Stickers feel consumer-retail; they look out of place in professional services environments.

QR Codes (Beyond Stickers): What Works and What Doesn't

QR codes are the underlying mechanism that makes stickers work, but they show up in many other contexts beyond stickers. Each context has different effectiveness.

Where QR codes work well:

• On printed receipts. Every paying customer sees the receipt. A QR code in the receipt's footer, with brief text like "Loved your visit? Leave us a Google review" — scan rate runs in the low single digits but applied across hundreds or thousands of receipts per week, the volume adds up. This is one of the most underused review collection surfaces in restaurants and retail.
• On table tents, table cards, or counter cards. Permanent placements that customers see during dwell time. Effective in restaurants, salons, waiting rooms, dental offices. The sticker section above covers placement principles.
• On business cards. A small QR code on the back of business cards that staff hand out. Works well for service businesses where the customer relationship is more personal (real estate, financial services, contractors).
• On packaging or in-shipping inserts. For e-commerce or product retail, a QR code on the package or on a small thank-you card inside drives review conversion from delivered orders.
• On vehicle wraps. For mobile services, QR codes on the vehicle convert at the scene of the service or as exposure to nearby observers.
• On invoices and quotes for service businesses. A QR code at the bottom of every invoice catches customers at the moment of payment review.

Where QR codes don't work as well as their reputation suggests:

• Buried in tiny type at the bottom of receipts. If the QR code is so small or low-quality that it doesn't scan reliably, it might as well not be there. Test from multiple devices before deploying.
• On in-store displays without context. A QR code with no explanation — no "leave us a review" prompt — doesn't motivate action. The QR code itself isn't enough; the brief text accompanying it does the work.
• On websites and emails (where you should use a direct link). People reading a website or email on their phone don't pull out a QR scanner — they just want to tap a link. QR codes on digital surfaces are friction; clickable links are the right answer.
• In low-light environments. Bars, dim restaurants, evening events — QR codes scan poorly when the customer's phone camera struggles with the image. Use bright, high-contrast QR designs in these contexts.
• As the only review collection method. A business relying purely on QR codes captures a fraction of what a business deploying QR codes alongside automated SMS captures. The two approaches address different customer moments and complement each other.

The technical fundamentals worth getting right:

• The QR code must link directly to your Google review form. Not to your website, not to your Google Business Profile listing — directly to the review submission interface. The cleanest URL formats are the g.page format from your Google Business Profile dashboard or a Place ID-based URL.
• The QR code must be high enough resolution to scan reliably. Small printed QR codes on thermal-printer receipts are particularly prone to scanning issues. Test before deploying widely.
• Consider source tracking. Some review request tools generate location-specific or surface-specific QR codes, letting you see whether your receipts, table tents, or door stickers are actually generating reviews. This data informs where to invest more.

Review Request Cards: Why They've Largely Stopped Working

Cards are the third leg of the physical-tools stool, and they're the weakest in 2026. Not because they don't generate any reviews — they do — but because the customer behavior they depend on doesn't match how customers actually behave today.

The theory of cards: Customer pays, gets a small card with a request to leave a Google review, takes the card home, remembers it later, sits down at a computer or phone, types in the URL or searches for the business, and leaves a review.

The reality: Each step in that chain has 30-50% drop-off. The customer puts the card in their pocket and forgets. Or they remember a week later but the card is somewhere they can't find. Or they find it but the URL is too long to type or the search doesn't surface the right business. End-to-end conversion from cards is typically a tiny fraction of conversion from stickers, QR codes on receipts, or automated SMS.

Why cards persist anyway:

• They predate QR codes. Many marketing playbooks include cards because they were the standard tool ten years ago. They've been left in place even though the tools that replaced them are dramatically more effective.
• They feel like a marketing artifact. Some business owners associate tangible cards with professionalism. The intuition isn't wrong; it's just that the same professionalism is now better signaled with a clean sticker design or a well-formatted receipt QR code.
• They're cheap and someone made them once. Once a business has a stack of 1,000 review request cards printed, they tend to use them up out of sunk-cost reasoning rather than evaluating effectiveness.

When cards still might make sense:

• High-touch professional services. Real estate agents, financial advisors, attorneys — where handing the client a tangible card at closing or final meeting feels appropriate to the relationship. Even here, the card is mostly ceremonial; the actual review request comes via SMS or email.
• As QR-code-bearing cards (essentially identical to stickers placed on a card). A "card" with a QR code is functionally a portable sticker. The QR code does the work, not the card format.
• Non-digital customer segments. Older customers without smartphones, or in markets where smartphone penetration is lower. Even here, the conversion math is challenging.

The honest framing: for most local businesses, cards are a tool whose time has passed. The money and attention spent on cards is better deployed elsewhere — better stickers, well-placed QR codes on receipts and signage, automated SMS infrastructure for customers whose contact info you've captured.

What Most Businesses Get Wrong About Physical Review Tools

Across stickers, QR codes, and cards, a few deployment mistakes show up over and over:

Hiding the tool. A QR code in 6-point type at the bottom of a receipt. A sticker on the back of a register where customers can't see it. A card slipped into a bag and forgotten. The single most common mistake is treating physical review tools as tasteful decorations rather than visible prompts. Visibility is the whole point.

Skipping the brief text. A QR code without context — no "leave us a Google review" prompt — converts a fraction of what a QR code with a clear prompt converts. The prompt does the motivational work; the QR code does the technical work.

Using broken or unreliable QR codes. A QR code that doesn't scan reliably from typical mobile devices is worse than no QR code, because it generates a small but real frustration moment with customers who try and fail. Test every QR code from multiple devices, multiple operating systems, and in the actual lighting conditions where it'll be used.

Linking to the wrong destination. The QR code should land the customer on your Google review form, not on your homepage, not on your Google Business Profile listing, not on a search results page. One additional step between the customer and the review form loses 30-50% of intended completions.

Overcrowding the design. Stickers and cards with too much text, multiple CTAs, or competing visual elements convert worse than clean, single-purpose designs. The customer should see one thing — "leave us a Google review" — and one action — "scan this code."

No source tracking. Without unique QR codes for each placement (receipt vs. door sticker vs. table tent), you can't tell which surfaces are actually generating reviews. Most review request tools support source-specific QR code generation; use it.

Treating physical tools as the entire program. Physical tools are a layer of review collection, not the whole thing. A business that deploys excellent stickers and QR codes but has no automated SMS infrastructure for customers whose contact info they capture is leaving most available reviews on the table. The two approaches complement each other; neither is sufficient alone.

Letting deployments go stale. Stickers fade, peel, or get covered by other signage over time. QR code printers misalign. Card stacks get hidden under counter clutter. Audit deployments quarterly and refresh what's degraded.

Which Tools Make Sense for Which Kinds of Businesses

Different business types benefit from different combinations.

Retail (clothing, books, gifts, specialty stores). Stickers at the checkout counter and front door. QR codes on receipts. Skip cards.

Restaurants and cafes. Stickers at the host stand and on table tents. QR codes prominently on every receipt. Skip cards.

Quick service and counter-service food. Stickers at the order counter and pickup window. QR codes on receipts and packaging. Skip cards.

Salons, spas, and personal care. Stickers at checkout. QR codes on receipts. Possibly cards as a portable QR-code surface for customers who want to take it home, though this is largely redundant.

Home services (HVAC, plumbing, electrical, contractors). Vehicle stickers on service trucks. QR codes on invoices, quotes, and post-job leave-behinds. Cards as a portable QR-code surface that techs can leave with customers — this is one context where cards still earn their keep, because the customer interaction happens at the customer's home and there's no register or counter to place a sticker on.

Auto services (repair, detailing, body shops, dealerships). Stickers in the customer waiting area. QR codes on invoices and receipts. Vehicle stickers if the shop has a service fleet.

Healthcare practices. Stickers in waiting rooms and at checkout. QR codes on visit summaries and discharge paperwork. Skip cards. Be HIPAA-aware about what content goes on the surfaces.

Professional services (real estate, financial advisors, attorneys, accountants). Cards (with QR codes) at closing, final meetings, and major milestones. Stickers in office reception areas. QR codes in email signatures and on business cards.

Mobile services (mobile detailing, pet grooming, mobile vet, in-home services). Vehicle stickers as the primary surface. QR codes on invoices and any leave-behind paperwork.

E-commerce and product retail. QR codes on packaging inserts. Skip stickers (no physical premises). Skip cards.

B2B services. QR codes on business cards. Stickers in office reception. The whole approach skews toward digital channels (SMS, email) rather than physical tools, because B2B relationships are typically higher-touch and longer-arc.

Putting It All Together

For most local businesses, the practical answer to "which physical review tool should I use?" is: stickers and QR codes, in combination, with cards skipped.

Specifically, a typical local business benefits from:

• One or two stickers at high-visibility customer touchpoints (checkout counter, front door)
• QR codes on receipts if you produce printed receipts
• QR codes on signage or table tents if your customer dwell time is more than a few minutes
• Source tracking to monitor which surfaces actually generate reviews
• Automated SMS or email infrastructure for customers whose contact info you capture (this isn't a physical tool, but it's the layer that physical tools complement)

Cards earn their keep in a few specific contexts (home services, professional services with major milestones), but for most businesses they're a legacy tool that's been replaced by better alternatives.

The strategic mindset that produces results: physical review tools are leverage that costs essentially nothing per use and runs continuously without staff effort once deployed. The deployment quality matters far more than the choice between sticker vs. QR code vs. card — a thoughtfully placed sticker outperforms three poorly-placed QR codes; a well-designed receipt QR code outperforms a fancy custom sticker design that's hidden behind the register.

Most businesses underinvest in deployment quality and overinvest in tool variety. The fix is the opposite: pick a small number of high-leverage placements, design them well, test them thoroughly, track which ones actually generate reviews, and refresh them when they degrade.
