A regular leans on the counter and asks where her stamps went. You open the shoebox. Half the cards are gone, one is stained, and hers isn't in the stack. She says eight punches. You remember six. Neither of you can prove it.
Most loyalty tools don't differ much in the rewards they promise. They differ in how the customer gets in. Some want a separate download. Some put a pass in Apple Wallet or Google Wallet, which is already on the phone. Some only work through a store account the person already has.
This roundup sorts eight options by that access path and by shop type, not by feature count. I'll flag limits, public pricing, and who each one fits. A café owner, a salon, and a Shopify seller should not pick the same product.
For a micro-merchant, the winner is usually the program a customer can join in under a minute, with no extra app and no extra hardware.
Phones were already the back office a decade ago. Intuit's 2016 Appification of Small Business study surveyed 2,000 owners and managers and found that 68% of small businesses used mobile or web-based apps to run operations, while 66% used a smartphone. Among businesses already using apps, 82% relied on between one and six applications, and about two in five believed there were too many apps to choose from. Keep the stack small.

1. Loyal Customer
A wallet pass is the whole pitch. The customer keeps the card in Apple Wallet or Google Wallet, and the merchant runs the program from a phone.

Joining runs through the business's QR code or unique link: the customer opens a branded page, verifies a phone number with a one-time code, and saves the card to Apple Wallet or Google Wallet. No customer app is part of the flow. Loyal Customer lists coffee bars, restaurants, hair salons, retail shops, bakeries, gyms, spas, supermarkets, and Instagram or WhatsApp sellers as the businesses it serves. Setup asks for colors, a stamp icon, and a reward, recommends stamps or points, shows the wallet card before launch, and saves progress across devices. Building the card takes a few minutes; approval usually lands within 1–2 hours by email and in-app notification.
At checkout, the scanner in the Loyal Customer app adds or redeems in one tap on any smartphone, with no POS or extra hardware. When a code will not scan, the customer can be found by name, email, or phone. I'd shortlist it where join speed matters more than deep register automation.
Price, trial, and the hard limits
For capacity, the plan includes up to 100 customer slots, a custom onboarding page, branded card design, a choice of points or stamp cards, unlimited offers, discounts and stamp rewards, Apple and Google Wallet integration, QR scanning at checkout, and email support. A free plan gives 15 customer slots, no credit card, and the core features after signup and business registration. The 7-day free trial starts when the program launches, and the plan can be cancelled at any time; setup and preview stay free before that.
The hard limit is workflow. Every stamp or point still needs a staff tap or a customer lookup at the till, so a counter that wants loyalty to fire inside a POS ecosystem with no second action will feel the extra step.
If a regular has to create an account before the first stamp, you've already lost the Tuesday crowd.
- Cafés and salons: a flat visit maps cleanly to a stamp.
- Uneven baskets: points track spend better than one stamp per trip.
- Skip it if: loyalty has to post itself from Square or Shopify with no second tap.
2. Square Loyalty
If the sale already happens in Square, loyalty shouldn't be a second brain.
Customers earn points from spending, visits, or selected items, then redeem a discount or a free item. Enrollment, balance texts, and the customer record sit next to the sale, in person and online. That's the product. Not a prettier paper card.
A 2025 U.S. Chamber of Commerce study of 3,870 U.S. small businesses with fewer than 250 employees found that 58% use four or more technology platforms, and businesses using six or more were nearly one-third of small businesses. I wouldn't add another system if Square already runs the counter. For card styles that don't depend on one register brand, see this look at rewards cards.
What you give up
You're inside Square's account, not handing over a pass the customer keeps outside that ecosystem. Setup runs through Square Dashboard, not only from a phone in your apron. Cost and which rewards you can turn on depend on your Square plan and the current offer. A shop that doesn't use Square POS or Square online shouldn't start here just to get loyalty.
Best fit: cafés and retailers already selling on Square. Weak fit: a WhatsApp baker who only needs stamps and has no Square account.
Details sit on Square Loyalty.
3. Loopy Loyalty
Say a three-chair salon still punches a paper card that lives in a coat pocket. Loopy is built for that replacement, and not much else.

Customers add a digital stamp card to Apple Wallet or Google Wallet from a QR code or a link. Staff stamp from an app. You get card designs, reporting, and push messages. Higher plans raise the caps on designs, staff users, and locations. There's a 15-day trial and it doesn't ask for a credit card.
Where the simple model bends
Stamps are the job. If you need spend-based points, item rules, or a membership, this isn't the toolkit. Allowances for locations and staff change by plan, so a second shop can jump you a tier. Wallet behavior also isn't identical on Apple and Google phones. Test both before you print the QR for the mirror.
- Join path: wallet pass, no loyalty app for the customer.
- Staff path: a stamping app, which is one more login for the team.
- Trial: 15 days, no card on file.
I'd use it for a single-location visit reward and stop there. Pricing and plan caps are on Loopy Loyalty.
4. Loyalzoo
Some shops don't only want a free coffee. They want a paid membership on top of points or stamps.

Loyalzoo covers points or stamps, Apple Wallet and Google Wallet passes, promo messages, and birthday campaigns. It also sells memberships and subscriptions with recurring payments. That's a different product from a digital punch card. A gym or a salon with a monthly plan can justify it. A bakery doing one stamp per loaf usually can't.
Public plans describe a wide set of marketing and reward tools. Some messages run on credits or sit behind a plan limit. Multi-location work and custom integrations tend to need a higher tier. Expect a higher bill than a basic stamp service.
A membership tool that also does stamps is not the same as a stamp tool that stays out of the way.
Check current tiers on Loyalzoo before you promise clients a paid plan you haven't priced.
5. Stamp Me
The card can be digital and still hide behind an app icon the customer never opens.

Stamp Me is a visit-based stamp service. Collection can run through stamp codes, and relevant plans add push notes, birthday campaigns, and re-engagement. You can run more than one program. Extra published programs can carry a one-time charge. Zapier is there if you want to push events into other tools. A 30-day trial lets you run a live card before you pay.
The extra step
Customers may need the Stamp Me app. That's a real difference from a wallet-only pass. Every person who won't install it is a regular you don't have. Some engagement tools sit on higher-priced plans, so the trial screen and the paid screen aren't the same product. If you only need a free-to-try stamp card with less app friction, compare approaches in this guide to a digital stamp card.
- Use it when: repeat visits are the whole offer and your crowd will install one app.
- Skip it when: join time has to stay under a minute at a busy counter.
Plan limits are listed on Stamp Me.
6. Magic Stamp
No POS required is the honest selling point. Wallet-only is not.
Magic Stamp runs digital stamp cards and rewards, with QR options and a physical stamp device. Listed bundles can add vouchers and ordering. You can test loyalty without ripping out the till you already have. That matters for a takeaway that isn't ready to change checkout just to track a free meal.
Customers use the Magic Stamp app, not only Apple Wallet or Google Wallet. Custom card design can cost extra. Features and prices change by region and by bundle, so a quote you saw for one country may not match yours. Public pricing is shown by site and plan, which is better than a "contact us" wall, but you still have to read the bundle, not the headline.
An app for small business loyalty only works if the Tuesday regular will open it. If your customers already refuse extra downloads, don't pick a tool whose card lives in someone else's app.
- Good: loyalty without a POS project, plus light ordering or vouchers.
- Bad: you wanted the pass to sit next to boarding passes and tickets.

7. Piggy
Piggy is a loyalty and engagement platform built around configurable rules, digital rewards, and campaigns. It covers businesses at different sizes, and separate Shopify integration plans are listed. The provider advertises a free start or trial. Core pricing sits above most lightweight stamp tools, and the wider feature set takes more setup and more weekly attention. Confirm what each tier includes before you migrate a customer list.
The OECD's 2024 D4SME survey found that 72% of surveyed small and medium-sized enterprises used data gathered and analyzed digitally to support strategic decisions. Piggy is built for businesses that already run cloud, mobile, and e-commerce tools together. That is a stretch for a single-counter café.
Who should bother
A growing retailer or a multi-site operator that wants campaigns and customer data in one place can use the extra weight. A micro-merchant who needs stamps this month will feel the admin. I'd only move here after a simpler program is already redeeming.
Tiers are on Piggy pricing.

8. Smile.io
A Shopify seller doesn't need a stamp card on the counter. They need points that follow the order.

Smile.io is built around Shopify. Points and referrals are the core. Higher plans add VIP-style perks, more integrations, and extra reward types. It also supports Shopify POS, so online points and in-person activity can share a customer. A free plan exists for smaller stores, with monthly order caps and feature limits. Read those caps. A quiet store fits. A store that suddenly gets a rush can outgrow the free tier in a month.
Native wallet stamp cards aren't the job. A salon or a gym that never touches Shopify will fight the product. If you're comparing no-cost ways to start any loyalty software, including options outside Shopify, start with customer loyalty program software and then come back to Smile only if the store is already there.
- Use it when: the shop is Shopify, online or with Shopify POS.
- Don't use it when: the "store" is a chair, a class, or a WhatsApp chat.
Current plans are on Smile.io.

Pick the Program Your Customers Will Actually Use This Month
Don't rank these eight. Answer three questions about your own counter.
Do customers already live in a wallet, or will they refuse another app? Is the ticket steady enough for stamps, or does spend swing enough that you need points? Do you already run Square or Shopify, so loyalty has to connect there?
A café, salon, or micro-merchant without a POS usually wins with a wallet pass and a fast launch. A Square shop should stay in Square. A Shopify store should stay in Smile.io. A gym selling memberships can look at Loyalzoo. Everyone else is paying for admin they won't use.
Security is part of the choice, not a footnote. The OECD's 2025 SME survey found that reported digital-security breaches doubled to 32%, while 83% of non-users were concerned about data privacy, compared with 70% of users. Collect a phone number and a name if you need them to run stamps or points. Skip birth dates, precise location, and contact-list access unless a reward needs them.
Test one real group before you commit. Loyal Customer includes a free plan with 15 customer slots and no credit card, plus a 7-day trial that starts at launch and can be cancelled at any time. Run it on this week's regulars. If they don't add the pass, a bigger platform won't fix that.
- Confirm the access path: wallet pass, your app, or their store account.
- Lock the program type: stamps for steady visits, points for uneven spend.
- Verify the price after the trial: slots, locations, and extra card fees.
- Set a review date: two weeks out, count redemptions, not sign-ups.
We run a phone-based loyalty program for cafés, salons, shops, and chat sellers, with stamp cards or points on Apple Wallet and Google Wallet and no customer app to install. If the shoebox is still how you track regulars, start with a pass your customers already know how to open. Visit Loyal Customer and set up a card you can preview before you launch.
