Is there a free digital stamp card for a small shop that needs no app download?
Yes. As of October 2026, two tools offer a digital stamp card with a free plan, no customer limit and no app for customers to download: KANJIN (kanjin.app) and FaveCard. BonusQR also lists a free plan with unlimited customers, but we did not check how its customers join. KANJIN's free plan also includes 20 Google review requests a month, one email a month to up to 150 regulars and a free Square connection, and its paid plan is $39 per location a month or $390 a year.
Most other stamp card tools have no free plan. They offer a trial of 7 to 30 days and then charge $25 to $79 a month. Several need the customer to download an app.
We make KANJIN, a digital stamp card and back office for small walk-in shops. So we follow two rules in this post. Every price and trial comes from the vendor's own page or a named source, with a link and the date we read it. And where another tool is better than ours, we say so.
Updated 22 October 2026. First published 12 September 2026. Vendors change prices often, so the date we read each page is in the table.
The comparison table, with sources
"Free plan" means a plan with no end date. A free trial is not a free plan. "Not checked" means no vendor page we could read answers it. Ask the vendor before you decide.

The full dataset, with every source and check date, is on our research page: loyalty and review software pricing for small shops (2026). Corrections go to roy@kanjin.app.
Brewstamp, Cuppacard, Passtastic and BaristaCard also sell digital stamp cards. We have not read their pricing pages, so we do not quote them. Ask them the four questions below.
Four questions to ask before you pick
- What do I pay each month after the trial? A free trial ends. A free plan does not.
- How does a customer join? An app they download, a wallet pass, a phone number, a QR code or a POS account?
- Is there a contract, and does it renew on its own?
- Can I download my customer list if I leave? Ask for the export before you sign, not after.
Tool by tool, and where each one is better
KANJIN (kanjin.app), ours
KANJIN is a free digital stamp card and back office for cafes, bakeries, bubble tea shops, barbers, salons, nail studios and small shops. A customer gives their phone number at the counter, and staff press one button on a tablet or phone. That is the stamp. Or the customer scans the QR code on the printed Counter poster and joins from their own phone. Nothing to download, no card to carry.
The free plan has no time limit and no customer limit, and it needs no card. It includes 20 Google review requests a month by email, sent one hour after a stamp, by Google's rules: everyone is asked the same way and nothing is offered for a review. It also includes one email a month to up to 150 regulars, a Daily ledger of sales and costs, Break-even and Profit by item, free staff logins, a report of your regulars and who is slipping away, and a CSV download of your whole customer list with one press in Settings.
Using Square? Connect it free in Settings. A customer already on the card who pays with Square is stamped, and the profit analysis reads your Square sales. Square sales do not go into the Daily ledger.
The paid plan is $39 per location a month, or $390 a year, and the first 30 days are free. It adds review requests with no monthly cap, two emails a week to up to 1,000 customers, a slow-day email, a rainy-day email, a "we miss you" email when a regular stops coming, birthday treats, bring-a-friend stamps, your logo on the card, and local creator discovery.
The free plan has no time limit and nothing is charged until you start the paid plan yourself. It is $39 a month, or $390 a year, per shop, and the first 30 days are free.
Where others are better: KANJIN has no Apple or Google Wallet pass and sends no text messages. With every POS except Square, the stamp is a second step at the counter. KANJIN email works in every country.
FaveCard
As of 12 October 2026, FaveCard has a free plan with no end date and no limit on customers, for 1 active card and 1 location. The card opens in the customer's web browser, so there is no app. New accounts get the paid tools until their first 30 customers. Pro is $19 a month and adds Apple and Google Wallet passes. Business is $39 a month and adds a CSV export, win-back and birthday messages, and Google review requests.
Where it is better: the card can live in the customer's Wallet from $19 a month. KANJIN has no Wallet pass. What to check: we found no page that says it connects to a POS.
BonusQR
As of 10 October 2026, BonusQR offered a free plan marked "0€ / forever" with unlimited customers and visits. The Basic plan is €19 a month. Its page says "free trial" without a length. The page did not load when we tried again on 22 October, so we could not re-read it. We did not check how customers join, so ask before you decide.
Where it is better: it lists a free plan with no customer limit, on the vendor's own word, and its prices are in euros.
Loop Fans
As of 22 October 2026, Loop Fans has a free plan capped at 20 members, with no broadcast email. Grow is $29 a month for 100 members and 1,000 emails a month. We did not check how customers join.
Where it is better: shared programs across several businesses. What to check: the free plan stops at 20 members, and it offers rewards for reviews, which Google's review policy does not allow.
Loyverse
Loyverse is a free point-of-sale app, and its loyalty program is part of the free app (read 22 September 2026). Add-ons such as sales history and employee management cost from $5 a month. It replaces your register rather than sitting next to it.
Where it is better: a free POS and a free stamp card in one app, with the stamp at the register.
LINE Official Account (Taiwan)
If your shop is in Taiwan, LINE Official Account has a free Light plan with 200 messages a month and a built-in shop card (read 22 September 2026). To use the card, a customer adds your shop as a LINE friend, per LINE's guide. The Medium plan is NT$800 a month, and it rises to NT$1,000 on 1 November 2026, per LINE's price plan page.
Where it is better: most Taiwan customers already have LINE, so there is no new app. What to check: whether the shop card is included on the free plan, and how you export your friend list.
Loopy Loyalty
As of 10 October 2026, Loopy Loyalty Starter is $25 a month with a 15-day trial and no free plan. The card is a pass in the customer's Apple or Google Wallet. No app to download. CSV export is on the Ultimate plan at $95 a month.
Where it is better: the Wallet pass is the best answer to "my customers will not install an app" among the paid tools, and push messages to the lock screen are free.
Stamp Me
As of 12 October 2026, Stamp Me Lite is $49 a month with a 30-day trial and no free plan. Customers who join on their own use the Stamp Me app. Its help center says the shop can add a customer from its console instead, but that customer cannot see their own stamps. Text messages are on Pro ($79) and Elite ($199, shown with a $100 limited-time price on 22 October).
Where it is better: the longest trial here, a tap device for fast stamps, and texts on Pro. What to check: section 4.2 of its merchant terms says Stamp Me keeps ownership of its members' contact details.
Loyalzoo
As of 12 October 2026, Loyalzoo Grow is $77 a month with a 7-day trial. It runs inside eight POS brands, including Square and Clover, per its integrations page. Customers can also use a branded web app.
Where it is better: if you already ring up sales on one of those eight POS systems, the stamp happens at the register with no extra step. The trade is the price.
Square Loyalty
As of 12 October 2026, Square Loyalty comes with Square Plus at $49 per location a month, per Square's own announcement. Square offers a 30-day loyalty trial with no locked-in contract. Customers join with a phone number at the register, online or on an invoice.
Where it is better: the stamp happens at the register, and Plus sends texts. If you already pay for Square Plus, loyalty costs you nothing extra. If you are on Square Free, read Square Loyalty alternatives in 2026.
Kangaroo Rewards, SumUp Connect and TapMango
These are paid suites for shops with volume. Kangaroo Rewards Core is $79 a month. SumUp Connect Plus is $269 a month, and SumUp lists a money-back guarantee. TapMango shows no price on its own page; one third-party report puts bills at $350 to $400 a month on a 12-month contract, so treat that as unverified. All three were read on 22 September 2026, and the Capterra pages behind the TapMango and SumUp Connect notes were not re-read on 22 October.
Where they are better: referrals and contests (Kangaroo), monthly AI promotions (SumUp Connect), and a branded app with SMS and a kiosk (TapMango).
How to choose
- You want a free card with no customer limit and no app. KANJIN or FaveCard. BonusQR also lists a free plan, but we did not check how its customers join. There is nothing to cancel.
- You want a free card plus Google review requests and a daily ledger. KANJIN. The other free plans put review requests on a paid tier or do not list them.
- You want the card in the customer's phone wallet. Loopy Loyalty at $25, or FaveCard Pro at $19.
- You ring up sales on Square. Square Loyalty if you pay for Plus. If not, KANJIN connects to Square free, and Loyalzoo runs inside it for $77.
- You want a free POS and a free card in one. Loyverse.
- You are in Taiwan. Start with LINE, because your customers already have it. KANJIN's stamp card and emails also work in Taiwan.
Frequently asked questions
Is there a digital stamp card that is free forever? Yes. As of October 2026, KANJIN (kanjin.app) and FaveCard each have a free plan with no end date and no customer limit. BonusQR also lists one, per its page last read on 10 October. Loop Fans and Loyverse also have free plans: Loop Fans stops at 20 members, and Loyverse is a free POS with loyalty inside it.
Do customers have to download an app for a digital stamp card? Not with most tools in this list. KANJIN uses the customer's phone number or a QR code, FaveCard opens in the browser, and Loopy Loyalty uses a Wallet pass. Stamp Me customers who join on their own use the Stamp Me app, and LINE's shop card needs the LINE app.
Which free stamp card works with Square? KANJIN's stamp card is free, and Square can be connected free in Settings. A customer already on the card is stamped when they pay with Square. We found no FaveCard or BonusQR page that says they connect to Square, and Loyalzoo runs inside Square from $77 a month.
Can I take my customer list with me if I leave? Ask each vendor before you sign. KANJIN exports on every plan with one press in Settings. FaveCard's CSV export is on Business ($39 a month), and Loopy Loyalty's is on Ultimate ($95 a month), both read in October 2026. Square staff say in the Square community that loyalty points cannot be exported as a CSV.
How many stamps should a reward take? Match the card to how often a regular visits. A coffee shop card of 10 fills in 2 to 3 weeks for a daily regular, and a barber card of 5 or 6 cuts fits a visit every 45 days. The free Loyalty card calculator shows what the reward costs you per visit.
Where KANJIN helps
Work out what one extra visit is worth to you with the free Break-even calculator. Then divide any monthly fee by that number. That is how many extra visits a tool must bring in each month to pay for itself. A free stamp card needs none.
To test a card this week, print one with the free Stamp card maker, or open a free KANJIN account. The stamp card is free, with no time limit, no customer limit and no credit card, and your customers download nothing.
