A stamp card your regulars keep on their phone

Tell your own AI, like Claude or ChatGPT, what you want: “9 stamps, the 10th coffee free.” Customers show a code, your staff scan it with their phone’s camera and tap ✓, and the stamp is added.

Scan, tap ✓, done

The whole thing takes a few seconds at the counter. Nothing to install, for your customers or your staff.

  1. Your customer taps Show my code

    A QR code appears on their phone, on your site. It changes every 40 seconds and works for one scan.

  2. Your staff point their camera at it

    The phone’s normal camera app opens the code. Staff are signed in to Page Lemon, so there’s nothing else to install.

  3. They check, and tap ✓

    The screen shows the customer’s name and the stamp. Nothing is added until staff tap ✓ Confirm. Wrong person? Tap ✕ Cancel.

  4. The stamp lands on their card

    Their card updates on its own, and the code disappears: it works only once.

  5. The reward is ready

    At 9 of 9 their card says “Free coffee: 1 ready”. On the next scan, staff choose Free coffee and tap ✓.

Example: Maya opens Oat Café’s site on her phone. Her card shows 6 of 9 coffee stamps, and she taps Show my code. A barista points his phone’s camera at the code and opens it. His screen shows “Maya, +1 Coffee stamp, 6 of 9” with a big Confirm button and a big Cancel button. He taps Confirm. Maya’s card now shows 7 of 9, and her code has gone. Two visits later her card shows 9 of 9 and “Free coffee: 1 ready”.

Set it up in one sentence

You don’t fill in settings. You tell your own AI what you want, and it builds the card into your site, in your colours. Works with Claude, ChatGPT and other AI chats that connect to Page Lemon.

  1. Add a loyalty card to my café’s site on PageLemon.com: 9 stamps, and the 10th coffee is free

    Your AI builds the sign-in, the card and the code in your site’s design.

  2. Use template pagelemon.com/tp/Loyalty for my café’s stamp card

    Starts from the Loyalty template, with the stamps and the reward already set up.

  3. Make the reward a free pastry after 8 stamps

    Change it whenever you like. Every customer’s card shows the new rule.

Try it live

Kettle & Crane is a made-up coffee shop with a real stamp card on Page Lemon. On a real site, customers sign in with their email and a 6-digit code. Here you’re the customer, then the barista.

  1. Sign in (no code needed)
  2. Get your card
  3. Tap Simulate staff scan and play the barista

This is a real demo site. Nothing is emailed; it resets every night.

Open the demo card

Or see the whole sample, from the card to the staff page: Pennywort Bakery.

Your staff scan. That’s all they can do.

Give your staff only the Scan users permission. On App and up, add them to a Loyalty Manager group: they can scan codes to give stamps and rewards, and nothing else. They can’t see your customer list, your emails or your site settings.

  • A wrong tap? The same person can Undo it within 10 seconds.
  • Every stamp and reward is logged with who gave it, and your Dashboard shows the last 100.
  • If you like, staff note something on the confirm screen, like the service, the stylist or what they bought. You choose the fields. Staff can write them but never read them back.

Example: at a hair salon, the stylist scans Ana’s code. The confirm screen shows “Ana, +1 Visit, 4 of 5”, a Service field with “Cut and blow-dry”, a Stylist field with “Jo”, and the big Confirm and Cancel buttons. After Confirm, a note says the visit was added, with Undo.

No cheating, no arguments

Page Lemon runs the rules, so you don’t have to police them at the counter.

  • A screenshot won’t work

    Each code works for one scan and stops working within a minute. It holds no email or name.

  • One stamp a day

    Each customer gets one stamp a day unless you choose more. The day runs midnight to midnight in your site’s time zone.

  • A record of everything

    Every stamp and reward is logged with the customer, the time and the person who scanned.

Stamps, visits, classes, events

The same scan works for anything you count at the door or the counter, with up to 6 actions a site.

  • Visits, check-ins and classes

    Every 5th blow-dry free, with the stylist noted at the counter. Or count gym visits, class attendance or entry to an event.

  • A paid members’ club, if you want one

    Keep the card free, or add paid tiers on every paid plan. Users pay on your own Stripe account.

  • Ask your AI how it’s going

    Ask your own AI how many stamps you gave this month. On every paid plan, customers can ask AI about their own card, on your own AI key.

What you need

Each customer with a card is a user of your app, and each plan has room for a set number. For a café or shop, that usually means App or Company.

  • Users count once per person across all your sites. At your limit, new sign-ups wait, and customers you already have are never locked out.
  • Staff who scan count as people on your plan, you included.
  • Loyalty Manager groups are on every paid plan. You can also add staff to your site with only the Scan users permission.
  • On every paid plan, you can turn on “Allow extra users” to go past your limit, for a small monthly price per extra user.

Questions

Do customers need to download an app?

No. They sign in on your site with their email and a one-time code we send them, and their card is right there on their phone. They don’t need a Page Lemon account.

Who can scan a customer’s code?

You, and the staff you give the Scan users permission. On App and up, add them to a Loyalty Manager group, which can scan codes and do nothing else. They open the code with their phone’s camera, signed in to Page Lemon. Anyone else who opens it sees nothing about the customer, and the code is used up.

What if staff scan the wrong person?

Nothing is added until they tap ✓ Confirm. If they tap ✕ Cancel, nothing is added or logged. After a Confirm, the same person can tap Undo within 10 seconds.

Can someone collect stamps twice?

No. Each code works for one scan and stops working within a minute, so a screenshot or a forwarded code never counts. A daily limit, one stamp a day unless you choose more, caps each customer, counted in your site’s time zone.

What happens when a reward is used?

Staff scan the code, choose the reward and tap ✓ Confirm. The stamps it uses are marked as redeemed, not deleted, so the customer keeps their history and you keep the record.

Does it work with Apple Wallet or Google Wallet?

Not yet. The card lives on your own site, and customers open it in their phone’s browser. They can add your site to their home screen and open it like an app.

Does it connect to my till?

No. Stamps come from a staff scan, not from your till or card machine.

Which plan do I need?

To test the card as a customer yourself, any plan works, Free included. For a café, salon or shop with regulars, choose a plan with room for enough users. Staff who scan count as people on your plan. See What you need on this page, or compare plans on the pricing page.

Can I use it for more than stamps?

Yes. Up to 6 actions a site: stamps, visits, check-ins, class attendance, event entry and the rewards they lead to. Your AI sets them up when you describe them.
