For cafés, bakeries and small shops
A loyalty card your customers carry on their phone
Users sign in on your site and show their code at the counter. Staff scan it with a phone to add a stamp. Users see their card and ask AI about their own visits, like “How many stamps did I get this year?”.
- QR stamps at the counter
- Each user’s own card
- AI answers from their own visits
This is for you if you say
- “Paper stamp cards get lost, and I can’t tell who my regulars are.”
- “I want a loyalty card on my own site, not another app for customers to download.”
- “Customers keep asking how many stamps they have.”
The problem
Paper cards get lost and stamp apps charge per customer, while your regulars only want to know when their free coffee is due.
How Page Lemon helps
Your AI adds a users’ area to your café’s site. Page Lemon runs the sign-in, each user’s card, the QR scan at the counter and the AI on your own key, which only reads that user’s own visits.

Questions
Do customers need to download an app?
No. The card is part of your website, so it works on any phone, and users can add it to their home screen.
Who pays for the AI?
You do, through your own AI key: your provider bills you for each answer. We sell no AI credits.
Can a user see someone else’s visits through the AI?
No. The AI only reads what that user could already see: their own card and visits.
Is there anything I can’t build with it?
Yes. Apps are for adults only, and not for health, mood or therapy records, or for card, bank or ID numbers (Acceptable Use). Users pay through Stripe, which holds their card details.
