Poster POS
Turn every Poster receipt into a stamp in Apple Wallet or Google Wallet without an app and without staff retraining. Adds a voucher engine Poster does not have natively.
Integration layer
Integrations
7stamp is built to start without any integration. Wallet cards already work through Staff Scanner, Self-Service Kiosk, Receipt QR, or Redeem Codes. When you are ready to connect 7stamp with your POS, CRM, or automation stack, the integrations below remove the last manual steps.
Direct POS integrations
7stamp plugs into your existing point-of-sale so every receipt can become a stamp without extra staff action.
Serve POS
Direct integration with Serve POS. Each closed check can issue a stamp to the customer's wallet card automatically.
Your POS not listed?
7stamp works with any POS through Zero-POS Integration: redeem codes, staff scanning, or Receipt QR. New direct integrations are built free of charge when technically possible.
Android payment terminals
Run loyalty on an existing Android payment terminal with Terminal Mode in the 7stamp Scanner app. Install from Google Play or deploy the APK across your fleet.

Not a POS integration, but useful for agencies, integrators, and POS resellers who distribute prepaid 7stamp packages to client businesses.

Most 7stamp customers run loyalty for months without any integration. Staff scan wallet cards from a phone, customers self-stamp at a kiosk, or vouchers carry a redeem code that staff types into the existing POS as a normal promo code.
This is Zero Level Integration: loyalty that runs in the background of an existing business without development, without new staff training, and without changing the POS.
Frequently asked questions
Which POS systems does 7stamp directly integrate with?
Poster POS and Serve POS have a direct integration today. Any other POS can run 7stamp through redeem codes, staff scanning, or Receipt QR without custom development. New direct integrations are built free of charge when technically possible.
Do I need an integration to start using 7stamp?
No. Most businesses launch in under 15 minutes without touching their POS. Integrations remove manual steps only after the loyalty loop is already proving demand.
Can 7stamp send data to my CRM?
Yes. Every card event can be pushed to your CRM through webhooks, including card_issued, stamp_added, goal_reached, voucher_issued, voucher_redeemed, lottery_played, birthday_reached, and inactivity_trigger.
Is the Poster integration free?
Yes. The Poster integration itself is free to install. 7stamp has a Free Forever plan with up to 100 card operations per month, then paid plans from EUR 29 per month per location.
How do I request a new integration?
Contact us with the name of the POS, CRM, or other tool you need. If the technical path is realistic, we build it free of charge.
