# Wallet loyalty

> Loyalty platform for merchants: programme management, subscription billing, a developer API, and POS, email and CRM integrations.

**Sector:** Loyalty platform operator
**Year:** 2026
**Role:** Team of three
**Stack:** Node.js, Express, Prisma, PostgreSQL, Google Wallet, Apple Wallet
**Runs on:** Google Cloud
**What it does:** The card updates itself — in Apple and Google Wallet

## The problem

Loyalty programmes usually mean another app nobody installs. Putting the card in the wallet the customer already carries removes that objection, but it moves the difficulty onto the merchant side: issuing and updating passes, running programmes, billing, and meeting whatever systems each merchant already uses.

## What we built

A platform issuing loyalty passes to Google and Apple Wallet, with a merchant portal for running programmes, an admin console, subscription billing, a developer API with keys and webhooks, and an integration hub for POS, email and CRM systems.

## The long version

Built and launching. The platform is complete and going live rather than
running at scale, so there are no results to report yet. This study says what
was built, and will carry outcomes when there are real ones to carry.

The design bet is that a loyalty card belongs in the wallet the customer
already has rather than in an app they have to be persuaded to install. That
moves the engineering onto the merchant side: issuing and updating passes,
managing programmes, billing merchants, and meeting whatever POS, email and CRM
systems each merchant already runs through one integration hub rather than a
bespoke build per merchant.
