Validating customer rewards at the cash register

The mobile cash register runs at /caisse/<your-slug> in any modern browser — phone, tablet, or laptop. PIN-protected per employee, with full audit logs. Your customers earn rewards in seconds.

Initial setup

1. Open /pro/team and create cashier profiles. Each profile gets a four-digit PIN, an avatar colour, and an optional site label.
2. Bookmark /caisse/<your-slug> on the till tablet. The first time you open it, your tier (PRO+) may ask you to approve the device — you do that from the same /pro/team page.
3. Pin the page to the tablet's home screen for a one-tap launch.

What happens at checkout

For a cashback payment:

1. Customer opens their satooB card on their phone — a QR code that rotates every 90 seconds.
2. Cashier opens the cash register, picks their profile, types their PIN.
3. Cashier taps Cashback, scans the customer's QR code, types the basket amount, validates.
4. The reward credits in seconds. Customer sees the confirmation in their satooB account.

For vouchers (customer wants to spend points):

1. Customer presents a QR code or dictates a six-letter code (V-XXXXXX) generated in their account.
2. Cashier scans (or types) the code in the Vouchers screen of the cash register.
3. The voucher is marked redeemed atomically — it cannot be used twice.

Anti-abuse and audit

• Every action is attributed to the cashier who validated it (per-employee daily caps, audit log, security alerts).
• Five wrong PINs trigger a 15-minute lockout, then 1-hour, then 24-hour. The patron is alerted via email at the third attempt.
• 13 months of audit log retention by default. Patrons can export them as CSV from /pro/team.

Tips

• Train cashiers on the cashback flow first — it is the most frequent action.
• Keep the till device on charging; the cash register caches the session for 8 hours but obviously needs a screen on.
• The QR scanner offers a multi-camera picker — handy on tablets with two lenses.
