Customer code not found or refused

Code not found: the 4-digit code is specific to each card. Ask the customer to read it from their card, or search by name (2 characters minimum). If they have not added the card yet, have them scan the QR code.
Several cards: a customer can have one card per programme or per location. On the Multi-site plan, choose the right location before scanning.
"Already stamped a few seconds ago": Goodly asks for confirmation to avoid a double stamp. Confirm only if it is intended.
Till mode blocked: after 30 unknown customer codes in one hour, an employee code can no longer look up records for one hour. A refusal outside hours, outside the area or beyond the limit comes from the till mode protections.
Suspended or unpaid account: stamp distribution is suspended until the situation is resolved, see Dashboard blocked.
