Create customer accounts in Dotypos. These accounts will represent individual customer cards with a code. Each customer account created should therefore contain any name and number (in the Barcode field) that is hidden in the QR code on the card (customer card number). The customer accounts will thus correspond to the customer cards purchased. The best way to create a larger number of customer accounts is to import them. You can also set a customer account to expire on a specific date.

Once you need to create a voucher, scan the customer card and then enter the amount to top up the customer credit. When the customer pays for the credit, they receive a card, which is effectively a voucher for the credit they have earned.

If the customer wants to pay with a voucher (credit), just scan the customer's card at the time of sale and make the payment with credit. If you have set an expiration date for the corresponding customer account, you will be notified in case of expiration. The customer must use the credit by the set expiration date.
