1/ It is possible to "top up a voucher" directly in every GG establishment. In other words, create credit on a voucher and, for example, sell it to a client or give it to a client with a top-up or preset amount of credit.

2/ These are pre-generated vouchers that must be physically available in each establishment.

3/ The voucher is activated after it has been paid and scanned.

4/ Once the voucher credit is used, it becomes a spend.
