Is it possible to use gift card several times?

Hello, I would like to know - regardin to gift cards module - if giving € 100 of gift card you can use it in multiple orders from the user and if you can decide how much of the gift card to use. 

Hello

Module "gift cards" is based on prestashop's voucher codes feature.

This means that each time someone will purchase "gift card" - it will purchase a "voucher code".

PrestaShops's voucher codes feature allows to set option named "partial use"

Partial use option - when active - will give you (as a n owner of gift card) to use it several times until its value is exhausted.

and this is an answer for your question:

Unfortunately its not possible in prestashop so also not possible in this module (as it is based on prestashop voucher codes engine)
