You can choose to disable Gift Cards if you no longer wish to use them in your store. To do this, follow the steps below:
1. Head to Setup -> Gift Cards.
2. Click the switch next to Enable Gift Cards so that it turns grey.
3. Once you have done this, Gift Cards will be disabled, and you will no longer be able to issue gift cards from Vend.
You will still be able to redeem existing gift cards and view reports on gift cards sold before you disabled this feature.
