In most cases, the gift cards should still be usable even if they were in the fridge with food for a day. Gift cards are typically made of plastic or a similar durable material, and a short exposure to refrigeration should not affect their functionality.
However, if you want to be absolutely sure, you can take a few simple precautions:
Inspect the cards: Take the gift cards out of the fridge and visually inspect them for any signs of damage, such as warping, discoloration, or cracking. If the cards look fine, they are likely still usable.
Test the cards: If the gift cards have a magnetic stripe or a barcode, you can try scanning or swiping them at the respective stores or online retailers to see if they are accepted. If they have a scratch-off code, you can also check the balance on the retailer's website or by calling their customer service.
Contact customer support: If you are uncertain about the cards' usability or want further assurance, you can contact the customer support of the gift card issuer and inquire about the situation. They can provide more specific information about the card's condition and whether it might have been affected.
In most cases, as long as the cards appear undamaged and the magnetic stripe or barcode is still readable, they should work without any issues. However, it's always a good idea to check them before attempting to use them, especially if they have been subjected to unusual conditions like refrigeration.
