Visa gift cards cannot be exchanged for cash, but Square, a card reader for small companies to accept credit card payments, can help. Some articles advise utilising PayPal, but since these gift cards cannot be validated, PayPal isn’t always reliable. Another choice is Square, although using it will cost you a portion of the money you transfer as well as the reader’s price, if you decide to buy one (details are in the “Tips” section). Please be aware that some customers claim Square has begun to restrict Visa gift cards for specific customers. There may be a solution, but there is no assurance it will work.
