I received a text message saying that my phone was saved on file for future express purchases. What does this mean?

When you made your last payment, your phone number was saved on file.  This feature is similar to a merchant storing your credit or debit card number being saved when you make an online payment, so you do not have to re-enter your account information on subsequent transactions with that merchant.

Phone on File is a one click solution for your mobile payments, which means that once you register, your transactions will be pre-authorized for up to a limit of £100 or 90 days on the merchant for which you opted in to use this service.  For subsequent purchases, you will only be charged when you choose to make a purchase and select “buy”.
