And in Mexico many merchants have the POS terminals separate from the sales system (they use standalone POS terminals). This poses a problem for mobile payments because sometimes the merchant may require cashiers to enter more than the last four digits of the payment card number when they are recording the sale in their system using a computer. Which would defeat the purpose of not having to pul out the wallet, since mobile wallets don’t give more than the last four digits of the device account number.
For example, Bed Bath & Beyond stores require cashiers to enter the first six digits of the card number when recording a sale paid by credit card. Autozone stores require them to enter the whole card number and expiration date (or swipe the card in a magnetic stripe reader attached to the computer, which is not used to process the payments but just for recording card info on the computer with each sale) in order to record a sale paid with credit card. And the Federal Commission of Electricity, Mexico’s government owned and operated electricity provider, requires cashiers to enter the first six and last four digits of the card on credit card payments in order to record the credit card payment and credit it to the customer’s account.
