Yeah - I'm fairly certain payment terminals, USB or otherwise, do not provide credit card numbers in clear text. Any card information is encrypted on-device, then sent to the payment gateway - and the readers usually have some sort of anti-tamper stuff to at least prevent them from being opened up and the encryption key compromised or the hardware hijacked.
- imroot 4y agoFiPay (which is one of the pieces of software you can run with Verifone terminals) can be configured to return a credit card number back, but, it's only for legacy point of sales applications that need to have a number for whatever reason. Even after moving everything to our Verifone vault, we still had those fields in our point of sales database, even if all of the numbers were '4111 1111 1111 1111' and the expiration dates were 2099+. We would pass the "proper" things down for the receipt as text fields (AID/TID/etc) to be printed on the receipt and stored with the transaction log.
- MBCook 4y agoEMV tags gives you parts of the card number (so you can tell the kind of card or put the last 4 on receipt) but you don’t get the full number anymore like with mag-stripe.
