Software or Embedded solution - Credit card Terminal

Looking for a software (OR) hardware combined with software / Embedded system solution to swipe CREDIT CARD in a Point of Sale (POS) TERMINAL (at a grocery store) without NFC Communication. I typically have to insert a credit card into the POS terminal to make payment to store.

I have the credit card in my iPhone can is not a physical card with NFC capability. The solution has to be wireless or embedded system that is innovative and able to scan stored credit card in IPHONE.
