A point of sale terminal (POS terminal) is an electronic
device used to process card payments at retail locations.
A POS terminal generally does the following:

debit card
✗ Checks whether the funds in a customer’s bank account are sufficient
✗ Transfers the funds from the customer’s account to the seller’s
account
✗ Records the transaction and prints a receipt
