EMV cards are inserted into an EMV reader rather than swiped. While inserted, the customer will be required to enter a PIN and/or signature to process payment. Card insertion generates dynamic tokenization data to transmit the cardholderâs verification details. EMV cards can now use the same tokenization technology to pay via contactless readers. To process payment, all a customer needs to do is hold or tap their card over the reader, and the transaction is complete.
