For contact chip cards, your customers must insert the chip card into the payment terminal reader instead of swiping the card as they do with a magnetic stripe card. Also, your customers must leave the chip card in the payment terminal reader until the terminal prompts them to remove the card. It is recommended that the customer-facing display prompt the cardholder when it is time to insert and remove the card, so as to train the cardholder both in leaving the card in the reader, and in inserting/removing it at the proper time.
For contactless cards and mobile devices, your customers will simply hold the contactless card or payment-enabled device where they see the Contactless Symbol on the payment terminal.
