Swipe the card through a magnetic card reader, insert the card into a chip-reading device, or wave the card in front of a Visa payWave contactless payment terminal to request the transaction authorization.
Note: Many Visa cards have a chip that communicates information to a point-of-sale terminal with a chip-reading device. If a chip-reading device is available, preference must always be given to chip card processing before attempting to swipe the magnetic-stripe. The card should remain in the terminal until the transaction is complete.
