What is another word for contactless card?
Pronunciation: [kˈɒntaktləs kˈɑːd] (IPA) 
A contactless card is a payment card that enables transactions without physical contact between the card and the terminal. Synonyms for contactless cards include tap-and-go cards, wave cards, proximity cards, and RFID cards. Tap-and-go cards refer to the simple action of tapping the card on a terminal to make a payment. The term wave cards is used because the wave of the card near a terminal is sufficient to authorize a transaction. Proximity cards refer to the fact that the card must be close to the terminal to be detected, without any physical contact needed. RFID cards, on the other hand, are contactless cards that rely on radio frequency identification technology to help facilitate transactions.
