Visa payWave is a contactless credit card issued by Visa. It has an antenna coil with radio wave transmitting and receiving functions. It is a composite chip card (Dual Interface) that combines contact and contactless. Function, when the Visa payWave card is used with a general card swipe machine or a touch card reader, the chip module will automatically determine according to the card reader type to perform the contact or contactless function.
In September 2007, Visa launched the Visa payWave contactless payment technology feature, which allows cardholders to wave their card in front of a contactless payment terminal without the need to physically swipe the card or insert the card into one Point of sale equipment. This is similar to MasterCard's PayPass service and American Express's ExpressPay, which both use radio technology (RFID).
