PayWave
In September 2007, Visa introduced Visa payWave, a contactless payment technology feature that allows cardholders to wave their card in front of contact-less payment terminals without the need to physically swipe or insert the card into a point-of-sale device. This is similar to the MasterCard PayPass service, with both using RFID technology.
In Europe, Visa has introduced the V PAY card which is chip-only and PIN-only.
In Australia the major banks, such as the National Australia Bank (NAB), do not allow their customers to opt out of having payWave-enabled Visa cards. The same can be said for MasterCard's contact-less payment systems. Customers who are unhappy with the way payWave permits transactions without the requirement for either PIN or signature have been advised to refrain from having a Visa card attached to their account.
