 Depending on the economic space, there may be a payment limit on single transactions without the need to input the PIN, and some contactless cards can only be used a certain number of times before customers are asked for their PIN.Contactless debit and credit transactions use the same chip and PIN network as older cards and are protected by the same fraud guarantees.Where PIN is supported, the contactless part of the card may remain non-functional until a standard chip and PIN transaction has been executed.
