CA Contactless Payment System is a unique innovation in point of sale payments. The system does not accept traditional transactions done by either cash or conventional credit or debit card design. Users have to place a card or other item in proximity to a piece of cashiering hardware in order to complete the transaction. Connectivity is often achieved by radio-frequency devices. No PIN numbers or other verifications are required.
Contactless Payment Systems differ from traditional transactions that follow conventional credit or debit card design. Because of the less stringent security arrangements of the contactless payment system, this system has seen slow adoption in conventional retail. Companies like McDonald's have been experimenting with contactless payment systems for some years. Now, innovators like Apple also offer contactless payment systems. Another good example of a contactless payment system is an RFID device commonly used for highway or local road toll systems.
Contactless payment systems have been adopted recently in highway toll systems because of the convenience they provide overrode security concerns. That same philosophy, however, has not yet been adopted in general retail, where many buyers and sellers prefer using a card with qualifiers like PIN numbers.
