The NFC concept is designed from the synergy of several technologies including wireless communications, mobile devices, mobile applications and smart cards. So what is
genesis of NFC, why the need for such technology has arisen? The changes or improvements on RFID to expose NFC technology can be described below. First of all
NFC is short range communication, which is good for secure and intuitive interaction
and RFID may use long range especially for active tags that contain embedded energy.
NFC uses only passive tags, that simplifies deployment of NFC system and RFID uses
both active and passive tags. NFC utilizes secure data exchange because of short range
communication, which is a must for mobile payments. And finally IT industry is interested to integrate many services, such as payment, loyalty, identification, access control
and so on, and NFC technology is a response to that demand
