modes of operations, active and passive. During the passive mode the user generates a radio frequency field (RF) to energize the target, in return the target responds by a load modulation scheme on the field that is generated by the user. In active mode both the user and target devices generate their own Radio frequency field. The user sends information on a radio frequency field and the target answers on another Radio frequency field. Near Field Communication Requirements: NFC technology generally
