MULTIPLE CONTACTLESS DEVICE INTERACTIONS AND COMMUNICATION PROTOCOLS PER TAP

摘要

Enabling multiple contactless interactions and communication protocols with a single tap of a contactless device. A device reader generates a polling loop and detects a contactless device using an RF field. The device reader identifies the contactless device's communication protocols and initiates a first communication protocol via ISO/IEC 18092 protocol. The device reader initiates a stored value communication via MIFARE protocol. The device reader then initiates an EMV communication via ISO/EIC 14443 protocol. A contactless device can function for both an EMV compliant payment transaction and an alternative peer-to-peer type transaction. The EMV based payment application and transaction is retained as an independent payment application, thereby keeping the additional data exchange process of EMV technology from influencing the peer-to-peer technology and avoiding re-certification of EMV technology.
