The invention is a method of managing a NFC transaction between two hosts and a reader device. The two hosts are embedded in NFC devices and are intended to be identified by the reader device during an anti-collision phase through a first identifier and a second identifier respectively. The first identifier comprises a variable part. The method includes the steps of generating the first identifier, the variable part of the first identifier and the second identifier comprising a common pattern, looking for a common pattern into the first and second identifiers on the reader device side, and if a common pattern is found and if the variable part of the first identifier comprises said common pattern, concluding that the first and second hosts are embedded in a unique NFC device.
