Abstract: An RFID assembly and an assembly method thereof are provided. The assembly method for an RFID assembly comprises a step of providing at least one integrated circuit which includes at least one IC contact and at least one dielectric layer, and a deposition of at least one electrical contact and of at least one re-passivation layer. The at least one electrical contact is deposited on at least one first portion and the at least one re-passivation layer is deposited on at least one second portion, which is distinct of the at least one first portion.

Abstract: The present disclosure relates to a NFC communication system, to a method of establishing communication between a wireless communication device and a passive NFC device and to a passive NFC device. The passive NFC device includes an NFC controller, an NFC transceiver coupled with the NFC controller, and at least one persistent flag coupled with the NFC controller, the persistent flag being switchable between an activated state and a deactivated state. The NFC controller is configured to perform a logical operation being divisible into a sequence of at least a first subtask and a second subtask and the NFC controller is configured to ascertain the status of the persistent flag. The NFC controller is further configured to selectively perform at least one of the first subtask and the second subtask on the basis of the status of the persistent flag.

Abstract: A tamper-evident RFID Tag (100) and a method for manufacturing it. The method (500) may provide (510) at least one protection layer (151) before being cured (520) such as to turn the at least one protection layer (151) into at least one degradable layer (155), and to prevent an assembly or a reassembly of the tamper-evident RFID Tag (100) after any attempt of harvesting of the tamper-evident RFID Tag (100).
