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.
