Abstract

A computer program stored in a memory unit of an electronic near field communication module for near field communication devices in environments with different data formats according to different protocols is able to carry out a first initiation operation using a first data format according to a protocol of a first standard, a second initiation operation using a second data format according to a protocol of a second standard, a delay operation, and is able to repeat these operations in a repetitive process. Such devices can search their environment periodically for available RFID tags, RFID readers, NFC multifunctional devices, or the like. The delay can be fixed, variable in length, or both fixed and variable delays can be used. The invention enables for instance a mobile phone to act as an RFID reader of multiple tag formats, to emulate a tag, or to communicate with other NFC devices.
