Abstract: An object is disclosed, the object (100) comprising a body comprising an antenna; and an integrated circuit embedded in the body and electrically connected to the antenna for receiving and transmitting wireless signals. The integrated circuit receives wireless signals at first and second different frequencies, waits until a command is received at the first frequency from a first reader device before transmitting a first signal and, upon detection of a signal at a second frequency different to the first frequency from a second reader device (201), transmits a second signal without waiting until a command is received.

Abstract: A communication station is suitable for contactless communication with transponders and with further communication stations and has a first protocol-executing circuit and a second protocol-executing circuit, the first protocol-executing circuit being designed to effect communication between the communication station and transponders under a station/transponder protocol and the second protocol-executing circuit being designed to effect communication between the communication station and further communication stations under a station/station protocol.

Abstract: The disclosure relates to performing a proximity check to determine whether a transponder device is in proximity of a reader device. In an example embodiment, a method of performing a proximity check to determine whether a transponder device (220) is in proximity of a reader device (210) comprises: transmitting a command (231, 401, 507) from the reader device (210) to the transponder device (210), the command (231, 401, 507) including a request for a measured response time for a number n of previous command-response exchanges (503-506) stored by the transponder device (220); in response to receiving the command (231, 401, 507) at the transponder device (220), transmitting a response (402, 508) to the reader device (210), the response (402, 508) including a measured response time (4031-n) stored by the transponder device (220) for the previous n command-response exchanges (503-506); and determining whether a predetermined criterion for the proximity check is fulfilled by comparing a measured response time stored by the reader device (210) with the measured response time transmitted by the transponder device (220) in the response (402).
