摘要 |
The device has at least two object modules (1,2), each associated with a defined object and containing transmitter/receiver devices (4,5), and one or more identification emitters (10) with microprocessor(s) (11) exchanging coded data with object modules via bi-directional data communications paths. Different encoding algorithms are placed in a memory element(s) (13) in the identification emitter(s) for selective call up by the microprocessor(s). Independent claims are also included for the following: an identification emitter for exchanging data with object modules and an object module for a keyless access control device.
