METHOD FOR AUTHORISED GRANTING OF A SERVICE AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

Current electronic cards (10), such as, for example, proximity cards, smartcards for short, can transmit data to a reader unit over a range of up to about 10 cm. Boosters are used to improve convenience which in essence represent a wireless extension. This is however not adequate with regards to autonomy, function (as a result of termination) and for the differing applications. A method is disclosed in which the transmission (40) of service-specific codes, stored on a number of different smartcards (10), to a portable device (30) is carried out. The portable device (30) then transmits one or more of said codes via several different communication connections (70) so that access to a service can be activated. By providing services to the corresponding authorised communication connection (70) a modular system is achieved, permitting multiple access for a user to services.
