Patent number: 7737822Abstract: A method recognizes whether a transponder designed for communicating with a communication station belongs to one of at least two groups of transponders. First, for each group of transponders, a check data block that is significant for the group of transponders is generated. Then, the data from the check data block that is significant for the group of transponders is evaluated for the recognition of whether the transponder belongs to the group of transponders.Type: GrantFiled: October 31, 2003Date of Patent: June 15, 2010Assignee: NXP B.V.Inventors: Franz Amtmann, Michael Cernusca, Christian Scherabon
