Problems solved by technology

Although it is possible to ensure a good identification of whether a transponder designed to communicate with a communication station belongs to one of at least two groups of transponders, the known solution has the disadvantage that in the group request A separate data block (i.e. AFI data block) is required in the parameter section of the signal to allow identification of whether a transponder belongs to a transponder group
For its transmission from the communication station to the transponder, unfortunately, such an independent AFI data block requires an additional transmission time interval, and in addition, such an independent AFI data block has a negative impact on the transmission spectrum, so it is found that this Known solutions really need improvement

Embodiment Construction

[0029] FIG. 1 shows a communication station 1 , and FIG. 2 shows a transponder 2 . The communication station 1 comprises a circuit 3, which is implemented as an integrated circuit, although this does not necessarily have to be the case. The transponder 2 contains an integrated circuit 4 . The communication station 1 and the transponder 2 are designed to communicate with each other without contact. In a typical application, a plurality of transponders 2 can communicate with the communication station 1 , wherein the transponders 2 are located in the communication area of ​​the communication station 1 . The transponders 2 are thus divided into different transponder groups, wherein this subdivision may already take account of very different aspects. For example, the division of products that can be purchased in a food supermarket can be performed based on item numbers and prices. The division can also be made according to different commodity types, such as cosmetics, beverages,...

Abstract

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.

Description

technical field [0001] The invention relates to a method for distinguishing whether a transponder designed to communicate with a communication station belongs to one of at least two transponder groups, according to which method a communication station designed to communicate with a transponder transmits to the transponder A request signal comprises a command data block and a test data block, and according to the method, the data contained in the request signal are evaluated in the transponder in order to identify whether the transponder belongs to a transponder group. [0002] The invention also relates to a communication station for communicating with a transponder belonging to one of at least two transponder groups. [0003] The invention also relates to a circuit for a communication station for communicating with a transponder belonging to one of at least two transponder groups. [0004] The invention also relates to a transponder for communicating with a communication sta...
