Abstract
A reader reads electronic tag data and a CRC code from an electronic tag and detects whether the electronic tag data has been received correctly, by using the CRC code. The CRC code is generated from reader data and electronic tag data stored in the reader and an error detection is performed by using the reader data, so that the error detection is performed simultaneously, and it is possible to selectively read out only the electronic tag data from the electronic tag correlated with the reader data.
Claims17
An electronic tag for storing first information and an error detection code, wherein:
- the electronic tag transmits the first information and the error detection code to a reader for storing second information, and
- the error detection code is generated from the first information and the second information.
An electronic tag for storing first information and a first error detection code, wherein:
- the electronic tag transmits the first information and the first error detection code to a reader for storing second information, and
- the first error detection code agrees with a second error detection code which is generated from the first information and the second information.
A reader for receiving first information and an error detection code from an electronic tag for storing the first information and the error detection code, wherein:
- the reader stores second information, and
- the reader uses the second information and the error detection code to detect an error in the first information.
A system having an electronic tag which stores first information and an error detection code, a reader which stores second information, and a server, wherein:
- the electronic tag transmits the first information and the error detection code to the reader, and
- the reader uses the second information and the error detection code to detect an error in the first information and transmits the first information which is free from an error to the server.
