Estimating the term…
There is disclosed a method for identifying the type of an RFID tag, comprising the steps of receiving encrypted data from said RFID tag, decrypting said data by at least one decryption method, evaluating if said data has been correctly decrypted by said at least one decryption method, and in case said at least one decryption method has succeeded in decrypting said data, deriving a tag type from said decryption method. Further there is disclosed a device for identifying the type of an RFID tag, comprising a radio frequency identification tag reader for receiving data from a radio frequency identification tag, a decryptor for decrypting said data by at least one decryption method, the decryptor being suitable to evaluate if said data has been correctly decrypted by said at least one decryption method, and a data processing unit suitable to derive a tag type from said at least one decryption method and to generate a corresponding output. Also there is disclosed a device for identifying the type of an RFID tag, containing encrypted data, and comprising a transmitter for sending said data to a radio frequency identification tag reader, characterized in that said encrypted data contains an indication of the type of radio frequency identification tag.
Method for identifying the type of an RFID tag, comprising the steps:
Software tool comprising program code means stored on a computer readable medium for carrying out the method of anyone of the preceding claims when said software tool is run on a computer or network device.
Computer program product comprising program code means stored on a computer readable medium for carrying out the method of anyone of the preceding claims when said program product is run on a computer or network device.
Computer program product comprising program code, downloadable from a server for carrying out the method of anyone of the preceding claims when said program product is run on a computer or network device.
Computer data signal embodied in a carrier wave and representing a program that instructs a computer to perform the steps of the method of anyone of the preceding claims.
Electronic terminal (2), comprising a radio frequency identification tag reader (12) for receiving data from a radio frequency identification tag, a decryptor (14) for decrypting said data by at least one decryption method, the decryptor (14) being suitable to evaluate if said data has been correctly decrypted by said at least one decryption method, and a data processing unit (16) suitable to derive a tag type from said at least one decryption method and to generate a corresponding output.
Radio frequency identification tag (6), containing encrypted data, and comprising a transmitter (8) for sending said data to a radio frequency identification tag reader, characterized in that said encrypted data contains an indication of the type of radio frequency identification tag (6).
Dependencies are inferred from the claim text.
