First Claim
Patent Images
1. A method of updating an access control system, comprising:
- reading data from a first RFID credential that utilizes a first set of characteristics to communicate with RFID readers;
changing at least one characteristic of said data such that at least one characteristic in the first set of characteristics changes, resulting in a second set of characteristics; and
writing the data with the second set of characteristics back to the first RFID such that the first RFID utilizes the second set of characteristics to communicate with RFID readers.

Abstract
Methods and apparatus for updating secure access credentials are provided. More specifically, data from one or more RFID credentials can be read and subsequently written to one of the original RFID credentials reducing multiple RFID credentials to a single credential. The RFID transponder on the credential that has new data written thereon does not necessarily need to have the same functionality as the RFID transponder on the other RFID credentials that was read.

17. A device for updating one or more RFID credentials, comprising:
-
a reader portion utilizing a first set of characteristics for reading data from a first RFID credential;
a processor operable to alter characteristics of the data such that at least one characteristic in the first set of characteristics alters, resulting in a second set of characteristics; and
a writer portion utilizing a second set of characteristics to write the altered data with the second set of characteristics back to the first RFID such that the first RFID utilizes the second set of characteristics to communicate with RFID readers. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A system for updating one or more RFID credentials, comprising:
-
at least one reader capable of utilizing a first set of characteristics to read data from a first RFID credential;
a processor for changing characteristics of the read data such that at least one characteristic in the first set of characteristics changes, resulting in a second set of characteristics; and
at least one writer capable of utilizing a second set of characteristics to write the changed data with the second set of characteristics back to the first RFID such that the first RFID utilizes the second set of characteristics to communicate with RFID readers. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
