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;
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 readersstoring the read data into a portion of memory;
extracting the data from the memory into fields, wherein the fields comprise at least one of card number, site code, manufacturer data, and user data;
reformatting the data in each field to match the second set of characteristics; and
comparing known data for a field with reformatted data from the corresponding field.

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.

13. 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; wherein the at least one reader comprises a reader capable of reading a non-RF based credential and wherein the at least one writer comprises a writer capable writing data with changed characteristics back to the non-RF based credential. - View Dependent Claims (14, 15, 16, 17, 18, 19)
