Abstract:
A method of encoding a string of data characters into a wireless, programmable RFID tag, comprising:determining a number of n-bit character codes corresponding to the data characters in the string, the character codes selected from an n-bit set character set that maps a plurality of human readable data characters to respective n-bit character codes, where a subset of the human readable data characters form an m-bit character set that maps the human readable data characters in the subset to respective m-bit character codes, where m is less than n; parsing the number of n-bit character codes to separate the n-bit character codes corresponding to the data characters in the subset from the n-bit character codes corresponding to the data characters not in the subset; converting the parsed n-bit character codes corresponding to the data characters in the subset into corresponding m-bit character codes, and outputting an output string of the m-bit character codes corresponding to data characters in the subset and the n-bit character codes corresponding to data characters not in the subset to program the RFID tag.
