Abstract

The present invention discloses a method for using RFID tags as carriers for digital calibration certificates and its system, which consists of following steps, i.e., generating standard DCC data; simplifying the DCC data to obtain the DCC-Lite data; after that, the DCC-Lite data is split into obtain multiple XML Lite files; and then, storing and writing multiple RFID tags in the multiple XML Lite files so that the DCC-Lite data can be spliced and restored by reading XML-Lite file information stored correspondence to the multiple RFID tags. The present invention realized unimpeded reading and application of instrument calibration information and data in the off-line state by means of simplifying, segmenting DCC files and storing them in multiple RFID tags respectively. Furthermore, the present invention may also split and store certain DCC-Lite with large amount of data in multiple RFID tags by splitting and splicing its content.
