Data Storage on a Rfid Tag for a Distributed System

RFID tags can store more than just a tag ID. Data on an RFID tag can be updated through local processing. This is in contrast to the EPC global standard of data-on-network. The research study explores how much data can be stored on an RFID tag. The scope of this study is to find a suitable data format for data stored in the tags. Two data formats viz CSV and XML along with compression techniques were discussed. The experiment conducted using the prototype examinedhow relevant data can be stored in the RFID tags and used in local processing without the need for a central database or network connectivity. The findings of the experiment results demonstrate sufficient proof of concept to suggest CSV data format. Issues encountered in the experiment are discussed, particularly related to writing data into the tag. The conclusion explores the direction for future research on improving writing data on tag, using the data-on-tag approach.
