The use of RFID can have a significant impact when incorporated into a suitable project. RFID offers the following advantages:
Readability - RFID tags do not require to be aligned accurately with respect to the reader as with a bar code and can be read through non metallic packaging.
Versatility - The ability to read a number of tags in close proximity and to be able to write data on the tag itself has enabled projects to be implemented that could not have been achieved in any other way.
Security - Most types of tag have a unique factory set identifier. Such tags are ideal for access control, anti-counterfeiting measures, etc. For more detailed information about RFID and the type of applications to which it can be put, see the RFID Journal web site at the RFID Journal
