RFID & Automatic Identification Technology

RFID and Automatic Identification Technology has grown a lot since it was first popularized by superstores such as Wal Mart, K-Mart and others. You can expect that this technology will develop even more with the coming Internet of Things trend, since many dumb devices can be made into some sort of a smart device, simply by adding an RFID tag.  These tags are superior to bar codes as the serial number transmitted by the tag is not easily visible to a casual observer (unlike abar code which can be easily photographed and printed). So there is a degree of protection when using such smart tags instead of the older bar codes.
