Radio Frequency Identification (RFID) uses radio waves for communication between a tag (data carrier or RF transponder) and a RFID Reader. The tag usually consists of a microchip attached to an antenna. The reader is usually capable of reading data from and writing data to the tag.
Using RFID tagging for stock control offers several advantages
Item Search : tags can be read remotely, often at a distance of several metres, even missing items are easily located
several tags can be read at once, enabling an entire pallet-load of products to be checked simultaneously
tags can be given unique identification codes, so that individual products can be tracked
certain types of tag can be overwritten, enabling information about items to be updated, e.g. when they are moved from one part of a factory to another
Days Saved: Without RFID, Stock taking usually requires closure of establishment for a day or two.
