With RFID, the devil is in the detail. Several analysts correctly foresaw the tripling of the RFID business by value in recent years. However...
Radio Frequency Identification (RFID)
Radio frequency identification (RFID) is relatively a new AIDC technology which was first developed in 1980’s. The technology acts as a base in automated data collection, identification and analysis systems worldwide. Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data. Unlike a bar code, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object. It can also be read only or read-write enabling information to be either permanently stored in the tag or it can be read-write where information can be continually updated and over-written on the tag.

Benefits of RFID in Retail
Inventory Shrinkage (Shrink) Reduction
• Ability to track items in real-time between manufacturer and point of sale.
• Real-time notification of any breaches in security for non-payment.
• Reduces shrinkage of stock caused by theft.
Monitor unattended inventory
• Automatic item identification on mixed pallets
• "Smart Shelf" systems – designed to provide real time tracking and lovating of tagged items on shelves
• Shipping and Receiving applications
• Real-time notification of out-of -stock items
• Improvement of product replenishment
• Improved product forecasting from product stock tracking
• Reduce labour/time cost of employees
• Reduce time in queue
RFID Smart Labels - extremely flat configured transponder under a conventional print-coded label, which includes chip,antenna and bonding wires as a so-called inlay. The labels—made of paper, fabric or plastic.
Types of RFID Tag
UHF (Ultra High Frequency) Tags, Labels and Cards operate at a frequency of 915 MHz. These types of tags are considered “Passive” –with no on-board power source. Commonly specified by retailers within the supply chain, these tags must comply with the international recognized standard set by EPCglobal.
HF (High Frequency) Tags, Labels and Cards operate at a frequency of 13.56 MHz. These types of tags are also “Passive” with no onboard power source. RFID applications that use HF RFID tags are typically the applications that require read distances of less than three feet. HF tags work better on objects made of metal (RFID Metal Tag) and can work around goods with high water content.
LF (Low Frequency) Tags, Labels and Cards are low-frequency tags (125khz) use less power and are better able to penetrate non-metallic substances. These types of tags are also “Passive” –with no on-board power source. They are ideal for scanning objects with high-water content, such as fruit, but their read range is limited to less than a foot.
