I bet your shopping experience in a supermarket is usually marred by the long queue and waiting time just to pay for your groceries at the cashier's counter. Currently, the cashier aims each individual bar code at the bar code reader which takes a long time especially if you have cartful of stuff. Wait, there's hope. RFID ( radio frequency identification ) lets you pile up their stuff and pass through the cashier without any waiting since RFID doesn't require direct contact or line of sight scanning. The total bill is tallied instantly and the amount is then deducted.
This technology is currently popular with logistic operations. These radio tags are not cheap and is suitable for use for bulk or goods packed in carton or crates. Besides supermarkets, libraries can make use of this technology to track the books as well as to understand the borrower's profile. RFID technology is also applied in the transportation sector. In Singapore, motorists entering restricted zones pass under the gantry which automatically deducts the toll fee from a cash card placed in the. Commuters in public buses and subways employ tickets which allow commuters to move over the reader at the entry and exit points. There's no need to insert the card into any ticketing macine or slotting them into entry and exit gates. This definitely facilitate traffic movement and cut down any bottleneck during peak hours.
RFID technology consists of 3 parts. The antenna and the transceiver ( normally comes as one component) and the transponder which is the tag. The antenna transmit radio frequency signal to the transponder and the transponder then feedback data to the antenna and action can be taken such as carrying out a payment transaction.
