FUTURE OF PRODUCT TRACKING AND IDENTIFICATION
Imagine going any supermarket in Nairobi, filling up your cart and walking right out the door, without having to endure those long lines at the cashier. No longer waiting as someone rings up each item in your cart one at a time. This might soon be happening thanks to RFID (Radio Frequency Identification) technology. RFID tags on each item will communicate with an electronic reader that will detect every item in the cart and ring each up almost instantly. The reader will be connected to a large network that will send information on your products to the retailer and product manufacturers. Your bank or mobile service provider, due to the MPESA users, will then be notified and the amount of the bill will be deducted from your account .No lines, no waiting.
Radio-frequency identification (RFID) involves use of electromagnetic fields to transfer data with the goal of identification or tracking. RFID tags contain at least two parts: an integrated circuit for storing and processing information, modulating and demodulating radio signals, collecting DC power from the incident reader signal, and other specialized functions; and an antenna for receiving and transmitting the signal. The tag information is stored in a non-volatile memory. The RFID tag also has fixed or programmable logic for processing the transmission and sensor data.
