Abstract:
Shopping in the present day usually involves waiting in line to get your items scanned for checkout. This can result in a great deal of wasted time for customers. Furthermore, the technology currently used in checkouts – barcodes - is from another era, developed in the 1970s, before the age of the affordable computing power. In the present world, with computers powering everyday items from children’s toys to wristwatches, we felt like we can improve on the humble shopping experience.
With the increasing prevalence and affordability of radio frequency identification (RFID) tags in everyday authentication systems, RFID holds great promise in the retail world for both customers and stores in inventory control, convenience, and cost savings. Our project utilized these RFID tags to automate the checkout process by building a system that could read the RFID signals of all the objects that were placed in proximity to an antenna platform. This eliminated the need for barcode scanning of each individual item, making checkout a significantly faster experience. Furthermore, as each item has a unique tag, even copies of the same product contrasted to the current UPC model, much better inventory control, recall ability, and monitoring of consumer behavior trends are possible, with privacy concerns considered of course.

We can extend this project in various fields with these following factors
• Flexibility: With Card in your hand there is no need to carry cash you. Simultaneously Card can be an ID, a credit card, a stored-value cash card, token at metro stations, airports etc.
• Time and Manpower reduction: Using Card as payment device the user can save his/her time by using various services at anytime and anyplace and avoiding long queues. Also need of human beings at various cash and ticket counters can be minimized. This improves efficiency and reduces ticket frauds.
• Safety: Using card is safer than carrying cash for an individual.
We can access extend this application for mobile payments which can be the future enhancement.
