Radio Frequency Identification (RFID) is becoming attractive technology as an alternative to barcode systems. RFID systems provide an automatic identification method, relying on storing and remotely retrieving data using RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennae. In this paper, we develop a smart shopping system that allows customers to manage their shopping list while shopping and only pay the bill at the checkout counter. The shopping cart has the ability to automatically calculate and display the total prices of all the products inside it. This makes it easy for the customer to know how much he or she has to pay while shopping and not at the checkout counter. This way the customer can also control his or her budget and receive faster service at the checkout. An advantage for the shop owners is that they would need a fewer cashiers, which would result in a large cut in their costs. In this paper, we also provide a mathematical model to calculate the estimated delay for each cart to access the system through the ad hoc or WLAN networks.
