Self-Service Checkout System for Groceries

Self-service checkout systems allow shoppers as active participants into a retailer’s business processes. This paper focused on the development of electronic payment in groceries using Near Field Technology. This was done with the use of Radio Frequency Identification (RFID) cards which will replace cash outs and other online-based transactions that are prone to system failures. Several tests were conducted to determine how the self-service checkout system in this study will perform in realworld scenario. The transactions using the self-service checkout system can be finished in less than 41.13 seconds for five items and less. The test in the deduction of current balance by the system yielded 100% accuracy. In terms of security, the system does not rely only on video surveillance of a particular establishment because it has its own security mechanism that is enabled by a microcontroller. The security mechanism that matches the weight of the groceries calculated by the software program and the weight of the groceries weighed by the shopper yielded 100% accuracy during the testing. The self-service checkout solution in this study can provide a more time-efficient shopping experience to time-constrained users.
