An intelligent RFID checkout for stores

In this article, we propose an intelligent RFID (Radio Frequency Identification) checkout to facilitate access and payment, to assist visually impaired people and to improve marketing strategy. To avoid saturated queues which we used to see in conventional stores remote identification of the customer and items is used to purchase the latter. Payment is then performed by to online payment or by ATM or credit cards. In addition, to ensure high performance and smooth operation of this checkout, we thought of seven major criteria namely: · Improving marketing strategy by displaying specific advertisement for each customer depending on the history of his previous purchases. · Vocally assisting vocally the visually impaired people (Vocal Messages: welcome, total, confirmation...) · Checking the validity of products during purchase process to avoid sales of expired unhealthy products · Adding a biometric security level by using fingerprints so that the customer can confirm his identity and validate his purchase. This makes steeling others' identity cards useless. · Enabling the customer performing the transaction faster by automatic online payment and sending electronic invoice to his inbox. · Offering to the owner the possibility to check and supervise the history of transactions via internet. · Saving energy by activating the RFID reader only if a user enters or leaves.
