摘要
目前的超市收银大多以人工逐一扫码方式结算,排队结账使人们购物的愉悦感荡然无存,针对这一问题,文中设计了一款基于RFID的超市自助收银系统。该系统分为计费和结账两个独立的模块,计费模块通过扫描嵌入到商品上的RFID标签实现消费金额的计算和显示;可以根据当前购买的情况进行商品数量的增加及其删除,并可以通过OLED显示商品的名称、单价、数量、总计及其当前所有的商品。自助收银系统可以由消费者在没有收银员的情况下完成自助结算,有效提高了结账效率。

At present, most of the supermarket cashier is settled by manual scanning one by one, and the queuing checkout makes people’s happiness of shopping disappear. To solve this problem, this paper designs a self-service cashier system based on RFID in supermarket. The system is divided into two independent modules, billing and billing. The billing module realizes the calculation and display of consumption amount by scanning the RFID tags embedded in the goods. The number of products can be increased and deleted according to the current purchase situation, and the name, unit price, quantity, total number of products and all the current products can be displayed through OLED. Self-service checkout system can be completed by consumers without cashiers, which effectively improves the checkout efficiency.
