Localizable Mobile Payment Shopping Cart based on Location Fingerprint Algorithm

The intelligent shopping cart is designed with embedded system, and has small area positioning and navigation, mobile payment, area storage and anti-theft functions. The Android system obtains the Wi-Fi signal strength and MAC address of AP, and sends the RSSI data to the server. The server obtains the coordinates through the location fingerprint database positioning algorithm. Meanwhile, the server can realize the navigation through the global shortest path planning by Floyd algorithm to facilitate customers to find the goods as soon as possible. The shopping cart realizes payment liberalization by setting up a small electronic cash register system. The new shopping cart system is equipped with two weighing boards, which allow customers to weigh bulk goods directly. Zonal storage is intended to protect fragile and frozen goods and reduce losses. The intelligent shopping cart system makes shopping time saving and labor saving, more convenient and faster.
