The fixed RFID reader-writer is installed at the settlement station, places the commodity that has the RFID label on the settlement station, and the RFID reader-writer just can be fast accurate reads label data to transmit data through TCP network communication, there are two kinds of network connection modes on the RFID card reader: wifi and ethernet are connected, can customize according to the demand, and the protocol of data transmission safety consideration, transmission data can privately customize. The RFID identification tag is very accurate and quick, 120 goods can be identified and finished only within 3 seconds, efficiency is improved by hundreds of times compared with the traditional goods one-to-one code scanning, and each bar code data is unique, so that misreading or repeated statistics is avoided.
The industrial intelligent flat-panel equipment is independently isolated from the RFID reader-writer through a wireless connection network, namely, the flat-panel equipment can be interconnected without mutual influence. The self-service settlement application is operated on a flat plate and is also used for receiving and displaying commodity information read on the RFID reader-writer, a commodity detail database is arranged in the self-service settlement application and stores commodity detailed information, the commodity unique identification ID transmitted by the RFID reader-writer can be used for inquiring commodity details including commodity names, prices, discounts and the like in the corresponding database, the amount required to be paid is calculated according to commodity real-time to be settled, and if any doubt exists on a settlement result, settlement commodity data correction can be carried out in a re-settlement mode. The application interactions are as in fig. 3.
By means of the existing mature online payment platform, the code scanning payment function is transplanted to a payment link, and in an OpenHarmony system, payment is completed by scanning a payment code through a camera. The application interactions are as in fig. 4.
After the payment is successful, commodity settlement tickets can be printed according to the needs.
The following description is made for a scenario of supermarket shopping:
firstly, a self-service settlement cabinet is arranged on a supermarket settlement table, a fixed RFID reader-writer is arranged in the self-service settlement cabinet, and the reading range is set to be the internal area of the settlement cabinet. A10-inch industrial flat plate is installed above the settlement cabinet, a self-service settlement application program is operated, and a screen faces a customer.
And secondly, an RFID label with preset related data is attached to each commodity, the data on each label uniquely identifies one commodity, and the label is made of wear-resistant and anti-pollution materials so as to prevent damage.
The customer places the purchased commodity in the settlement cabinet, the RFID automatically recognizes the label information, the data are transmitted to the self-service settlement application through the network in real time, and the data security is ensured by the self-defined transmission protocol of the transmitted data. The application program matches the information of names, unit prices, discounts and the like of commodities immediately after receiving the data, displays shopping details, and comprises the following steps: commodity basic information, commodity quantity and settlement amount. If there is a question about the settlement data, the system can be triggered to check through the re-settlement operation.
After confirming the commodity information, the settlement process can be carried out, the online payment can be selected after the settlement is carried out, and the payment is completed through code scanning payment codes, so that the settlement is completed.
The UHF RFID tag is used for replacing paper bar codes, the tag is small in size, low in cost and long in service life which can reach 10 years, and has the advantages of dirt resistance, water resistance and the like.
