Description

Technical Field

[0001] The utility model relates to the technical field of public transportation electronic information, in particular to an NFC card swiping device. Background Art

[0002] NFC, or near field communication, is a short-range, high-frequency wireless communication technology. End-to-end data information can be exchanged by approaching each other. NFC is an integration of contactless radio frequency identification (RFID) and interconnection technology, which can realize point-to-point communication functions and is mostly used in mobile terminal payment and electronic ticketing. For example, when taking public transportation with NFC, by entering the electronic information of the bus card into the mobile phone, the payment can be completed by bringing the mobile phone close to the NFC payment terminal, which greatly improves the convenience of passengers taking public transportation.

[0003] However, the existing NFC card swiping and fare deduction devices on buses only accept one card swiping device approaching to swipe the card at the same time. Therefore, it is easy to cause passenger congestion at the door. When the vehicle starts, it is not conducive to the passengers to stand stably in the car, which poses a safety hazard. Therefore, we propose an NFC card swiping device that can improve the card swiping efficiency and avoid congestion at the door. Utility Model Content
