What Is a Contactless Smart Card?
A contactless smart card is an intelligent ticket card containing a microprocessor. When using a recharged smart card, you only need to bring the smart card close to the card reader, and no direct contact is required, and the fare is automatically deducted. In the rail transit system, after the reader recognizes that the smart card is valid when entering the station, the smart card records information such as the time of arrival, the name of the station, and the number of the entrance ticket gate.
