Combination of NFC Technology and Transportation Cards
NFC (Near Field Communication) is a wireless communication technology based on radio frequency identification (RFID), featuring a simple and efficient working principle. NFC establishes a short-range communication connection between two devices using high-frequency radio waves, typically transmitting data over distances of just a few centimeters. Its principle is similar to that of RFID technology (with NFC being a subset of RFID), but NFC offers faster transmission speeds and more efficient data exchange. Specifically, when two devices are close enough, they can exchange information such as identification and payment data via the NFC communication protocol.
With NFC technology, transportation cards can quickly transmit data to transportation equipment (like card readers). NFC communication usually operates at a high-frequency signal of 13.56 MHz, allowing NFC devices to transfer information at high speeds over a short range without needing physical contact. As long as the user brings the NFC transportation card close to the card reader, the system will automatically read the card’s data and complete the payment or identify verification process.
How NFC Transportation Cards Work
The core component of NFC transportation cards is the NFC chip. This chip is typically embedded inside the transportation card to ensure that it can communicate with the corresponding card reader. When the user passes through a transportation gate or other device with the card, the NFC chip wirelessly transmits the identity information, balance, or other data stored in the card to the card reader of the transportation system.
During this process, the card reader sends a signal to establish a connection with the NFC chip in the transportation card. Upon receiving that signal, the NFC chip responds by returning the stored information (like account balance, ride records, etc.) back to the card reader. The card reader then determines whether to allow the card to pass through the gate or continue using it based on the validity of the received information. This process is seamless, efficient, and has minimal delay. Users simply need to approach the device to complete all required operations.
