RFID Cards: Understanding the Technology and Its Applications
What are RFID Cards?
RFID cards are a type of smart card that uses radio-frequency identification technology to store and transmit data. These cards are widely used for identification, payment, and access control purposes. The technology behind RFID cards involves a microchip and an antenna that communicate with a reader device to exchange information. This communication can occur over short distances, typically a few inches, and does not require direct contact between the card and the reader.
The use of RFID cards has become prevalent in many industries due to their convenience and efficiency. For example, in the transportation sector, RFID cards are used for toll collection and public transit fare payment. In the healthcare industry, they are used for patient identification and medical record access.
