How do Contactless Card Readers Work?
Contactless card readers operate on radio-frequency identification (RFID) technology, facilitating swift and secure transactions without direct physical contact. When a user taps their card equipped with an embedded RFID chip, near the reader, a magnetic field is generated. This field powers the RFID chip, initiates communication between the card and the reader.
The contactless card then transmits a unique transaction code to the reader, ensuring each payment is distinct and secure. This process uses induction technology, where the induced electrical current in the RFID chip is rectified and utilised for data transmission.
With a simple tap of their card or phone, users can swiftly complete transactions using contactless payments. This convenient method allows information to flow rapidly from the contactless card to the reader's antenna.
Dynamic authentication and other security measures minimise fraud risks, making contactless readers a secure choice loved by many industries. By providing fast, easy, and safe purchases, these seamless systems have been broadly embraced, benefiting both customers and businesses.
