Holtek – BC45B4522 – NFC Reader

Near Field Communication is a type of RFID operating in the high-frequency range (13,56MHz), commonly employed in applications with a short contact range. The technology involves data exchange between two devices, typically an NFC reader and an NFC tag, establishing a high-frequency magnetic field for communication. Two prevalent signaling technologies, type A and type B of the ISO14443 standard, utilize distinct encoding methods.

When selecting NFC readers, considerations include ISO standards, supported interfaces, power consumption, and other features to enhance performance and ensure secure operations.
