How to use
Connect the reader to a PC USB port and install the required PC/SC drivers if they are not already present on the host system. Use compatible middleware or application software that supports ISO 14443 contactless communication to send commands and read tag or card data. Place the ISO 14443 card or NFC tag on the reader’s antenna area; the reader will detect the card and establish a communication session for reading or writing operations.
