Contactless RFID ISO card covers the Low frequency 125KHz, and High frequency 13.56MHz technology, To achieve contactless transmission of data, electromagnetic waves transmit the data between the RFID chip and reading devices. Lots of companies use Contactless card to control physical access. An employee holds their card within a few inches of the reader.
The RFID Contactless cards are optional with finely laminated blank card, and pre-printed cards. the pre-printed RFID cards are done in factory with offset printing, and silk-screen printing.
