125kHz EM4100&EM4200 RFID Card

The operating frequency of the EM4100 proximity card is 100 kHz~150 kHz. Each EM proximity card has a unique serial number. EM4100 proximity card is an ideal solution for access control and time attendance systems and does not require a high level of security.

Since the EM chip is not only compatible with the ISO 11784/11785 standard chip but also meets the ISO FDX/B animal identification standard, the chip can be widely used in various application management systems, especially animal identification and tracking management.

We provide blank cards and pre-printed cards.

Frequently Asked Questions About RFID Card

An RFID card refers to an identification badge/ credit card designed to transfer data to an RFID interrogator. The card contains an RFID tag with sufficient memory to capture valid cardholder's information. Also, the RFID card can be made from different materials, including plastic and PVC. 

RFID card is a packaging form of RFID Tag in an RFID system.RFID uses radio waves to accomplish this task. Simply put, an RFID system consists of three components: RFID tags or smart tags, RFID readers, and antennas. The RFID tag contains an integrated circuit and an antenna, and the RFID reader provides energy to the RFID tag for wireless data exchange.

RFID cards include low frequency cards, high frequency cards and UHF frequency cards.

RFID cards are widely used in access control management, hotel management, all-in-one card management, library management, membership management, student management, public transportation, parking management, etc.

There are many RFID cards with different chips and processes, and the price ranges from 10 cents to 55 dollars. It depends on the type of RFID card, the card's processing process, the number of orders, and other factors. If you want to buy some RFID cards, you can contact us. We will provide you with a reasonable quotation based on the RFID card you want.
