(Product ID: 3335)

Do you want to use your phone for your 125 kHz Access Control? With plastic 125 kHz stickers, you can do it easily. Just place the sticker under your phone cover, register your new ID and that is it.

The EM4200 chip is read-only, it operates on a frequency of 125 kHz, and is made by chip manufacturer EM Microelectronic-Marin. It is the latest version and backward compatible with previous chips EM4100 and EM4102. It contains a read-only identification number, which is programmed with a laser during its manufacturing process and cannot be changed.

Our stickers are made from plastic material, are waterproof, and contain a bigger antenna which helps to get better performance. These stickers work with standard 125 kHz read-only readers and deliver the longest reading distances. They are used for access control, time attendance applications, and for asset or people identification.

Plastic RFID stickers with 125 kHz chip EM4200 are a special kind of RFID transponder with a plastic layer on top and an adhesive layer on the bottom. They contain a standard RFID chip and a copper antenna. The EM4200 chip is a read-only chip produced by chip manufacturer EM Microelectronic-Marin and it’s a very popular RFID chip which operates on a frequency of 125 kHz. It is used in countless applications for people, assets, and even animal identification purposes.

The EM4200 was designed to replace directly the EM Microelectronic-Marin Read-Only ICs EM4100/4102 and EM4005/4105. It works perfectly even with readers designed for its competitor’s chip TK4100, and achieves better performance on these readers, too.
These 125 kHz stickers are waterproof, they have a diameter of 38 mm and they are approximately 1 mm thick.

The stickers are bright white, without numeration or other printed elements. 
You are welcome to buy white cards from stock or send us an inquiry for printed cards. Depending on the quantity and deadline, we will help you select the best option for printing.

Reading test for Plastic RFID stickers with 125 kHz chip EM4200  

The reading distance between the RFID transponder and the reader is affected by many different factors, like the size of the antennas and quality of the chips, the interferences of metal, and electromagnetic signals, etc.

We tested the EM4200 125 kHz stickers with different kinds of readers and measured the reading distances. This is not an official test, and it was made to provide information about what reading distances you may expect with your application.

Below are the distances we measured with our test:
RFID Reader Reading distance
Syris RD200-LF 5,5 cm
Promag PCR-330A-00 125 kHz RFID Card Reader 3 cm
125 kHz RFID reader R80D 1,5 cm
