 KEY FOBS
Are you looking for a handy 125 kHz transponder for unlocking your doors, recording work times, paying for a coffee at a vending machine, or other identification purposes?

We offer high quality, prestige 125 kHz key fobs with the very commonly used EM4200 chip.

The upper part of the key fob is made of stainless steel and the lower part is made of an imitation black leather material. This key fob has a long lifespan, good performance, and is different than the usual plastic RFID key fobs.

The EM4200 chip is read-only, it operates on a frequency of 125 kHz, and is backward compatible with previous chips EM4100 and EM4102 – as well as the competitors’ TK4100 chip. It contains a read-only identification number, which is programmed with a laser during its manufacturing process and cannot be changed.

The RFID key fobs with 125 kHz EM4200 chip work with standard 125 kHz readers, access control and other identification devices.
For orders above the 100 pcs., we can do various customization services like printing company logos, serial numbers, or other personalization.

You are welcome to buy prestige key fobs from stock or send us an inquiry for customized key fobs. Depending on your requests, we will help you select the best option.

INFO

RFID key fobs are basically RFID tags in the form of a keychain and are very convenient to carry around. They can unlock the doors, pay for a coffee at a vending machine, or can be used to identify users in various other RFID applications. 

The upper part of the prestige key fob is made of stainless steel and the lower part is made of an imitation black leather plastic material. The total dimension including a ring is 85 x 35 mm.

The prestige key fobs contain a EM4200 chip that was designed to replace the previous versions of EM Microelectronic-Marin chips EM4100, EM4102, EM4005, EM4105 and it works perfectly even with readers designed for its competitor’s 125 kHz TK4100 chip.

The key fobs are available in black color. By default they do not contain the numeration or other printed elements but if you need the customization, please let us know and we will send you an offer.

We can produce key fobs with printed chip ID code, and since the chip ID code can be read in more than 50 different ways, we take extra care that we print the code in the proper format. For 125 kHz chips, the usual reading format is 10-digit decimal number (8H-> 10D conversion).


Reading test for Prestige key fobs with a 125 kHz EM4200 chip

We tested the EM4200 key fobs with different kinds of readers and measured the reading distances. This is not an official test, but it was made to inform you what reading distances you may expect with your application.
 
RFID Reader Reading distance
Syris RD200-LF 5 cm
R80D 5 cm
Promag PCR 300AU-02  4 cm
Promag PCR-330A-00  3 cm
        
The reading distance between the key fob 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.
