You need another chip type for your device? Please contact us: team@metriax.de or +49 202 479 57 70.

Depending on the chip type, our Keyfobs meet the different requirements of ISO 14443 A & B, ISO 18092, ISO 15693.

Combination transponders covering different frequencies are also possible. Please contact us, we will be pleased to advise you individually!

If you not only want to read the serial number or UID of your keyfob with an RFID reader, but also display it visibly on each card, we offer you various options for this purpose:

• Laser engraving
• Digital printing
• Thermal transfer printing

On request we can also create a file with UID and serial numbers of your keyfobs. This way they can be easily added to your database, e.g. in a POS system.

Ordinary key fobs can be made by anyone! Our Epoxy RFID & NFC Keyfobs are flat, handy, durable and above all one thing: different from classic keyfobs! In the middle of this RFID & NFC keyfob is space for your design or logo. This can be printed or lasered. All color variations are possible in the print. Afterwards the keyfobs are covered with a transparent epoxy layer.

Available optionally with metal key chain or rubber band, e.g. for attachment to cell phone.
Design optionally round or oval.

Dimensions: Round: 35 mm, Oval: 52.2 x 28.1 mm.

Our tip: In combination with a logo print on reflective foil you create an eye-catching color changing effect depending on the incidence of light!

These RFID & NFC key fobs made of hand-sewn cowhide are our personal favorites when it comes to the successful mix of appearance and function! The noble, timeless design has convinced us.
Available with most common LF & HF chips, this keyfob enhances every application visually and haptically. 

Of course, individualization is also possible here, e.g. by laser engraving or embossing your logo. A serial number can also be lasered.

Available in natural brown, navy blue or pink.

Durable, robust and with a high-quality look, our metal keyfobs come along. 

Your logo and/or a serial number can be lasered or printed on request.

Available in blue and black.

In the field of ABS keyfobs, you can choose from a wide range of robust plastic products.
The keyfobs can be silkscreen printed and numbered with inkjet or laser.
Most HF and LF chip types are also possible here. 

Figure 1, model MX3: Dimensions: 40.5 x 32 x 4.2 mm, available in blue, red, yellow, green and black, among others.

Figure 2, model MX4: Dimensions: 36 x 30 x 7.4 mm, available in blue, red, black and other colors.

Your keyfob should be as thin as possible and not take up much space on your key ring? 
Then our PVC keyfobs with a thickness of only 1.2 mm are the right choice.

The laminated surface can be printed by offset or silkscreen, e.g. with your company logo. In addition, numbering of the keyfobs is possible with inkjet or laser.

Different designs possible, e.g. oval like the Epoxy Keyfob (52.2 x 28 x 1.2 mm) or fan-shaped (picture) 52.2 x 28.5 x 1.2 mm.
Available in most LF and HF variants.
