Why Choose Our RFID Keychain for Your Business?

Built for Security & Performance

Access control that won't let people in should be in place for your business. The security chips in our keychains are widely approved and meet Common Criteria EAL4+ and financial payment standards. Attacks and unauthorised copying are stopped by multiple layers of encryption, which keeps your info safe.

A 15-centimeter distance lets you read and write. In an EEPROM, you can keep anywhere from 1KB to 72KB and more. You can use these tags in a lot of places because they can work in temperatures from -25°C to +70°C.

Durable Materials That Last

To make these keychains, we use good materials like PVC, PET, PC, and ABS. The design is strong enough to handle standard wear and tear and still work well. The money you put in is safe every year.

Plug-and-Play Compatibility

Most card readers and cash machines can read our RFID keychain without any problems. There is no need for complicated planning. They can be used without changing anything about the system.

You can use these keychains with systems that let you control who comes in and out, keep track of attendance, or make sure payments are safe.
