Convenient login via Bittron hardware USB key

Bittron is a unique link between our developed hardware key and mobile application. It allows for secure multifactor logins to computers and electronic services. It offers the same possibilities as a PKI smart card (i.e. it contains a qualified QSCD chip) – it creates a qualified electronic signature, etc., but increases the security level.


Bittron is a secure hardware key (a USB token with an embedded chip) for access protection to computers, networks and online services.

It is linked to a mobile application that serves as a security component (activation, login), and terminates the connection when the user moves away from the computer.

It communicates with certificate administration modules and can easily be incorporated into the ecosystem of other tools within the ProID platform.

A revolutionary way to log in to computers and systems

ProID Bittron is our own unique solution, which we’ve developed as a substitute to readers and smart cards. It is a hardware USB key with a built-in independent chip.

Bittron is accompanied by the user mobile application. This authenticates its log in – in the application, a PIN or biometric data (fingerprint) must be entered to confirm login via Bittron. If the user moves away from the connected device (i.e. leaves the work space), Bittron automatically terminates the connection.
