We began with a vision to create a state-of-the-art access control system utilizing PKI (Public Key Infrastructure) for secure access to computers, servers, and even physical spaces like doors. Several years ago, we developed a Java Applet for smartcards using PKI for digital signing. You can learn more about it here: Java Applet for Smartcard. Initially, these cards were mainly used for digital signatures.
Recently, we’ve taken things to the next level by updating our software with new features:
UniqueID Software
The latest version now includes two additional virtual cards:
1. Secure Card – This card works seamlessly with your mobile phone’s NFC, the secure element, and PKI.
2. Secure CardMax – Expanding on Secure Card adds biometric authentication via your mobile device for enhanced security.
We also continue to offer Physical Secure Cards with PKI for users who prefer not to rely on mobile devices for access control.
Secure Card Usage with µFR Zero Readers
Secure Card Usage with µFR Zero Readers:
When using Secure Cards with our µFR Zero readers, the functionality is intuitive:
-
For iOS devices, the reader operates as an NFC card emulator, while for Android, it works as an NFC reader.
-
The reader sends a random challenge to the phone, which signs the challenge using ECDSA (Elliptic Curve Digital Signature Algorithm) through the phone’s secure element.
-
The phone then sends both the public key and the signature back to the reader. The reader verifies the signature and checks the whitelist to grant access if the key is approved.
It’s that simple! 😊
