Iris Scanners

There are two products in our IriShield™ series.

  • Wide Range of Operating Systems

    Whether you prefer a monocular device or a binocular device, the IriShield™ series has you covered. Connect these standalone iris scanners to your choice of host device. They support various operating systems such as Windows family, Linux family, WinCE, Embedded Linux and Android.

  • Flexible

    Both models in the IriShield™ series are available with USB and universal asynchronous receiver / transmitter (UART) or serial connection. The USB connection is recommended for any device that transmits data and power through a USB interface, while the UART connection is recommended for small electronic systems such as door locks.

  • Secure

    Key functions such as iris capture, iris recognition, key generation, encryption and digital signature are done on-board in a secure environment. The IriShield™ series also has its own 2048 bit RSA key securely generated on-board for encryption and digital signature creation. What’s more, it is tamper-proof, ensuring robust security for users.
