How the Seader App Works With HID SAMs and Flipper Zero

Published Nov 30, 2023 14:52 PM

While Flipper Zero (see test) has become a viral sensation, it does not work out of the box with HID's widely used SE / Seos "highly secure" credentials. However, a new app, Seader, enables working with and even exploiting those credentials on HID "standard profile" readers.

In this test, we explain how the Seader app works and leverages HID's product to decipher iClass SE and Seos credentials.
