Seos is HID’s most secure card technology. It protects your identity data with strong, modern encryption. No traceable data is shared when the card is read. This stops the card from being copied or cloned.
The card uses HID’s Secure Identity Object (SIO) model. This adds extra layers of security on top of the chip itself. Your data stays safe even if one layer is attacked.
The card comes ready to use in the H10301 26-bit format. This is the industry’s standard open format. Almost every access control panel supports it. It is a good choice when you upgrade from old proximity cards and keep your current system.
The card is white and printable. You can print photos, names and logos on it with an ID card printer.
