Product Overview
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 H10304 37-bit format. This format gives a large range of card numbers. It reduces the risk of two cards having the same number.
The card is white and printable. You can print photos, names and logos on it with an ID card printer.
