The latest 2nd generation device firmware listed below supports SEOS cards and Elite Key. L2 does not support SEOS or Elite Key because it doesn't have a iClass model.

If you purchased a new device with the following firmware or above, it will have SEOS configured on production.
However if you have purchased a device with firmware that are lower, you will have to configure the SEOS configuration. 

SEOS configuration cards are provided by HID.

SEOS in BioStar 2.5

Although the firmware supports iClass SEOS, in order to use SEOS, you have to use a customized version of BioStar 2.4.1 because SEOS is not supported in the official release of BioStar 2 yet (current version is BioStar 2.5). It will be included in the official version of BioStar 2.6. 

Note: customized BioStar 2 versions cannot be upgraded to future official versions.

SEOS with Elite Key
The Elite Key is stored in the SAM so it will remain even if you factory reset the device or do a firmware upgrade. 

If you want it to read other HID card PACS Data again you will have to restore it with a Standard Key Card. 

Mifare and Desfire cards (CSN and smart card information) can always be used regardless of the Elite Key. 

SEOS Card Smart Card Support

Not all SEOS cards are support biometric data storage. Check your card type before attempting to write a fingerprint template on the card. 

SEOS cards supporting biometric data is HID iClass Seos Cards with the embedded solutionSuch card numbers are named with "-ES".

The card should have a ADF and a Global Key

 (e.g. Seos 8K + Prox = Part Number 5106RGGMNM-ES)

Reading SEOS PAC Data

Your device does not need the SEOS configuration with the configuration card to read PAC Data. However if you're trying to read/write a smart card, you will need the SEOS configuration.
