State ID cards are issued by the same agencies as driver licenses and carry the same AAMVA barcode. Constaia reads them with the same rules, so you can accept either one in a single expect.

Pass ["us_driver_license", "us_state_id"] in expect when both are acceptable.
The REAL ID marking is returned as real_id_compliant. You do not need it for age or identity checks unless your process requires it.

What it checks

PDF417 barcode (AAMVA). The back is decoded and compared with the front.
National identifiers. Official checksum or format of the number (NIF, CPF, CURP, RUT, SSN…).us_dl, us_zip
Postal code. Postal code format of the country.
Holder. Name, number or date of birth match what you expect.
Age. Minimum or maximum age from the date of birth.
Validity. Not expired on the reference date.
Form I-9. Whether the document belongs to list A, B or C.B

FAQ

Does Constaia prove the document is authentic?

No. It checks the type, data consistency and your rules, and flags signals such as a possible edit or a screen photo. That does not prove authenticity.

Is a copy of the document kept?

No, unless you ask for it. With storage "none" (the default) the file is deleted when the analysis ends.
