It's awfully hard to read without a barcode reader. I have an "approved" ID card, and the only things on it other than typed data are two barcodes. There are no electronics.

This from the National Congress of State Legislatures discussion paper; The regulations require states to use the existing AAMVA standard 2D bar code for the machine-readable technology on the card. DHS requires that the PDF-417 2D bar code approved by AAMVA store the minimum data elements – expiration date, bearer's name, issue date, date of birth, gender, address, unique DL/ID number, DL/ID format revision date, inventory control number, and state or territory of issuance. DHS is not requiring encryption of this machine-readable information.
