bar code

The DMV has added a digital security signature to one of the two bar codes on the back of the cards.

For ticket inspections and to pass through barriers, the app will generate a bar code to scan.

Election Assistance Commission to shift its guidance on voting machines banning the use of certain bar codes and quick-response codes, has been allowed to proceed.

No more scrolling through your phone to find that bar code, or scrambling through your glove compartment to find that parking pass.

Customers use the new postboxes by scanning a bar code on the parcel and dropping it into a drawer - all powered by small solar panels on the top of the box.
