I'm asking because I know many people, myself included, who use our passport or Global Entry, Nexus, or passport cards as ID at the checkpoints because we do not want to show an ID that includes our home address. These documents do not have barcodes, although they do have machine-readable strips (MRZs).
Well, it's brand new bio fingerprints technology. You can wave with your fingers. They will have your background checks. If you go through PreCheck. You don't have to show your BP to TSO. You still required show your ID.
