Is there a threat from skimming personal information or tracking American citizens?
The RFID technology used in the passport card will enable the card to be read at a distance by an authorized CBP reader mounted alongside the traffic lane. The chip contains no biographic data as is the case with the e-passport. The chip will have a unique number linking the card to a secure database maintained by DHS and State. However, to address concerns that passport card bearers can be tracked by this technology, we are requiring that the vendor provide a sleeve that will prevent the card from being read while inside it.
