Enhanced Drivers Licenses: What Are They?
i know this is old, but just found out about it
State-issued enhanced drivers licenses (EDLs) provide proof of identity and U.S. citizenship, are issued in a secure process, and include technology that makes travel easier. They provide travelers with a low-cost, convenient alternative for entering the United States from Canada, Mexico or the Caribbean through a land or sea port of entry, in addition to serving as a permit to drive.
The Department has been working with states to enhance their drivers licenses and identification documents to comply with travel rules under the Western Hemisphere Travel Initiative (WHTI), effective June 1, 2009.
Enhanced drivers licenses make it easier for U.S. citizens to cross the border into the United States because they include
a vicinity Radio Frequency Identification (RFID) chip that will signal a secure system to pull up your biographic and biometric data for the CBP officer as you approach the border inspection booth, and a Machine Readable Zone (MRZ) or barcode that the CBP officer can read electronically if RFID isn't available.
