Republican presidential candidate and senator Ted Cruz has pledged a biometric entry and exit system to track visa holders should he get into power.Speaking last week, Cruz said one of his priorities would be to finish the biometric tracking system at our nation's ports of entry.”Amazon and FedEx can track packages around the world with down-to-the-minute precision. Google can provide street-view maps of almost any address in the country. It is unacceptable that our federal government cannot keep track of the foreign nationals who have entered the United States, particularly when millions of illegal immigrants currently in the United States entered legally but overstayed their visas – as several of the 9/11 hijackers had done.” Cruz said it was “past time” for the federal government to fully implement a biometric tracking system so that authorities have full awareness of who is on American soil at all times.”Since 1996, Congress has 'required' full implementation of an entry-exit system at all of our ports of entry, yet multiple administrations, both Democrat and Republican, have refused to follow that law. In the first 100 days of a Cruz Administration, those who have broken the law will be held accountable, regulations that stand in the way of finishing the system will be eliminated, and the Department of Homeland Security (DHS) will complete implementation by the end of my first year in office”.He also pledged to strengthen E-Verify. E-Verify – a federal digital identity program that lets employers verify the legal status of job applicants. He pledge to treat E-Verify as a national security tool: Push to have E-Verify both permanently reauthorized in statute and deemed an essential national security screening tool, to ensure that it operates in the event of a lapse in funding.In July, the US Customs and Border Protection (CBP) has revealed that it will pilot the collection of biometric and biographic information on selected flights from up to 10 identified US airports over the next year. In a notice published in the Federal Register, the CBP revealed that the programme will be called the “Be-Mobile Air Test”.The test will be rolled out over this one-year period at Los Angeles International Airport, Los Angeles, California; San Francisco International Airport, San Francisco, California; Miami International Airport, Miami, Florida; Hartsfield-Jackson Atlanta International Airport, Atlanta, Georgia. The list also includes Chicago O'Hare International Airport, Chicago, Illinois; Newark Liberty International Airport, Newark, New Jersey; John F. Kennedy International Airport, Jamaica, New York; Dallas Fort Worth International Airport, Dallas, Texas; George Bush Intercontinental Airport, Houston, Texas; and Washington Dulles International Airport, Sterling, Virginia.The CBP says its BE-Mobile Air Test is designed to test both a new biometric exit concept of operations at selected airports with CBP officers using a wireless handheld device at the departure gate to collect biometric and biographic data and CBP's outbound enforcement policies and workforce distribution procedures.
