Global Entry is expanding in a big way in 2020. Global Entry is also going the high-tech route this year. The popular program just added face-scanning technology at 15 airports around the country. Popular hubs like New York (JFK), Miami (MIA), Houston (IAH), Newark (EWR), Orlando (MCO), Philadelphia (PHL), Detroit (DTW), Dallas/Forth Worth (DFW) and San Diego (SAN) are now offering facial scans to members of the Global Entry program.

Travelers with Global Entry memberships have traditionally been required to scan both their passports and fingerprints. Hubs that are using face-recognition technology are allowing members to skip those steps. Travelers can now simply have their pictures scanned before waiting for a printout that can be handed to an agent. The process is quick and seamless.

Of course, not everybody is thrilled to hear about the new technology that's being implemented around the country. Global Entry's technology uses scans and pictures from government databases to match the facial scans of passengers. Privacy advocates are growing increasingly concerned with the way government agencies are handling and storing photos of citizens.

Several international airports are also making it possible for American passengers to enjoy face-recognition technology when traveling. These airports have entered into pre-clearance agreements with U.S. Customs and Border Protection to create seamless experiences for American travelers. The four airports that are offering this technology on an international basis are Aruba's Queen Beatrix International Airport, Nassau's Sir Lynden Pindling International Airport, Ireland's Dublin Airport and Ireland's Shannon Airport.

The list of airports using face-recognition technology to speed things up will only grow as we get deeper into 2020. Most frequent travelers like this new development because it helps to cut down on delays that can be caused by snaking security lines. However, both travelers and privacy advocates have understandable reservations when it comes to the growing use of biometric screening at airports around the world.
