The Transportation Security Administration says it will soon begin to allow passengers to board flights by fingerprinting their boarding passes.
The agency says it plans to begin accepting biometric-based boarding passes this year for passengers traveling on Delta, American, United and Spirit flights.
The move comes as airlines continue to grapple with a growing number of people traveling by air in order to buy tickets.
The TSA announced the change in March.
The change would be implemented over the next year, the TSA said in a statement.
The process would include “receiving a fingerprint” and “checking the fingerprint against a record of previous boarding passes,” the agency said.
The new fingerprinting rules come as TSA officials grapple with an increasing number of passengers who are carrying contraband and passengers who don’t have a passport.
The Transportation Department’s inspector general last year said the agency was “in the process of making improvements to improve our screening processes.”
