Delta rolls out facial recognition technology

Delta Air Lines has biometric self-serve bag drop-off stations.

Delta Air Lines has become the latest carrier to introduce facial recognition technology, which will match fliers with their passport photos during the self-service bag drop-off process.

The technology will debut at one of four self-serve bag drop machines at Minneapolis-St. Paul International Airport this summer and is touted as a time-saving measure for customers: Self-service drop-off stations have been shown to process up to twice as many customers per hour.
