What is the new head of the Transportation Security Administration going to do now that he’s been on the job for four weeks?

Withing 60 days he’s going to make sure all airport screeners are retrained so they can better detect explosives and spot weapons. And he’s going to try to get more passengers to enroll in the agency’s expedited security checkpoint program, called pre-check.

He’d also like to get rid of boarding passes and someday replace them with biometric technology.

Peter Neffenger, the new TSA administrator, went before the House Homeland Security Committee on Wednesday and said it was a “huge concern” that the agency’s officers failed to identify bombs, weapons and other security threats 96 percent of the time during recent undercover testing.

“It greatly disturbs me to know that we had that failure rate at the checkpoint,” he said, and to fix that, the agency will “train out those failures.”

Neffenger also told the panel he wants to increase the use of explosive-detection dogs for passenger screening, expand enrollments in the Pre-check program and phase out “managed inclusion.”

Neffenger said that likes the idea that biometrics – individual characteristics such as fingerprints or facial characteristics for personal identification – might someday mean that “you are your boarding pass.”
