the aircraft . That is more efficient than stand-alone systems , which the TSA employees must staff . In addition , in-line systems can process up to 500 bags an hour , compared to the 150 to 160 bags per hour processed by stand-alone machines , the TSA said . Department of Homeland Security Secretary Janet Napolitano said in a statement that DHS was able to `` stretch our resources '' by managing the recovery money and by negotiating with airports . In addition to the $ 700 million intended for checked baggage systems , $ 300 million is being allocated for checkpoint technology , such as new X-ray machines , `` whole body imaging '' technology and bottled liquid scanners .

Government auditors have long complained about existing systems , which the Transportation Security Administration rushed into place to meet congressional deadlines after the September 11 , 2001 , terrorist attacks . At airports with in-line systems , airline workers at the ticketing counters place the bags on conveyor belts , which pass through explosive detectors on their way to
