By June 1, 2013 travelers will only see machines which have ATR that allow for faster throughput. This means faster lanes for the traveler and enhanced security. As always, use of this technology is optional, it said. According to a TSA blog posting, Congress had mandated that all TSA body scanners should be equipped with ATR by June 1, 2012. This was extended till June 1, 2013. At this point, all Millimeter wave units have been equipped with ATR, but even with the extension to 2013, Rapiscan was unable to fulfill their end of the contract and create the ATR software that would work with backscatter units.
As a result, TSA terminated the contract with Rapiscan in order to comply with the congressional mandate, it said. All Rapiscan AIT units currently operational at checkpoints around the country, as well as those stored at the TSA Logistics Center, will be removed by Rapiscan at their expense and stored until they can be redeployed to other mission priorities within the government, TSA said. Most of the backscatter units being removed will be replaced with millimeter wave units. The millimeter units will be moved from the inventory currently deployed at other airports and from an upcoming purchase of additional millimeter wave units.
