Spot,

There are various ways the TSA can focus its resources on security, outside of the encrypted bar code.

For economic resources, the bar code is really more effective as an airline revenue management tool. As airlines continue to roll out 'e-boarding pass' on Mobile Phones & PDAs, the scanners will be deployed eventually to most TSA check points and airlines will cover the expense of creating the encrypted boarding pass system, the actual costs will be minimal.

The DHS needs to refocus the role of the TSA and this new system will have its complications, but it can be a good thing if implemented correctly.
