Not really. First I do not think that this will improve anything.I have yet to go through a boarding line without at least one boarding pass being problematic. Now we are going to add the issue of cell phones, cell phone carriers, transmissions in airports, etc. That is simply going to create delay and not stop fraud because the clever person (I am not one of them) can find ways to simulate the code. In addition, the airport is a secure area. No one gets a boarding pass without displaying appropriate ID so why should the money be spent to solve this "problem". Seems like a nonproblem to me. There are far more serious security issues with flying than this one.
