This was on another site on THT that is really alarming but you can have these cards eliminated by contacting your Senator to do away with this TWIC Card.
Senator Coleman has written a bill that would exempt folks like us from TWIC. We have been informed that the bill has finally been introduced and if passed will exempt us from the TWIC requirement as well as reimburse those who have already obtained their TWIC. There is opposition to this bill and the only way it will be adopted is if you call your Congressman and/or Senator and say you fully support Senator Coleman’s bill S.3377. They are going to vote on this before they leave session which is in the next few days so please do what you can to help get this bill passed.
