It's pretty time consuming to obtain ID's for every contractor that comes through the door. One is usually expected to have their own ID when doing contracting. If you are going to do ferry work or any other contracting, please do yourself and any future clients a favor and obtain your own ID, and don't leave home without it. At some airports it is imperative that one has an ID or they won't be granted access to the ramp. IBAC is one company that provides ID services as well as Universal (if you have an account with them.)
