I did the 3 year renewal last spring (online, had to pick up the card in person). The word I got shortly after that was: you will not be required to renew your TWIC card sometime in the future, but all new captain licenses will have to have the TWIC (first time around) to be valid.
The original premise of the TWIC was to replace the ID process that the Coast Guard put you through when applying for a captains license. I was one of the lucky ones who renewed my captains license when the TWIC first came online... meaning I got to be fingerprinted and had all my personal data checked by the Coast Guard (again), THEN did exactly the same thing about a month later for the TWIC credential. What a waste of time and money.
Like everyone else, the only time I have been asked for the TWIC is when signing in for a new job (because the employer knew I was supposed to have one). When checked out by the Coast Guard at one job, I specifically asked if they needed to see the TWIC card (they did ask to see my license), and the guy said, "We don't have the readers to access the info on the chip, so, no."
In our home area, they required every 6-pack fishing guide to get a TWIC card, and those guys aren't ever going into a "secure area"... unless that's where the fish are. :wink:
It was a good premise that no one knew what to do with. At the port nearest us, truck drivers and port workers are required to have the TWIC card, also. The guy who renewed my TWIC card last time said about 80% of the cards they are issuing are not for mariners.
Another illusion of security (IMHO).
