<prompt> Human: Sometimes when I deposit a check at my local credit union the teller will write CT on the front of my check. The amount is usually around 800-900 or so? What does this stand for?UpdateI am an idiot. I guess it was TC and it stands for True Check which is a fraud screening program that my credit union uses to verify large checks. Apparently all I had to do was ask my bank what TC stands for they they will just tell me! WHO KNEW!UPDATE 2 None of yall motherfukers was right anyways but thanks for trying  <response>: Connecticut.
