I'm new to the TR program and just recently signed up. But I noticed when I used my TR card at Harrah's San Diego in the kiosk where I swiped my card for a free buffet dinner the kiosk didn't require my PIN and it automatically printed out a voucher with my name on it for the free buffet. I figured okay since it has my name on the voucher and when I go to use the voucher at the buffet that the cashier will check my ID to make certain that my ID matches the name on the voucher. I was surprised that the cashier didn't check my ID and allowed me into the buffet. Does Total Rewards print out these vouchers without requiring a PIN? It concerns me because if I misplace my TR card someone can then print my voucher and use my vouchers at will.
