Yeah, those help. But they appear to be as useful as sigs. My next door neighbor had her purse with checkbook and credit cards stolen out of her car in her garage by what turned out to be a grifter couple, albeit dumb ones. My neighbors name was very feminine. The guy used one of her checks to buy a set of tires, actually wrote his real name and address on the order sheet at the tire place, then crossed them out (though you could still read them) and wrote her name and address next to them. They took this without question, and her check.
The dudes wife went on a shopping spree through over a dozen stores with my neighbors credit card which featured a photo. She was a tall, heavy black woman. My neighbor was a short petite white woman with blonde hair.
They were eventually caught when the police simply went to the address that the guy had written on the tire order form, which was still completely visible. Couple had an arrest record a mile long and had been in and out of jail on petty items like this all their lives.
