Btw, I did just a little research on this one before answering, and recieved my answer from an attorney just this eve. If the law allows the police to ask you for your identity, by extension they are allowed to verify said identity. The overly literal reading of the law that you need only state your identity, not prove it would be thrown out of any court of law in short order. To quote the attorney friend I spoked with, “The law sometimes lacks common sense, but it hasn’t deserted it entirely.”
Is said attorney referring to Ohio law? It explicitly forbade requiring ID, it wasn't implied. Not every state has such a law.
Sorry, didn’t mean to say it forbade requiring ID itself, but any information beyond what is in the law. Any reasonable person must agree that an ID is much more information than name, address and DOB, and thus more information than the law allows.
