Dad soon entering into memory care facility. They said that he cannot carry a wallet, money or ID. Any advice?

Agree about keeping an empty wallet without valuables. I used to put money in my dad's drawer and he would watch me do it, then I would take it before I left without him seeing me. He forgot and we did the same routine each time I visited.

Let him keep the wallet, and a few pictures in it, with his name and room number in it. Nothing of value, please.

Plus if he plays Bingo, they will give him "Gold" coins. My mother just loves these 'gold' coins and stashes them in her eyeglass case which she keeps near her.

I mean, gees, what else could any person want? :)

Yes, it's a liability thing and facilities advise against carrying a wallet and/or money. Residents don't really need money in a wallet in their pocket once they're living there.

When my dad went into a nursing home he was very uncomfortable not carrying a wallet so I gave him his wallet minus anything he couldn't afford to lose and I tucked a $10 bill in there to make him happy. He had been there less than 5 hours when I got a call from him that he had lost his wallet and that money. From then on he didn't carry a wallet and I'd only give him a few dollar bills to carry with him (which always ended up lost). I never gave him more money than he could afford to lose but having some money on him made him feel better. It was a waste of money since it always got lost but my dad felt better having it on him.

Yes, its a liability problem. Let him know he can keep his essentials in the drawer? I know these things are difficult but probably the least of your worries at this point.
Possibly ask about an empty wallet if he throws a fit?
