Good credit/debit card option for my cognitively declining father.

Hello,

So long story short, my father is very disabled and is in a cognitive decline. He also lives separately from my mom in an assisted living facility. We have had to cut him off financially because he was starting to use his CC very irresponsibly. The issue is he has been harassing his caretaker and my mom (who is now in charge of all their finances) to take him to the bank to open a new account and its causing a lot of grief and family drama.

I want to find a way to give him a sense of financial freedom back that we can monitor.

My first thought it to either open him a new joint checking account that we can monitor or possibly a secured credit card. But was wondering if their are any other solutions out there that make more sense for our situation?
