We will need a replacement for cash money. Develop a “money card” not like a debit or credit card but that can be used as one uses cash from his wallet. It would be a thin card that displays on its face the money content.
You put money in it as you do today to put money in your wallet. You go to the bank, and ATM, or money card web site site that is linked to your bank account..
You use it like cash by presenting it to a store pay machine. Because it is only money it does not have any link to the owner, no photo, no ID number, no password. It is only money.
