A cashless society means NO cash!!
Go to the ATM and withdraw the cash needed for the week, plus a bit to keep in reserve just in case. Every purchase made in shops, supermarkets, cafes etc have get into the habit of using only cash.
If you want to pay by tapping your card or your phone that is your choice, but remember that every time you pay for groceries or a cup of coffee electronically you are essentially choosing a cashless society, and if the globalists are successful in introducing this then they will have total control of your finances!!
