Reload, Re-Fill, Add Funds/Money/Cash
Definitely not top-up.
Pot should be bucket or jar. Standing-Order is not a term known to Americans. Auto-Pay might me more familiar.
Direct Debit is not used, this is usually also branded auto-pay.
Direct Deposit is used for salaries / wages.
Chip&PIN is not used, but “PIN Debit”
“Credit Debit” would be signature debit used over the MasterCard Credit Card network.
Checking Account is what one would call a Current Account.
Banker would be Teller.
Pay-In would be deposit.
Till would be checkout.
Contactless would be Tap-To-Pay
