Check Which Card Will Pay Before You Approve a Purchase

Before a muse pays for anything, it shows you the purchase and the card that will pay for it, and it waits. Your job at that moment is to check the card by name, not just by its last four numbers, because a card saved for medical costs can sit in the same wallet as your everyday card.

What it does

When you connect cards for shopping, they sit together in one wallet, even when they are meant for very different things. A debit card, a credit card, and a health savings account card can all appear as choices at checkout. The muse builds the order, brings it to you for approval, and names the card it plans to use. Nothing is charged until you confirm. At the payment step it stops and waits. That stop matters, because one of the cards on offer can be tied to a health savings account, which should only pay for medical costs. Because the order waits for approval, no charge goes through on the wrong card until you say so.

How to use it

1. Before your first purchase, look at every card saved in the wallet and name each one: everyday spending, bills only, medical only.
2. Remove any card you never want used for general shopping, especially health savings and flexible spending cards.
3. When an order comes to you for approval, read three things before you tap: the items, the total, and the full name of the card that will pay.
4. If the card name does not match the kind of purchase, stop and switch it. Approving the total is not the same step as choosing the card, and both need your eyes.
5. After the purchase, check the receipt and confirm the charge landed on the card you picked.

What you need

• Your cards connected for shopping, with approval turned on for every purchase
• A minute to read the approval screen in full, every time

What to watch for

• Last four numbers are easy to misread, especially after a bank sends a replacement card. The card name and the account behind it are what matter.
• A health savings card can be accepted at a register and still be the wrong choice. Using it for non-medical spending can create tax problems later.
• Familiarity is the risk. The first approval gets read carefully and the twentieth often does not. Treat every approval screen as the first one.
