Banks eye single-purpose digital tokens to let AI shop safely for you

Banks and card issuers have a way to let an AI assistant shop for you without handing it your real card number. According to a PYMNTS Intelligence report, the tool is a digital token that limits what the assistant is allowed to buy. A grocery token, for example, would not work for anything else.

What changed

The report is called "When Fraud Becomes the Customer: The Next Battlefront for Issuers." It is the September edition of the Payments Innovation Tracker Series. It says AI agents, meaning software that can act for you, are starting to shop on behalf of customers. A token is a substitute for a card number. It can spell out what the customer has agreed to pay for.

Why banks are paying attention

Criminals can now use AI to copy a customer's voice, face and even typing rhythm. That makes it harder for a bank to rely on one check at login or checkout. The report also put numbers on the cost of fraud to banks beyond stolen money.

• Half of financial institutions said fraud had damaged customer loyalty.
• 44% said fraud had harmed their brand or reputation.

What banks already have

Many institutions already have tools to build on, including identity checks inside their banking apps. The report says pairing those checks with a token that carries the customer's spending instructions lets banks support this new way of shopping while the customer stays in control of the purchase.

What is not known yet

The article does not name any bank that offers these tokens today. It also does not say when shoppers can expect them or how they would be set up. The full report sits behind a sign-up form, so those details are not in the material available here.

What to do

If you plan to let an AI assistant shop for you, ask your bank whether it uses limited tokens instead of sharing your real card number. The goal is simple: if the assistant is ever compromised, the token should be useless for anything you did not approve.
