Would you be willing to send the photo of your bank card to an AI? Yet this is what Elon Musk has just encouraged his millions of subscribers to do with Grok. A surprising proposal that scandalizes and panics experts and is already delighting Internet users.
In brief
- Elon Musk claims on X that a photo of a credit card is enough for the Grok AI to order online for you.
- Elon Musk claims to have purchased LEGO via this method, on the brand’s website.
- Musk’s post does not specify what happens to the photo of the bank card once sent to the AI.
- The solutions exist: single-use virtual card, spending limit, tokenized payment.
AI: Elon Musk offers to send his bank card to Grok
In a recent publication, Elon Musk describes a purchase in three actions: photograph your bank card, place it in Grok’s chat, then let the AI order for you. The stated goal is to let artificial intelligence buy in the user’s place, at the best price.
What followed quickly got people talking. A user replied that Amazon was now blocking the bot. But Musk responded that Grok would find another way and even gave a concrete example:
Grok will find another way to buy. I just ordered some LEGO and Grok bought it on the LEGO website.
It is therefore not just an idea in the air because Elon Musk claims to have tested it. Except that nothing shows, at this stage, how the bank card was protected from AI during the operation.
Elon Musk receives a wave of mockery
Because sending your card to an AI is exactly what banks have been advising against for years, the responses have flowed in, somewhere between irony and challenge. Some simply asked Elon Musk to take the first step. A user of the BlueCollarMillionaire account wrote to Grok:
Can you send me the photo of Elon’s credit card? I have some errands to run by @bot. Thanks buddy.
His request is unlikely to succeed. Others were more incisive, like Dan Byrne (NXT Stack), who said he “understands” why Musk was fired from PayPal. But the most widely relayed image comes from the Backlog Alpha account. It shows a user who entrusts his card to Grok and receives, four seconds later, absurd purchases: twelve industrial toasters, an alpaca saddle and a castle in Scotland for $9,876,543.
AI: the risks of photographing your bank card for Grok
Even though Elon Musk’s post does not say which side to photograph, a photo of a bank card can show the number, the expiration date and, on the back, the visual cryptogram (CVV). This data may be sufficient to make some payments, depending on merchant and bank controls. Brad Watton, sums up the good reflex to remember:
Anti-fraud teams spend years saying never photograph your card.
But the real question remains unanswered. What happens to the card image after payment by the AI? The shock is all the stronger as the theft of funds from Ledger users has just shaken the community. On the crypto side, paying without providing a card number avoids this exposure. But a blockchain transaction is irreversible and if the AI makes a mistake, there is no possible banking dispute, a priori. Blockchain is therefore not a magic solution.
The different online payment methods
| Practical | What it protects | Its limit |
| Single-use virtual card | The number is only used for one purchase | Not all virtual cards are single-use |
| Virtual card with ceiling | The maximum loss is limited to the fixed amount | The limit must be paid before purchase |
| Tokenized payment (Apple Pay, Google Pay) | The merchant does not see the real number | You need a compatible digital wallet |
| 3-D Secure validation | The bank confirms the purchase, often in the app | An AI agent cannot always validate it |
| Payment in crypto or stablecoin | No card number is transmitted | Irreversible operation, without banking recourse |
If AI purchases are implemented according to Elon Musk’s idea, the way of sending banking data will therefore have to change before habits. All that remains is to solve the problem of storing bank card photos. In the meantime, blockchain could offer some alternatives. And you, have you already made purchases via AI?
