Elon Musk wrote in a post that when shopping, a user simply needs to take a photo of their credit card and send it into the chat box, and the Grok bot will search the entire web for the best price on the desired item and complete the order.

In response, OpenAI executive Tibo replied, "Then I might as well just put my card right here." At the same time, he posted a photo of a fictional credit card, hinting at the security risks of the feature. The cardholder name on the card is the poster himself, THIBAULT SOTTIAUX, while "NOVA" is merely a fictional card face identifier on this prop card.

In addition, some netizens said that Amazon.com (AMZN) has begun blocking Grok's access. Musk replied, "Grok will find another way to complete the shopping. I just placed an order for Lego, and Grok completed the purchase directly from Lego's official website."
