While he was hesitating, the cashier had already completed the payment by scanning the code swiftly.

Seeing this, he had no choice but to scan his face to pay.

Pushing the cart, we came to the underground parking lot.

After making sure there was no one else around, Empress Changsun said nervously, "Xiao Yu, didn't we pay just now? If you don't have any money, I can ask Erlang to prepare some for you. There's really no need to run away..."

Zhou Yu: (°ー°〃)

"Why do you say that, sister-in-law?"

Zhou Yu looked puzzled, then said firmly, "We've already paid for these things."

"How is that possible? You didn't even take out your phone just now."

Empress Changsun didn't believe it at all.

She saw it clearly when Zhou Yu paid the money before.

First take out your mobile phone and scan the green or blue code given by the merchant, and then the payment will be successful.

She saw it clearly just now, so how could she believe Zhou Yu's words?

After hearing what Empress Changsun said, Zhou Yu finally understood what she was worried about.

He first quietly hid the "baby-eliminating device" in his pocket, and then explained, "There are many ways to pay now, such as cash, automatic code scanning, facial recognition, and palm print recognition."

"Before, when I was at the children's park and the clothing store, I just chose to scan the code to pay because I happened to have my phone with me."

"Just now at the supermarket checkout, because my phone was in my pocket, I chose facial payment."

Zhou Yu explained it in great detail.

Even what is paper money and what is digital currency are explained in depth and in a simple and easy-to-understand way.

Empress Changsun was amazed when she heard this.

Just when Zhou Yu thought that the matter was over.

Li Lizhi, who was standing next to him, pointed at his pocket with curiosity and asked, "What was that thing you just hid in your pocket?"
