"Well, we're friends! Give a friendly price! "That expression is the same as that of the obscene uncle~

Renxi smiled silently, this person is really interesting without heart and lungs! But then again, they ...... I guess it's a friend!

"Yes, how about giving you a 7% discount!"

"Good! Alas? Anyway, you didn't sell these pastries today, so what about selling them to me! When he came in, he saw the big letters on the frosted glass, and everyone could only buy one pastry. He still wants to take it back and starve those two bad friends to death!

Renxi took his ID card and began to apply for a pastry card for him, "There are so many things you can't eat alone, and it's not easy to store on this hot day." In this way, it is recommended that you buy a big cake, you can buy some sauce to go back, and it is very good to eat bread for breakfast! ”

"Dip bread and eat? I've only heard of eating it on a barbecue. But I can go back and try it~"

Wasdian took the pastry card and looked at it. The same material as the ID card, on one side is a variety of mini pastries, and on the other side is a leaf style and the word "leisure"!

"Huh? Renxi, what is this boxy thing in the middle? Alas? Here's it too! Wasdian saw that the boxy thing on the cash register was the same as the one on the card. What is it? Logo? But it's too ugly!

"You don't know? I call it a QR code! ”

"QR code? What is it for? ”

Renxi was stunned for a moment, okay! It's her overestimating the electronics here.

I have to say, sister-in-law is cool! Do you think this is a secular world that is exclusively focused on electronics?

This secular world has only recently experienced a major trauma, and whatever it is is stagnant.

The most ruthless is still country Z, whether it is the economic system or the political system has to be replaced, and it only began to develop after slowly becoming peaceful 12 years ago, especially the development of electronic products is extremely difficult......

It can be said that the current country Z is developing rapidly. But it still doesn't rank high in the world, especially economically! Because there are more people, the gap between the rich and the poor is also larger.

It's far away~

"This one is specifically for counting, and it can also be used to pay! Eh~ What are the payment methods here? ”

Hua Sidian blinked suspiciously, this girl doesn't even know what kind of payment methods there are in the world? Oh my God, I really haven't come out yet!

"Most of them are paid in cash, and a few can also be used by credit card! For example, hotels, supermarkets, large restaurants, etc. ”

Ren Xi nodded knowingly. There are only a few of them! Every time she delivers something, it's the property of her own beasts. I really don't know anything other than cash payments.

Then he began to explain the QR code, "This is the scan code payment, isn't it for you that pastry card?" The principle is similar to that of a credit card, except that you have to deposit money in the pastry card to pay. As for how to save money...... It's up to you! ”

"Oh~ But it's not much use, it's better to use a credit card!" Wasdian still can't live the benefits of this QR code.

"I'm not done yet! You can tie this card to your phone, I don't cooperate with other people's software, and later you scan this QR code to the next "Shuxian" software, and it will be tied to that software. In the future, it will be OK to pay directly by scanning the code, so that you are not afraid of forgetting to bring your credit card! ”

Renxi explained while pointing to the QR code on the cash register.
