In fact, QR code technology is similar to RFID technology in that it uses frequency signals to transmit information from the scanner.
When users need to provide personal information, they only need to reach out and display the QR code, without using any special equipment for contact reading.
In this world, whether residents live in the general, special, or core areas, all have tattoo QR codes.
This solution is simple, practical, and inexpensive.
Imagine how many devices and resources would be needed to replace these QR codes with sensor chips.
QR codes, on the other hand, only require a single tattoo operation, with no additional equipment and maintenance costs.
In contrast, RFID technology requires additional RFID tags and readers, as well as associated maintenance and costs.
In this wasteland age, this extra cost can become a heavy burden.
People have to use technologies that are practical, stable, and easy to use, not technologies that seem advanced but are actually ~ not practical.
In this case, QR codes become a very practical option, seemingly backward, but able to guarantee the authenticity of the information - and cannot be tampered with.
The kind of QR code obtained through illegal means, which is not at all something that ordinary people can do, belongs to special circumstances.
For civilian technology, universality is crucial, while high-end is not necessarily necessary.
Zheng Se'e in the house heard the sound of the door, and at first thought that the courier had come to the door.
She got up and looked at the data from the gas core meter, which showed that the oxygen level was still 40%.
This is not to the point of replacing the air core!
Could it be that my sister bought the courier?
She walked to the door with doubts, but happened to see Chu Tianlan who walked into the house.
"Führer...... My lord. Zheng Se'e's beautiful eyes widened.
Chu Tianlan greeted her with a smile,
"Miss Zheng, meet again, you are very beautiful today. "
He noticed that what she was wearing today seemed to be well-dressed.
A chiffon short shirt with three-quarter sleeves, black seven-quarter wide-leg pants, slender long legs with high heels without stockings, revealing a small section of fair calves, bright ankles and instep crystal clear, snow-white and flawless, ladylike temperament is undoubtedly revealed.
When passing by her, you can still smell a faint smell of perfume, the aroma wraps around the tip of the nose, refreshing the heart.
Chu Tianlan's praise made Zheng Se'e's cheeks flush slightly, and her heart was full of joy and satisfaction.
In order to make a good impression on the Führer, she got up early this day to freshen up and change into clothes that she had only worn once on her eighteenth birthday.
Chu Tianlan didn't know about Zheng Se'e's thoughts.
He came here today because he was invited by Zheng Xue'e to discuss high-level negotiations in the security zone.
Yumi Takagi, the Terminator T-800 robot, Jung Xue'e, and Yoon Atsuki then walked into the room, while the other soldiers waited outside.
After entering the house, Chu Tianlan sat on the sofa and looked at this small residence.
This large house made of shipping containers was built according to the layout of two bedrooms and one living room.
After entering the door, there is the living room, and behind the living room is the storage room, which is where Yin April usually sleeps.
In the living room, there are two sofas around the coffee table.
The sofa is small enough to seat two people.
"Se'e, don't hurry up and get the fruit for Mr. Chu. "
"Oh! "
After being reminded by her sister, Zheng Se'e came back to her senses, walked to the kitchen, put the two apples and a banana hidden in the refrigerator on the plate, and walked to the coffee table.
"Mr. Chu, please take a seat. "
Chu Tianlan sat on the sofa to the north, and Zheng Xue'e sat on the other sofa.
At this time, Zheng Se'e also walked up with fruit.
Just as she was walking towards the coffee table, she peeked at Chu Tianlan, who was talking and laughing with her sister, lost her mind for a moment, didn't stand firm under her feet, and knocked on the coffee table without paying attention.
"Be careful. "
Chu Tianlan got up and helped her up.
"It's okay. Chu Tianlan asked with concern.
As she spoke, Chu Tianlan's scorching breath sprayed on Zheng Se'e's white and smooth face.
"It's fine. "
Zheng Se'e was ashamed, barely stood up, and was just about to walk around to pick up the fruits scattered on the ground, when there was a hot pain in her left ankle and almost fell.
"Shhh "
She gasped, and her delicate face was so painful that she almost cried.
"Be careful, sit here. "
Chu Tianlan got up and helped her sit in his place, and he sat next to Zheng Se'e, next to her.
I can only blame the sofa area for being too small!
0 begging for flowers
Yumie Takagi silently picked up the fruits and plates on the ground and walked to the kitchen.
Zheng Xue'e looked at her sister with a smile on her face.
I don't see it.,When did my innocent sister learn such a method.。
She was just thinking about what excuse she could find to create opportunities for her sister.
It seems that it is not necessary.
Zheng Se'e blushed with shame, her smart eyes turned around, but she didn't dare to look at Chu Tianlan next to her.
She really didn't mean to, today is the second time she wears high heels, and it is difficult to control her body shape as soon as she walks fast.
However, this fall was worth it.
"Sister, or else, go to the doctor's ......" (read the violent novel, go to the Feilu Novel Network!)
Before Yin April finished speaking, she was glared at fiercely by the eldest sister and immediately shut her mouth.
Only then did he remember that the Führer and his sister had important things to talk about today, and this conversation must not be known to outsiders.
Before the conversation began, Yin April saw that his sister was also sitting on the sofa, and he also wanted to sit on the sofa.
But the eldest sister alone occupies two positions, and there is no place for him!
"Sister, where am I sitting?" he asked.
"You, just stand. "
No eyes at all!
Zheng Xue'e angrily gave April a roll of her eyes.
"Oh......"
April didn't know what he said wrong, and stood aside aggrievedly.
"Hello, Mr. Chu.
I am Zheng Xue'e, a major in the Kimchi Country Command, and Yin April's sister. Zheng Xue'e introduced herself with a smile.
"I think you already know who I am, and I invite you here today.
One reason is for my younger brother April, April has a naughty personality since he was a child, and no matter how much I persuade and discipline, I can't control him.
I've always been worried about his future.
Now I am very relieved that he can do things with you.
I believe that under your guidance, April will become more mature and excellent. "
Chu Tianlan replied with a smile: "April he, he is a piece of jade that has not yet been carved, he is not bad in itself, but he lacks some guidance and tempering. "
This is true.
Chu Tianlan has seen Yin April's battles with other refugees, and he has excellent physical fitness, even surpassing some special forces, but his combat techniques are rough, and he can only use some shallow military fighting skills.
