Tang Xin didn't rush to start the car, but said with interest: "Let's talk about it." ”

Song Qian said succinctly: "Offline transactions, our traditional form is POS machine card and cash payment, and QR code payment, for consumers is first of all very convenient to carry, just a smart phone can complete all operations, no need to carry bank cards and cash, for merchants can also save the time cost of collection and equipment costs, originally need to configure POS machine or campus card machine, now print a QR code can be used to collect money, it can be said that it is not too convenient, Not to mention transactions on other levels, which can be replaced with QR code payments. ”

"However, the first problem exposed by QR code payment is the need to rely on smart phones, which limits the use of QR code payment to the user group of smart phones, college students will basically have a smart phone at home, but minors, middle-aged and elderly groups, in the use of preferences are also based on PHS and other cheap mobile phones, the popularity of smart phones at these levels is not high, and even supermarket shopping, the use of POS machine card is their more inclined approach, this is a problem."

"Another question." Song Qian said quite seriously: "Security, security is the inevitable problem of QR code payment, compared with the bank card with a perfect security system, the QR code payment lacks a complete set of standardized specifications, and the entire payment model lacks a system, which will produce a lot of regulatory loopholes, resulting in policy security risks, and the same, it is also easy to be used to carry out illegal activities, resulting in payment risks, which is the first problem to consider, after all, there is only one QR code, who knows what this content is before scanning the code, There's so much to do. ”

As a top student of Shuimu University, Song Qian's questions hit the nail on the head, and it was obvious that she had done her homework before the investigation.

Tang Xin nodded with satisfaction: "Xiao Qian, you see it very well, to be honest, this is why we came to investigate, but Xiao Zhou is right about one thing." ”

Tang Xin paused, took a sip of tea, and continued: "The licensing fee of the sweep patent is only high, not low, in other words, this patent is absolutely epoch-making. ”

"Yes, Sister Xin, the system can not be explored and established, there are security risks that can be strengthened, and smartphones will soon be able to eliminate the older generation of machines and become the mainstream, but it will take time." Song Qian said quite seriously.

That's the obvious problem, but it's time to fix it.

But in the same way, time is also the most unsolvable problem.

The risks associated with rushing to implement a new payment method are really worth considering.

Tang Xin thought for a while and said softly: "At least we still got satisfactory results in this investigation, that's enough, we don't need to consider the issue of security risks, Xiaoqian, you go back today to write a report, I think the line will pay enough attention." ”

"Okay, Sister Xin."

...

HONG Da,

"Zhou Yan, to be honest, I'm a little apprehensive."

Zhou Wan and Zhou Yan walked side by side on the tree-shaded path, and she opened her mouth to break the silence.

"What's there to worry about?" Zhou Yan asked.

"The project is very good, but there are too many things involved, and I'm afraid I won't be able to do it well." Zhou Wan said softly, her tone also revealing a little uneasiness and hesitation.

It is true that the prospect of sweeping the patent is very good, but it is because it is too good, but it makes Zhou Wan a little less confident.

Especially this time the bank came to investigate, Zhou Wan can know the importance of sweeping the project from Zhou Yan's conversation.

Hongcheng code chain technology, build a sweeping patent ecology, from catering, transportation, shopping and other aspects, but looking back, there are really too many things to do, even if Zhou Wan has the confidence and energy to deal with it, at this time there will be a little more powerlessness.

She's afraid of messing up.

"Isn't that me?" Zhou Yan said softly.

Zhou Wan was stunned for a moment, she always felt that this sound a little weird.

"Xiaowan, we are friends, we are partners, I can't let you resist in the front, I am lazy in the back, that is really a black-hearted boss." Zhou Yan shrugged his shoulders and said.

Listening to Zhou Yan's rather casual words, Zhou Wan suddenly had something called peace of mind.

He's not going to leave it at that.

However, Zhou Wan still said in a low voice: "You have long been a black-hearted boss." ”

Even she didn't realize that the tone of talking to Zhou Yan was a little ambiguous, not the tone that a teacher, a senior sister, or a friend should have.

Zhou Yan listened to Zhou Wan's similar coquettish complaints, and his heart trembled, and the senior sister suddenly spoke in such a tone, as if he could withstand it, he said half-jokingly: "Xiaowan, I don't care enough about you, let you have this kind of wrong cognition." ”

"Go."

Zhou Wan flicked Zhou Yan's head, causing the latter to groan, Zhou Wan said angrily: "Xiaowan Xiaowan Xiaowan is still addicted, it's not big or small, and it's weird to talk." ”

Zhou Yan simply stopped talking and looked at Zhou Wan directly.

It was rare to see Zhou Yan like this, and Zhou Wan was also amused, "What are you doing?" ”

"It's nothing, don't shout anymore."

Zhou Yan didn't care about Zhou Wan, and walked forward with his hands behind his back.

Anyone with a discerning eye can see that he is playing with his temper.

Zhou Wan followed, walked side by side with Zhou Yan, and said with a smile: "Is Xiao Zhou angry?" ”

Zhou Yan did not speak.

Zhou Wan somehow, subconsciously reached out and pulled Zhou Yan's arm: "Okay, okay, don't be depressed, you can shout." ”

Even she didn't realize that her actions were a little intimate.

"I'm not depressed." Zhou Yan glared at Zhou Wan.

What to say.

Does he seem like a depressed person?

But falling into Zhou Wan's eyes is another meaning, Zhou Wan actually thinks that Zhou Yan, who is so fierce now, is a little cute.

She quipped: "It's so stingy, you didn't say anything about my jokes, don't you really shout when you don't shout, why haven't I seen you so obedient before." ”

"Don't shout, it's boring." Zhou Yan said speechlessly.

"Then call Senior Sister, I was originally your Senior Sister." Zhou Wan was afraid that Zhou Yan would really be angry, so she said softly.

"Senpai."

"Hmm."

"Senpai."

"Hmm."

"Senior sister?"

"Why do you keep shouting?" Zhou Wan said angrily.

"It's nothing, it's a bit boring." Zhou Yan said.

"I also find our conversation a bit boring."

Zhou Wan didn't know what was wrong with her today, and her mood was a little wrong, anyway, she was affected by the boy in front of her.

And he didn't go to work when he had a good time, and had a strange chat with Zhou Yan on the road.

The key is that I seem to be quite willing.

At this time, a girl from the student union came up to me.

Zhou Wan knew that it was a ministry of the secretariat, and apparently the girls in the student union also saw her and Zhou Yan.

Zhou Wan actually had the idea of wanting to flee immediately, but Zhou Yan kept moving forward, and she had no choice but to follow.

"Sister Wan!" The girl knew that Zhou Wan was the former president of the student union, and she was so eager to say hello.

Of course, she also noticed Zhou Yan, but the girl obviously didn't have much impression of Zhou Yan.

It's just that her expression has betrayed her, obviously she was a little surprised to see Zhou Wan and Zhou Yan walking together, secretly guessing Zhou Yan's identity.

"Hello." Zhou Wan was a little nervous for a while, not knowing what the girl's name was, so she just replied perfunctorily.

"Sister Wan, you're busy, you're busy." The girl smiled and said, with a 'I understand' expression.

Zhou Wan was a little unnatural, she felt that the girl had misunderstood something.

In particular, the girl left directly and did not continue to communicate with her, which made her even more unnatural.

She has always been calm, but she is a little less calm at this time.

Zhou Yan still didn't say anything, walking by herself, Zhou Wan pursed her mouth, she felt that she was really not normal today.

Especially the face is hot, as if I have a fever.

She even felt that the wind was cold, and she just wanted to finish this somewhat painful trail quickly.

"Senior sister, what's wrong with you?" Zhou Yan turned his head sideways to look at Zhou Wan, he felt that Zhou Wan's state was a little weird.

The girl who walked over to the student union just now, if it was Zhou Wan before, would definitely not behave as unnaturally as just now.

Even now he is walking more quickly than he is.

"It's fine." Zhou Wan felt a little repulsed by Zhou Yan calling herself senior sister, and she didn't know what was wrong.

Zhou Yan noticed that Zhou Wan's face was a little ruddy, like a girl like a white paper when she was shy, but Zhou Yan knew that Zhou Wan was never shy, but the way she blushed now can really fascinate people.

Especially the eyes that are not firm enough to dodge, the head that is slightly lowered, and a few strands of hair that fall mischievously on the forehead, I have to say that Zhou Yan feels that the current Zhou Wan is more moving than before.

"I see senior sister, your face is quite red, it can't be some kind of illness." Zhou Yan asked.

"You're sick." Zhou Wan glared at Zhou Yan, as if to hide her unnaturalness, and added: "Don't be suspicious." ”

"Okay, senior sister."

Zhou Wan felt that Zhou Yan was absolutely intentional when she spoke like this, and she said a little angrily: "Don't call me senior sister!" ”

Zhou Yan felt that it was really interesting to make Zhou Wan lose his temper, and he smiled and quipped: "Then what are you called?" Schoolgirl? ”

Zhou Wan confirmed and affirmed that Zhou Yan was angry with her this time, and she said with annoyance: "Whatever you want." ”

She felt that she was not in the right state, that it was really wrong.

But I can't tell what's wrong.

In the end, he walked a little depressed and didn't say anything.

The entrepreneurial base is not far away, so the two of them quickly arrived downstairs, and they don't know who is angry or who makes who depressed, and they haven't spoken since then.

"I'm leaving." Zhou Wan said.

"Okay, senior sister." Zhou Yan said.

Zhou Wan glared at Zhou Yan, but she finally didn't defend against Zhou Yan, she broke the defense, she puffed out her mouth, and went upstairs by herself with some forks.

"Alas, woman."

Zhou Yan looked at Zhou Wan's beautiful back and sighed faintly.

...

"Sister Wan, what's wrong with you?" Gu Tian has been in the office, and she couldn't help but ask when she saw Zhou Wan's sullen appearance since she came in.

Zhou Wan shook her head lightly: "It's nothing, I'm angry with someone." ”

"Who's going to be mad at you?" Gu Tian also had some gossip.

She always felt that Zhou Wan's current state was a bit weird.

"A nasty boy." Zhou Wan's tone was a little resentful.

Obviously, it was originally good, but how did it change its taste, in fact, Zhou Wan didn't know what the reason was.

She could only blame Zhou Yan for deliberately being angry with her.

And when Gu Tian heard Zhou Wan's words at this time, her mouth opened slightly, as if she had heard something incredible.

"Sister Wan, what's hateful? What boys? Gu Tian asked blankly.

"It's nothing, it's just that it feels so messy and annoying right now." Zhou Wan complained to Gu Tian for the first time.

Amazing!

Gu Tian looked at Zhou Wan again with a scrutinizing look, and her mouth was tsk.

"Xiao Tian, what are you doing?" Zhou Wan was a little unnatural by Gu Tian, and couldn't help asking.

Gu Tian was quite serious at this time, and her little face was upright, "Sister Wan, you recruited from the truth, are you in love?" ”

However, her voice was very small, obviously she was also worried about the other members of the office, or Zhou Wan's feelings, and she was silent.

"No, don't talk nonsense." Zhou Wan hurriedly waved her hand.

Gu Tianhu said suspiciously: "Then why are you so strange now?" What other hateful boys, tell me who this hateful boy is! ”

Zhou Wan couldn't say that Zhou Yan made herself angry, she could only say: "Okay, don't ask, there's really nothing." ”

"Today I met with the bank's investigators, and then I may be able to cooperate with the bank in the project, Xiao Tian, your task is heavier, don't gossip about what you have." Zhou Wan added quite seriously.

It's just that Gu Tian didn't eat Zhou Wan's set at all, she muttered dissatisfiedly: "Put aside the project matters first, Sister Wan, hurry up and recruit from the truth, don't think about getting by, and when you meet the boys you like, it's almost like you, I've seen a lot!" ”

"Whoever likes it, don't talk nonsense." Zhou Wan was anxious.

And seeing that Zhou Wan was in a hurry, the more Gu Tian succeeded, she said with a smile: "Explanation is a cover-up, cover-up is the truth, let's talk quickly, which boy has entered the eyes of our president?" ”

Zhou Wan felt that she couldn't pass this level today, and Gu Tian obviously misunderstood.

She took a deep breath, and simply pushed the boat down the river and said directly: "Then Xiao Tian, you can help me with the staff officer, that boy." ”

She bit the word boy hard.

Gu Tianle was happy, she rubbed her little hands excitedly, and didn't care about the code being written in front of the computer, "It's easy to say, I'm very experienced in this area." ”

"Then let me ask you, if a boy deliberately makes you angry and makes you uncomfortable, what does that mean?" Zhou Wan asked quite seriously.

"It means that I have a good impression of you and like you, isn't this something that can be seen very easily?" Gu Tian said indifferently.

"How is that possible?"

Zhou Wan suddenly attracted the attention of the office people with a little anxious voice, and when she saw that everyone saw it, Zhou Wan was even more eager to find a crack in the ground to get into, but fortunately, everyone just glanced at it, and went to work on her own, so Zhou Wan felt better.

"How is it impossible, love dramas are basically played like this, the male protagonist and the female protagonist are tired of each other at the beginning, and in the end, they love each other to death, there are many examples." Gu Tian said with a smile.

"It's different." Zhou Wan hurriedly said.

"What's the difference?"

Zhou Wan didn't answer Gu Tian's words directly, but continued to ask: "Then what if he is rude to you and likes to call you by your nickname?" ”

Looking at Gu Tian's scrutinizing eyes, Zhou Wan whispered: "For example... For example, Xiaowan. ”

Gu Tian held back a smile, wanting to laugh but embarrassed to laugh, she could only hum and say, "That Wan... Then Xiaowan, you have to be careful. ”

Zhou Wan subconsciously asked, "What careful?" ”

Gu Tian: "That...."

She paused for a moment and asked with a smile: "Sister Wan, let me ask you, do you resent him calling you like that?" ”
