After passing through the turnstile, He Ao glanced at the card in his hand.
Printed on the card was the appearance of a thin, middle-aged man who looked very similar to Joey. There were also some dried blood stains on the card that had not been removed.
This is Joey's father's job card.
The opening principle of this kind of factory-customized work card is that the chip inside all work cards will have a code, and this code corresponds to the worker's job number.
When the work card is produced for the first time, there will be a special authorization machine to authorize the work card. Only the authorized work card can swipe the door lock machine. The maximum validity period of this authorization is one month.
The gate itself is both an authorization machine and a verification machine.
Whenever the authorization expires, the gate will read the code of the work badge and upload the data to the cloud database, and compare it with the worker information in the database.
After confirming that the worker is still employed, the gate will re-authorize the work badge for a short period of time.
Generally, the reauthorization time is set at a fixed time of a certain month, usually within the three days from the 5th to the 7th. The factory's scheduling system will allow everyone to schedule a shift within the three days from the 5th to the 7th.
, so that the gate can re-authorize the work card.
Therefore, there is a loophole in this access control system. After a factory worker leaves his job, his work badge is still valid for a short period of time, which means that he can swipe the access control until the authorization of his work badge expires.
Therefore, generally, the factory will require workers who leave their jobs to return their work badges. The returned work badges can be used by new employees after resetting the code and reprinting the image.
However, no one will ask the deceased in a factory accident to return his work badge.
When Joey came to the factory to receive his parents' bodies, the staff returned the broken bodies to Joey without any inspection.
Joey found his father's work badge in the work clothes affixed to his father's body. In fact, he also found his mother's work badge, except that the work badge had been broken into pieces.
After finding the job tags, Joey recalled the knowledge about these job tags, which he had read in an encyclopedia magazine in the library.
He immediately returned to the library, found the encyclopedia magazine again, and confirmed that the access control system of Avis Machinery Factory was the kind of access control system described in the encyclopedia magazine.
After understanding the loopholes in the system, he already had a plan in mind.
Although Joey's parents had an accident before the 5th, usually such deaths occur relatively rarely and the handling staff are not very experienced.
So Joey guessed that it might take several days after his parents died before the factory administrators thought of deleting their parents' personal information from the database.
So when he came to the factory to protest on the 5th of last month, he secretly used his father's work badge to swipe the turnstile. As he expected, his father's information was not deleted from the database, so he obtained a new short-term authorization.
.
His actions were very secretive. Most people, including many senior managers in the factory, did not know the operating principles of the gates or the operating loopholes of the gates, so no one took precautions against him.
Today is the 3rd, and the temporary authorization obtained last time will not expire until the 7th.
Of course, in addition to the gates that are authorized once a month and have loopholes, are there any gates on the market that can calculate and verify employee information in real time?
Yes, but you have to pay extra.
Not only do you need to pay extra for the equipment, but you also need to pay extra for the continued purchase of data traffic.
Chenxi City's technology is very advanced, but the factory is not willing to spend any more money that it can afford.
He Ao sighed softly and walked towards the depths of the factory.
Joey is not stupid, he is even very smart, he is just too weak.
After entering the factory, He Ao followed Joey's memory and walked step by step towards Area I.
Only by actually seeing the robotic arm, understanding the specific situation, and conducting further investigation can He Ao know the real cause of the accident.
Joey had tried several times before to enter Area I or even the factory for internal investigation, but was blocked by various surveillance personnel.
The defense level of Anvis Machinery Factory seems to be very high.
That's why He Ao designed today to lure all the intelligence personnel away so that he could enter the factory to investigate. This plan was arranged before meeting Jack. The man with a similar body shape to him was the one he asked Christos
Helped me find it.
After meeting Jack, He Ao became more determined to sneak into the factory to investigate.
Of course, there were two reasons why he went to pick up Jack's blank card.
The first is to plant a psychological hint for the intelligence officers who are observing him.
Lead these intelligence officers to think that he will use Jack's card to bypass the access control, so that they will be in a less nervous state before the actual alarm is issued, thinking that He Ao has not entered the factory, and cast a layer on He Ao's investigation.
Camouflage color.
And the second one is to send a message to Jack.
The position he was standing at that time was with his back to the eyeliner who was following him at close range, and the other party could not see his facial expression.
——
Bang bang bang——
"Open the door."
A huge knock on the door came from outside the house, and the old door creaked with the force of this bull-like force.
"Open the door quickly, the Charity Association will send flour."
The knocking on the door continued for a while, and the voice of the person outside the door became more and more irritable.
Finally, the knocking on the door stopped abruptly, and the entire space fell into a brief silence.
However, the silence was soon broken by a loud noise.
This old door was knocked open by someone outside.
Almost instantly, several burly men with guns rushed in. They crowded into the small porch and began to move forward quickly.
They searched around and checked the bathroom, kitchen, living room, and bedroom in turn.
"Shit, run away."
One of the strong men looked at the messy bedroom and cursed.
"Look again."
The strong man at the front waved his hand and continued to check in the living room.
His eyes finally stopped in front of a home surveillance camera, which glowed slightly with blue light and seemed to be running.
Then he shot the camera.
······
The surveillance screen in the field of vision flickered, indicating that the network was disconnected.
Jack exited the monitoring software, turned off his bracelet, looked up at his daughter sitting next to him, and gently touched her head.
At this moment they are sitting in a wide and bright hall.
"What happened?"
A plump woman in simple clothes ran over from a distance, panting and looking at Jack,
"I was suddenly asked to resign and have to go to another city. Do you know how hard it was for me to find this job? The working environment is good, the money is enough, and except for the naughty chef, it is almost a perfect job.
Already working."
Jack looked at his wife's complaining look, smiled softly, stood up and hugged his wife, "Elsa, we are free."
"ah?"
Elsa was a little confused.
Jack smiled, said nothing, and just hugged his wife tightly.
In the past two years, every time he wanted to buy a ticket to leave the city, he would be threatened by inexplicable gang members. He knew that he was under surveillance. Although the other party was not watching him all the time, he wanted to
Make sure he won't talk nonsense, make sure he won't flee the city, and keep him under surveillance.
After several failed attempts, he had almost given up on escaping.
Until this afternoon when He Ao took the blank card from him, after the words "thank you", He Ao gently mouthed to him.
He understood the meaning of that mouth shape.
'run'
Jack chose to believe this young man. This time, he bought a ticket and left without any hindrance. During that brief blank period, everyone in the Avis Group seemed to be chasing the young man.
"Okay, okay," Aisha patted her husband's back gently, "If you didn't tell me why you left, you should tell me where you are going, right?"
"Passengers heading to Kaya City, please note that the morning airship M1393 aerostat flying from Dawn City to Kaya City will start checking in tickets soon. Passengers taking M1393 are asked to go to the check-in area as soon as possible to start checking in."
A gentle mechanical female voice suddenly came from the PA in the hall.
Jack let go of his wife, then grabbed her hand with one hand, and picked up his daughter who was blinking with the other hand.
