"As far as I know, there are two ways to passwords for bank safes, one is fingerprint and the other is password. Which one do you choose?" Director Han asked.
"Fingerprints, I'm also on the safe side. Didn't I say there is absolutely no identical lifting in the world?" Luo Tian said: "So I have always used my own fingerprint as my password."
Procedures for unboxing and retrieving items: Customers can use their fingerprint or password to reserve fingerprint or password when opening an account to rent during business hours. After verification by computer, the safe salesperson will accompany them to unboxing and the customer will store and retrieve items by themselves.
Regulations on storing items in safes: flammable, explosive, and corrosive, poisonous and other dangerous goods, firearms, ammunition, detonators, drugs and other contraband and liquid items shall not be stored in the box. The safe shall not be used for illegal activities such as hiding stolen goods.
If necessary, the bank has the right to ask the renter to unbox the inspection or withdraw the lease at any time.
Safe rent and deposit collection: Rental storage is one year. If it is used for less than one year, rent will be collected on a year basis. Pay it once when opening an account, and a certain amount of deposit will be paid. For continuous rentals, you can be before the expiration of the period.
Pay the next rent in one month and go through the renewal procedures. If you withdraw the safe, you can go to the bank to complete the refund procedures before the due date and return two keys. The bank will refund the deposit.
Regarding the procedures for authorizing others to unbox the safe, in principle, the renter will unbox itself. If the renter cannot use the safe in person due to special reasons, the renter may authorize others to unbox it, and the renter and the authorized person will come to the bank to handle it.
If the authorization procedures are cancelled, the renter shall fill in the cancellation and sign the authorization on the back of the original authorization letter.
Regarding the handling of lost keys: Each safe has only two keys, and the renter is properly kept and is not allowed to copy them by himself. In case of setbacks, the bank should be informed in time and reported the loss and re-examination procedures. If only one is lost,
Users can fill in the lost key and reissue new key requirements, pay the lock replacement fee, and then be accompanied by a full-time bank staff to enter the warehouse, use you to unbox a key, remove the old lock and replace it with a new lock, if two of them are lost
In addition to completing the above procedures, the bank's full-time staff will work with the user to chisel the old lock and replace it with a new lock.
This is the bank's explanation on the safe business. After seeing this, Director Han did not read it anymore. The following content has nothing to do with the case, because Luo Tian used a fingerprint password, which means no matter who committed the crime, he said that no matter who committed the crime, he said that the person who committed the crime was.
, He must get Luo Tian’s fingerprint first, otherwise he will not be able to accomplish anything.
"Luo Tian, think about it carefully. Has anything unusual happened recently? Is there anyone who is suspicious to approach you?" Director Han asked nervously: "Your fingerprint may have been taken away somewhere.
”
"There are more people approaching me recently than ever. Uncle Han, the luminous cup has attracted a lot of people. Antique shops and jewelry shops are almost crowded, and my fingerprints have been left in countless places."
Luo Tian felt a headache when he thought of it: "I really can't remember it now."
"But one thing is very important." Director Han said: "First, this person knows how to fetch fingerprints, and second, this person knows that the luminous cup is in the safe."
"There are only people who know that the luminous cup is in the safe, except for me, there is only the bank. Sure enough, there is still a problem within the bank." Luo Tian said affirmatively: "Even if others know, it is impossible to enter the bank.
”
"Yes, you have to start from the inside. I will remind Captain Qu for this." Director Han looked at Luo Tian with appreciation: "You have strong thinking and logic skills, and if you are a criminal policeman, you will have a lot of prospects."
"How can I get my fingerprint?" Gao Yuanyuan asked in confusion.
"There are sweat glands on the lines of each finger. The sweat secreted by the sweat glands contains water, fat, protein, salt, urea and other ingredients, which have the effect of coagulation and moisturizing; oil and talcum powder can reveal fingerprints that are not easy to see with the naked eye.
Come out. Everyone has different fingerprints, and the fingerprints of the same person's 10 fingers are also different." Director Han explained: "If a person who knows chemistry, he can know that there are at least two ways to extract fingerprints."
"Which two?" This time even Huang Lide couldn't help it. This was a high-tech method of committing the crime.
"The first type is to take a glass tube, put two iodine crystals the size of rice into the tube, put the glass tube on a low heat and heat it slowly. When the iodine is heated and rises to the mouth of the glass tube, the paper-shaped object will be matched with the same color as the surface.
The fingerprint can be clearly visible above the glass tube. This is because there is always a small amount of oil on the fingers, and iodine is very easy to dissolve in the oil. Because the iodine is very dark in color, it can show the fingerprint." Director Han continued
Said: "There is another type, which is what I just mentioned. Because there are sweat glands on the fingers, you can use oil and talcum powder to extract fingerprints. However, this method is more complicated than the one I just mentioned, especially if you are
If you come to commit the crime."
"How do you say this?" Luo Tian asked.
"Because this method requires first grease on your fingers, and then use Shuang's identity, tape and black drawing paper to take out the fingerprints." Director Han said: "If you use this method, you can use it."
, Then the perpetrator must first approach Luo Tian, and then let Luo Tian’s right index finger get oiled."
Oil? Luo Tian was shocked: "Actually, I have been touched with oil in public places recently."
"Where is it?" Director Han was shocked.
"A cafe, I ordered some snacks and had a fork, but I like to eat them with my hands, so I will inevitably get oil on my hands, but I wiped my hands with tissues immediately..." Luo Tian's
My face turned white all of a sudden, tissue, yes, wouldn’t it be that my fingerprints left on the tissue?
"That's right." Director Han slapped his thigh vigorously: "If there were people from the bank present and he was proficient in chemistry, he would have the idea of extracting fingerprints when he saw this scene, which would be logical.
It seems that Captain Qu is going to send a team of people to the cafe for investigation. By the way, does the cafe have a camera?"
"I don't have an impression, because it's open air, so reporter Luo and I were sitting outside." Luo Tian recalled: "There were seats inside, but the air outside was good..."
Alas, what I said now is useless. This matter told Luo Tian that the best tool to use snacks in the future. Luo Tian sighed helplessly: "That's all I can say."
"Okay, I understand everything." Director Han stood up: "I'll go and arrange the work right now. When you calm down, think about it carefully. I'll take the lead if there are suspicious people in the cafe."
"Okay, thank you, Uncle Han."
"I thank you. If every victim is as calm and rational as you, the police will be able to handle it." Director Han walked out strode outside. Luo Tian was impressed from the bottom of his heart. He was worthy of sitting on the front line.
