Why does the supermarket scanner not need to enter the password to sweep the money away?

Nowadays, mobile payment is becoming more and more convenient, and many people only bring a mobile phone when they go out, and they don't bring money at all. Whether it's to **, basically even small stores support WeChat payment or Alipay payment, which can be said to be very convenient. Now China has basically entered the cashless era, and some people can't even touch paper money all year round, and only use electronic payment.

However, while electronic payment greatly facilitates people's lives, it also brings some troubles, such as the problem of online fraud, which is now very rampant due to the convenience of electronic payment. It is worth mentioning that in daily life, we will find that when we buy things in the supermarket, when we use WeChat or Alipay, we only need to show the payment code to the cashier, and we only need to scan it to pay. For this situation, many people are a little puzzled, usually we need to enter the password when we go online, why you can pay directly by showing the payment code, is it safe in the end?

In fact, the main reason for this is that password-free payment is opened, and when password-free payment is activated, you can directly scan the code to pay. In fact, for the function of password-free payment, Alipay or WeChat is generally opened by default, when you open Alipay payment or WeChat payment, in fact, there is one in the user agreement is to open the microcredit password-free payment function, but you may not pay attention to it. However, at present, whether it is Alipay or WeChat, in order to ensure the user's money, the amount of password-free payment is 1000 yuan, that is to say, when you pay the merchant within 1000 yuan, you can complete the payment without the payment password.

In fact, the supermarket's code scanner requires merchants to apply to Alipay or WeChat Pay, and they need to submit various information, and then Alipay or WeChat will verify the applicant's information, screen out qualified merchants, and sign a ** agreement after review. If there is a problem, Alipay and WeChat can deal with the money of the supermarket or merchant accordingly. In fact, the barcode scanner generally has two uses, one is to scan the barcode of the product, and the other is to scan the payment code that we usually use.

Speaking of which, many people may feel that they can deduct directly without entering the password, and if others print out their payment code and then use it to pay, in this case, their losses are not very large?

In fact, this concern is completely unnecessary, why? I know that when merchants scan the code, they generally collect money based on the barcode, however, this barcode will change dozens of times every minute, simply put, when you display the payment code, it will be invalid after a few seconds. Therefore, even if someone else prints your barcode, it is completely useless.

Of course, if you are really not at ease, you can directly turn off the password-free payment, but you will have to manually enter the password when you go to the supermarket to buy things in the future.

We know that the payment model of these two methods is not the same. When we scan the merchant's *** for payment, we must first manually enter the amount that matches the goods we purchased, and then enter the password, or some mobile phones can use fingerprint payment, as long as it is set up in advance, the payment is still very fast and easy to operate.

But sometimes for some older people, they are not very skilled in this process, and it will delay time. Especially when the supermarket is busy, it is very inefficient. However, now the network technology is very developed, Alipay, WeChat, etc. have become essential apps for many people.

Banks will cooperate with them, and they will jointly create a barcode scanner, which is the kind we often see. Nowadays, many large supermarkets, including some small convenience stores under large supermarkets, small supermarkets will also cooperate with banks to purchase a barcode scanning gun, which is also very convenient for the supermarket itself.

So why is it that someone else can sweep away our money without entering the password? In fact, our payment code is a password, and when we open the payment code, there will be this clause on the agreement. Don't think what if someone takes a picture of their payment code?

The payment code will be invalid after scanning once, the validity period is very short, the next time will be updated in real time, each time the payment code is different, there will be no who prints our payment code to pay the merchant money will be stolen. Otherwise, they would have lost everyone's trust long ago.

Here's how things are, cardholders, and listen to the cardmaker tribe slowly.

Two days ago, the card merchant tribe spent a 500 yuan order through Apple Pay, and after operating according to the experience of the card merchant tribe, I should have received official WeChat consumption reminders, UnionPay consumption reminders, etc. But! I waited a few minutes and didn't get any warning.

My first instinct was to inquire about the transaction, and the result was that the transaction was not found.

When the cardholder tribe calmed down, I found out that it was my friend's credit card that I had bound to the same bank as my friend, so I didn't receive a spending reminder. Then I really have a new question, why can I enter my password but can spend my friend's credit card? Quite simply, it's because of the password-free payment feature.

Here the card merchant tribe would like to remind everyone that many people will neglect the setting of passwords, and always think that they have set up a "transaction password", but in fact, they have only set up a "query password". As a result, the wrong password can also be consumed.

The card merchant tribe reminds everyone that we now have more and more abundant and convenient channels for receiving consumption reminders, and it is no longer just a way to rely on text messages. It is a good choice to bind the official WeChat or APP of the bank amount, and it is more secure and safer. Have you ever encountered such an oolong incident?

Usually we need to enter a password when paying online, but why don't supermarkets enter a password and scan the password directly?

The main reason is that you have turned on password-free payments. In addition, the feature is usually enabled by Alipay or WeChat by default. When you open Alipay Pay or WeChat Pay, one of the user agreements is to enable microcredit and payment functions, but you may not notice.

So, why can the supermarket's barcode scanner directly deduct money?

In fact, supermarket scanning code guns are not readily available. They need the merchant to apply to Alipay or WeChat Pay and submit various information. Then Alipay or WeChat verifies the applicant's information and filters out the documents that meet the requirements.

After the review is passed, the merchant signs the ** agreement. After signing the ** agreement, the merchant can directly use the gun scanning code to deduct money.

Is it safe for businesses to use password scanners?

You might think that a friend would say that since you can deduct money without entering the password, wouldn't it be a huge loss if someone printed out his payment password and paid it? Actually, there's no need to worry. When the merchant scans **, it mainly collects money according to the barcode.

However, a barcode is different from moment to moment, and it changes dozens of times in a minute. So even if someone prints the current payment**, it doesn't work.

Why can the supermarket scanner sweep the money away without entering the password? If you don't know, take a look.

The supermarket's code scanner can sweep away the money without entering the password, because it has added a face recognition system or a password-free system, and the payment is directly in place!

Now even if you run a red light on the road, you can be recognized, put on the big screen to remind, and even warn and punish, not to mention, Alipay, or something face recognition, password-free payment function, and then the computer system is deposited, so you don't need a password.

The supermarket scanner can sweep away all the money without entering the password. The reason is on the payment code you presented, which is the *** that has allowed others to deduct the amount of the account. It should be kept and not displayed lightly.

Because they have obtained the customer's consent before scanning the code, the terminal setup is like this, as long as you take the initiative to show the payment code, they can sweep the money away according to the regulations.

Because you show the payment code yourself, the supermarket scanner will automatically scan the money in your balance, and you don't need a password.

First of all, we all know that there are two ways to pay by mobile phone, when you scan the merchant's *** payment, you need to enter the password or fingerprint payment to be able to pay successfully. The second kind of words is what we said today, the merchant uses the code scanner to scan your *** directly, and you don't need to enter the password, you can directly pay successfully. The first of the two is relatively safe, after all, you can also confirm whether the amount is correct when entering the password.

In addition, the reason why we don't need to enter *** when we pay in the supermarket is mainly because when we open the payment code, the agreement says that our payment code is a password. And this payment code can only be scanned once, and it is valid for a very short time, so our payment code is different every time, which means that there will be no theft of the payment code or other purposes.

Because the mobile phone has turned on the password-free payment function, you can swipe the money away without entering the password under certain circumstances.

Many people open the payment code before paying. If he is not paying attention, he will be photographed by others, or directly scanned by others to sweep away the money.

No, because it only calculates the part that needs to be used in it, and not everything can be proposed.

Summary. Dear, good evening, I'm glad to answer for you, the supermarket scan code merchant said to password, it should be that you need to enter the password when you pay to complete the payment.

So how do you not need a password?

**Set up. Can every payment device be scanned directly with a payment code?

Pro, WeChat small-amount password-free payment is the payment code payment function, which currently supports password-free consumption of less than 1,000 yuan per order, and up to 10 password-free times per day; The bound wild card does not support activation for the time being, but the rest do. The steps to set it up are as follows: Step 1:

Yes, dear, you only need to enter the card number of your credit card when binding the bank card, and you can complete the binding of the <>

There are only 10 passwordless payments, and after 10 passwordless payments, do you need a payment password?

Yes, pro, and it's 1000 yuan, but generally you go to buy a few dollars of small things, you scan the code directly to pay, and your payment method in the supermarket is different, so you can rest assured, ten times a day to pay, you can't use up the Oh <>

When the merchant said that he wanted a password when scanning the code, did he want to tell him?

Now when you go to the supermarket to buy something, you basically pay directly by mobile phone, whether it is WeChat payment or Alipay payment, as long as your payment code is displayed, the seller's code scanning gun "ticks" to scan, and the payment is successful immediately, and you don't even need to enter the password.

Have you ever wondered why you don't need to enter a password to scan the code to pay? We usually need to click to pay whether we are shopping in ** or ordering takeout, but we don't need to go to the supermarket, why is this?

Because you have already opened password-free payment, and this function is enabled by default, that is to say, as long as you don't turn off this function when you get Alipay, you can go to the supermarket without entering the password.

In the user agreement, there is a function of microcredit password-free payment, but everyone rarely pays attention to it. This small amount is generally set to 1,000 yuan, that is, as long as it is 1,000 yuan or less, the merchant can directly scan the code to receive the payment, and the customer does not need to enter the password.

Of course, scanning code payment is also very concerned about everyone's safety, the supermarket's code scanner is not casually can be applied, taking Alipay as an example, the code scanner needs the merchant to apply to Alipay, and needs to provide a lot of information, and then Alipay will verify the merchant information, and after determining the qualification, it will be issued to the merchant scanner for scanning code collection.

It is worth noting that if the merchant calculates the amount incorrectly, for example, the merchant deducts more money from the user, it is possible to apply for a refund from Alipay. Of course, if you are not at ease, you can manually go to the settings to turn off the password-free payment function, so that although it is troublesome to enter the password every time you pay, it is relatively much safer.
