Is the POS machine afraid of lightning? Teach you six tricks "defense"

Credit card withdrawals come in many forms, and POS machines are one of them. I believe that those who use cards are familiar with the process of swiping cards. I will tell you about it here today. I will use the pos machine (hereafter referred to as the machine) to raise the amount. You should pay attention to these basic matters so as not to be left by the slag of the machine pit.

1. Compare the ticket and keep it

The printed machine ticket must be kept. When placing the order, first check whether there is a cardholder's signature on your ticket and whether it is consistent with the signature on the credit card.

2. It is strictly forbidden to dismantle the machine for transformation.

Maybe you are uncomfortable with the existing state of the machine, and want to add a small part to it, for example, those illegally modified records, which is convenient for you to steal other people's bank card information and profit. Warn you again, don't do this, don't die if you don't do it!

3. Check your shopping list

Those who want to buy cards in the mall, I want to remind you, when you spend your card, you must check whether the amount on the shopping receipt is the same as the amount you spend, whether it is your credit card number, if Sign the signature again.

4. Problems with the transaction should tear up the transaction documents

If you have a trading error or cancel a transaction while using a machine transaction, please tear up the wrong transaction slip in time and have the salesperson issue an offset bill on the spot to offset your original transaction for future verification.

5. Check the consumption details

If you fail to trade during the credit card transaction, you must carefully check your credit card spending details when you swipe your card and find out the problem in time to avoid losing your property.

6. Prevent fake card consumption

There are always people who copy and use other people's cards to trade. Therefore, you must take your own cards to prevent them from being used, loss of property, and damage to yours. If you perform TX, you will not be far from the card.

Ok, the precautions about the machine's withdrawal are mentioned here today.

Punched Parts

Of the world's steel, 60 to 70% are sheets, most of which are stamped into finished products. The car body, chassis, fuel tank, radiator fins, boiler drums, container shells, motors, laminations, etc, are all stamped and processed. There are also a large number of Stamping Parts in products such as instruments, household appliances, bicycles, office machinery, and living utensils.

Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness, and strength. Stamping can produce workpieces with reinforcing ribs, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the precision of the workpiece can reach the micron level, and the repeatability is high.

Stamping is an efficient production method. Using compound dies, especially the progressive die, multiple stamping processes can be completed on one press. Generally, hundreds of pieces per minute can be produced by high production efficiency, good working conditions, low production cost.
