As an office equipment, the POS machine has to be connected to the big part of the telephone line from the very beginning, and now it has been used for a long time to upgrade.
As the cost of acquisition is getting lower and lower, many self-employed individuals and even individuals have come into contact with such a new thing that only large enterprises or chain stores would have. After all, the payment device is a money-related thing. Once you choose an unsafe POS machine, you don't receive money. If the money on your account is gone or your personal information is leaked, the consequences will be unimaginable.
When we choose a POS machine, we must pay attention to whether it has the following characteristics. If it is not, it will take a long time.
screen
The screen is the most important output device of the POS machine. It effectively informs the payer of the amount of money he or she pays. It also prompts the number of digits that have been entered when the password is entered, and whether the password is correct and the transaction is completed.
Some users may think that there is no screen on the POS machine. Anyway, after Bluetooth is connected to the mobile phone, all the information will appear on the screen of the mobile phone, and the screen of the mobile phone is clearer and the color is more abundant.
However, the mobile phone has a major drawback, that is, there are too many operating software, and the underlying system is relatively open and there is a risk of infection. In the unlikely event that there is a gap between the number on the screen and the actual payment, the money will fall into the pocket of the lawless.
keyboard
Compared to the screen, the keyboard is one of the most important input devices on the POS. Like the risk that the screen may encounter, the keyboard that is not included in the POS machine is likely to be tricked by the Trojan virus, but it is tricked into taking a sum of money. After copying the bank card, it will record the password information, and then you want to brush your password. The card will brush your card.
Demolition
When a POS machine produced from a regular manufacturer reaches the user through various channels, it is not known how many people have experienced it. The longer the channel, the more things middlemen can do. We are willing to believe that most people are good citizens who are law-abiding, but we cannot guarantee that everyone will not be mourned.
A POS machine with anti-demolition function can ensure that all functions originally set by the manufacturer are delivered to the user intact. Special screws, precision buckles, and internal self-destructing chips are self-cultivation of a POS machine.
Manufacturer
The cottage has always been a problem that Chinese products cannot avoid. Whether it is all kinds of traditional equipment or the world's latest digital consumer goods, the Chinese people of wisdom and excellence can always produce imitations with high similarity in a short time.
Product model, product name, manufacturer, manufacturer address, implementation standard, production license number, and the People's Bank of China payment license, this information is an important indicator to identify whether a POS machine is a regular product. If the information is ambiguous on the machine itself or on the outer packaging, please take a look at it.
