What is the difference between payment and traditional pos machines and hand brushes?

Both of them transmit transaction data to banks, acquiring institutions and host servers of UnionPay by reading cards.

As the transaction data processing center, UnionPay collates the transaction data and funds, issues settlement instructions to the acquirer, and finally completes the credit card collection operation;

Shapes to compare:

The traditional POS machine is large in shape, with a physical keyboard, which can be divided into two types: mobile machine and fixed machine, and hot printing paper, which can print signature receipts. The mobile phone card reader is very compact, the audio version is connected to the earphone hole of the mobile phone, the Bluetooth version is connected to the mobile phone through Bluetooth, and the card is swiped on the card reader through APP operation;

From the comparison of functions:

The main function of traditional POS is to collect money, and the application scenario is used by merchants operated by entities to collect money; The application scenario of mobile phone card reader is personal convenience payment. In addition to the collection function, there are more convenience functions, such as water, electricity, coal, telephone recharge, credit card repayment, transfer and remittance, train tickets, plane tickets and so on.

From the comparison of processing methods and access conditions, both processing methods are to apply to banks and third-party payment companies, and e-commerce platforms can also be purchased. Formal traditional POS machines need to provide merchants with three certificates: business license, legal person ID card and bank license; More than 95% of companies that use mobile phone card readers only need users to provide ID cards and bank cards for real-name verification, which is relatively convenient; From the comparison of safety factors:

From the trading principle, as long as it is a regular machine, both are safe. The traditional POS machine adopts one machine and one household, three certificates for merchants to access the network, physical keyboard and printing receipts, which is more standardized. The credit card reader adopts the method of one machine, one code and real-name authentication, and reduces the risk in the transaction by limiting the single amount, thus achieving the purpose of convenient payment. Whether it is safe or not depends on the flow of funds. After swiping the card, the fund settlement parties are UnionPay, banks and payment institutions. The funds of this machine have only been liquidated once, and the funds are settled by formal institutions, and the flow is clear and safe, and vice versa.
