I didn't drive through the pos machine. Why did Lacarra receive this message?

It may be that the phone number has been registered with the pos machine, so just set the rejection blacklist.

The brand of POS machines in Lacarra is very big, and the market volume of intelligent POS terminals ranks first in the market. However, Lacarra basically covers all the criticisms of the above-mentioned pos machine manufacturers, such as false propaganda, non-refundable deposits, non-payment of credit cards, and automatic increase of POS machine rates.

Some merchants said that they brushed the signboard of Lacarra eight times in a week, and all the seven jumps came from 0.38% warehouse supermarkets. So in this case, they can refuse to pull the blacklist or contact the public security department to recover personal information.

The basic principle of POS system is to create commodity data in a computer file, directly read the barcode on the commodity through the online structure of the computer cash register and the optical reading device on the cash register equipment (or directly input the code through the keyboard), and then display the commodity information (unit price, department, discount ...) immediately, so as to speed up the cash register and make corrections. The detailed information of each commodity sale (price, department, time period and customer level) is automatically recorded and then sent back to the computer by the online framework. Through computer calculation and processing, various sales statistics and analysis information can be generated as the basis for management.

The POS machine reads the magnetic stripe information on the cardholder's bank card through the card reader, the POS machine operator inputs the transaction amount, and the cardholder inputs the personal identification information (i.e. password). The POS machine sends the information to the issuing bank system through the UnionPay center to complete the online transaction, give the information of success or failure, and print the corresponding bill. The application of POS realizes the online consumption of credit cards, debit cards and other bank cards, ensures the safety, rapidity and accuracy of transactions, avoids complicated labor such as manual blacklist inquiry and bill pressing, and improves work efficiency.
