Points of Sale (POS)
They are small machines, within the electronic payment system, that enable the flow of trade between a buyer and seller, without cash (cash as it has become known), where the financial intermediary is the ATM card (Bank Card), being linked to the bank accounts of the buyer and seller, and the deduction is made from the first in favor of the second in his account as soon as the transaction is made. The machines operate throughout the shift of the establishments (government agencies and ministries, stores, restaurants, fuel stations, etc.), and with high limits of financial transactions, which makes them the most appropriate and safer option than the cash option.
