In today's economy, millions of financial transactions take place electronically. Transactions initiated through websites on computers worldwide.

These actions are possible thanks to the use of a payment gateway. In this way, millions of dollars move from buyer to seller and from bank account to bank account.

The use of a gateway enables transactions to achieve a number of objectives needed in modern monetary transactions.

With the advent of online sales and other transactions, the need for efficient and secure transfer of funds and payment gateways for ecommerce information has risen to a higher level. The gateway effectively facilitates these transfers.

The primary goal is to transmit information. This transfer begins when the customer places an order on the website or over the phone. The information entered on the website is encrypted to keep the information secure when transmitted to the merchant's web server.

The data is sent by the merchant to his gateway, where a second encryption takes place. The gateway sends this information to the processor of any receiving bank with which the merchant has an account.

The processor sends the information to the card association. The card association transfers the transaction request to the bank that issued the card. At this point he accepted or rejected it. This response is sent back to the processor.

The process is then reversed from the processor through the gateway back to the web page. The difference this time is that it contains an acceptance or rejection code. The code is then interpreted to merchants or cardholders. The whole process takes a few seconds.
