What is Payment Gateway?

Online transactions are facilitated by mobile payment gateways, which let consumers and sellers pay for goods through applications. These gateways' primary job is to collect, process, encrypt, validate, and send transaction data from customers to merchants. The normal payment procedure entails the user adding an item to their shopping cart, choosing a payment option, and then being forwarded to a gateway website, such as PayPal.

The gateway sends the user's information to the bank, verifying the transaction's validity and ensuring the buyer has the funds to cover it. If the verification is successful, the app receives a payment confirmation, and the retailer gets an order confirmation. The merchant notices the funds in their account when the gateway starts a payment settlement. Due to the ease of mobile payments, people are moving away from using actual currency or banknotes.
