Definition of Payment Processors
A financial organization or a third-party service provider that acts as go-betweens and safely moves money between the customer’s bank and the merchant’s bank is known as a payment processor. They accept digital payments from clients by using payment methods like UPI, debit cards, credit cards, and digital wallets. This ensures that the transaction is done securely without jeopardizing the safety of the user’s funds.
The main objective of the payment processor is to ensure that the money is transferred from the buyer to the seller at the time of purchase with the utmost speed and accuracy. They not only act as middleman but are also outfitted with cutting-edge security features including chargeback and fraud detection. Payment processors will transfer the money only when it is approved to improve transaction security. Payment processors in India must comply with the Payment Card Industry Data Security Standard (PCI DSS) and American Institute of Certified Public Accountants (AICPA) System and Organization Controls (SOC) regulations.
Payment Processors: How Do They Work?

- The transaction is initiated when a customer pays through payment mediums like UPI, credit card, digital wallet, and debit card. Offline and online payments can be made using payment gateways, point-of-sale (POS) machines, e-commerce portals, and mobile applications.
- Once the customer has opted for a mode of payment, the merchant will encrypt the details of the transaction. This process will ensure the security and confidentiality of any pertinent information such as CVV, AVS verification, and others during transmission.
- Then, the encrypted information is sent to the customer’s bank or the issuing bank. After the bank receives the data from the payment processor, the bank will then verify whether the customer has sufficient funds for the transaction.
- After the bank confirms that there is enough balance in the bank account of the customer, it sends back an approved signal.
- To end the process, the payment processor will receive the authorization code from the acquiring bank. This code is then passed to the merchant and the order is completed. Now, the customer will receive a confirmation of the order.
Key Functions of Payment Processors
- Make Transactions Easier: During a transaction, the main responsibility of the payment processor is to receive the transaction details, encrypt them, and securely send them to the acquiring and issuing bank.
- Verifications and Authorisation: To ensure that the customer has sufficient funds available, the payment processor requests an authorization code from the issuing bank. It not only prevents fraud and unauthorized transactions but also verifies the validity of the payment method and the identification of the customer.
- Encryption and Security: Another key role of payment processors is to ensure compliance with security standards like PCI-DSS (Payment Card Industry Data Security Standard) to protect client information. To do this, direct payment processors use tokenization and encryption to securely exchange transaction information among the buyer, seller, and the banks or card network.
- Integration and Convenience: With payment processors, customers can make a purchase simply by using their smartphones. Payment processors in India provide a user-friendly interface and can integrate easily with your current POS system or shopping cart.
- Analytics and Reporting: To help businesses track sales, spot patterns, and improve business management, payment processors facilitate the retrieval of comprehensive reports. These reports provide insightful information on transaction data and improve your marketing and pricing strategies.
- Support for Multi Currencies and Payment Methods: Payment processors in India can receive payment in almost all types of currencies. Businesses can receive payment from around the world can get paid in their local currency.
- Detecting Fraud and Handling Chargebacks: Payment processors can offer advice and service to businesses in managing chargebacks and disputes. To reduce the vulnerability to fraud they use sophisticated algorithms and technologies to scan transactions for fraudulent behavior.

Factors to Consider When Selecting a Payment Processor
- Pricing Structures: For businesses willing to choose a payment processor in India and across the globe, it is important to thoroughly understand the fee structure.

Thus, one should select the perfect payment processor that will suit your business growth, objectives, and volume of transactions well.
- Sales Volume Factors: In sales volume considerations, companies have to balance between those direct payment processors charging lower fees but taking longer time to process and higher-fee-charging ones that give immediate processing. Selecting the right payment processor depends on the specific needs and priorities of the business.
- Compatibility with Business Type: Payment processors in India and worldwide have limitations for particular types of businesses. Therefore, it is important to ensure that the payment processor you choose is compatible with your business type.
