| Client: | A global merchant payment processing company |
| Industry: | Banking and Payment Solutions |
| Size: | Large enterprise serving diverse merchants |
Project Objective
To design and implement Agile, a cloud-based platform that streamlines the entire transaction process. The platform provides merchants with:
- A single point of contact for all payment processing needs.
- Integrated solutions for credit/debit cards, ACH, mobile payments, and loyalty programs.
- Real-time transaction visibility and robust reporting tools.
Project Overview
The Agile platform implementation was structured into six key stages to ensure a seamless and secure transition:
Stage 1: Authorization
- Developed a secure mechanism to validate merchant details via backend API calls before transaction initiation.
- Enabled cardholder payment authorization by integrating POS terminals with acquiring banks and payment networks.
- Included Address Verification Service (AVS) and card security codes (e.g., CVV) for fraud prevention.

Stage 2: Authentication
- Implemented fraud protection tools for cardholder verification.
- Verified billing details and credit card validity with issuing banks using industry-standard APIs.
- Introduced token-based login for merchants, enhancing security during transaction management.

Stage 3: Clearing and Settlement
- Automated batch processing for end-of-day transactions.
- Ensured seamless communication between acquiring banks and credit card networks for settlement.
- Optimized payment transfer timelines to within 24-48 hours.
Stage 4: Credit Card Transaction Participants
- Detailed collaboration between all transaction participants:
- Cardholder: Initiates the transaction.
- Merchant: Accepts the transaction.
- Acquirer: Processes the transaction on behalf of the merchant.
- Issuing Bank: Provides authorization and debits the cardholder’s account.
- Card Networks Facilitate transaction processing between participants.
Stage 5: Credit Card Processing Fees & Costs
- Explained costs associated with processing:
- Interchange Fees: Paid by the acquirer to the issuing bank.
- Assessment Fees: Paid to the card networks for facilitating transactions.
- Acquirer Fees: Paid by the merchant to their acquiring bank.
Stage 6: When a Credit Card Transaction Gets Declined
- Documented scenarios where transactions fail:
- Insufficient funds in the cardholder’s account.
- Suspicious activity flagged by fraud detection systems.
- Expired or invalid credit card information.
- Provided real-time decline notifications and troubleshooting steps for merchants.
