Understand key players in in the value chain of payment
A standard card online transaction, involves four main parties:
1️⃣ The Card Holder – The individual making the payment
2️⃣ The Retailer (Merchant) – The business offering a product or service
3️⃣ The Acquirer (Merchant’s Bank) – Processes payments and routes through card networks
4️⃣ The Issuing Bank (Customer’s Bank) – Issues the card and validates the transaction
How a payment transaction works?
A typical online payment follows this flow:
1️⃣ Customer enters payment information
2️⃣ The request is sent to a PSP or alternative method (wallet, BNPL, etc.)
3️⃣ PSP (if applicable) sends the transaction to the acquirer
4️⃣ Acquirer contacts the issuing bank
5️⃣ The bank checks and approves (or declines) the transaction
6️⃣ If approved, funds are transferred and the merchant is notified
