Four-party system in card payments

The four-party system is the foundation of modern Visa and Mastercard card transactions, enabling businesses and consumers to transact seamlessly worldwide. Whether you’re an online merchant, an acquirer, a card issuer, or a consumer, this model ensures that every payment flows securely and efficiently.

At QubePay, we specialize in helping merchants navigate this system, ensuring that payments are processed smoothly while minimizing risk and maximizing efficiency. Let’s break down the four-party system and how each role functions in the payment ecosystem.

What is the Four-Party System in Card Payments?

The four-party model consists of:
1️⃣ Cardholder (Consumer) – The person making the payment
2️⃣ Merchant (Business accepting payments) – The business providing goods or services
3️⃣ Issuer (Cardholder’s Bank) – The bank that issued the card to the consumer
4️⃣ Acquirer (Merchant’s Payment Processor) – The bank or PSP that processes the payment on behalf of the merchant

This system ensures that transactions are secure, regulated, and efficiently processed by distributing responsibilities among multiple players.

How the Four-Party System Works

1️⃣ The Cardholder Makes a Purchase

• The customer (cardholder) initiates a purchase at a merchant’s store or website using a Visa, Mastercard, or other branded payment card.
• This can be done via contactless, chip & PIN, mobile wallet, or online checkout.

2️⃣ The Merchant Requests Payment Authorization

• The merchant sends the transaction details to the acquirer (payment processor or acquiring bank) via a POS system, payment gateway, or e-commerce checkout page.
• QubePay acts as the acquirer for merchants, ensuring seamless payment processing.

3️⃣ The Acquirer Forwards the Request to the Issuer

• The acquirer sends the transaction request to the card network (Visa/Mastercard), which then routes it to the issuer bank (cardholder’s bank).
• The issuer checks the cardholder’s account to confirm sufficient funds or available credit.

4️⃣ The Issuer Approves or Declines the Transaction

• If the funds are available, the issuer approves the transaction and sends an authorization back through Visa/Mastercard to the acquirer.
• If the card is declined (due to insufficient funds, fraud concerns, or other issues), the transaction fails.

5️⃣ Funds Settlement & Merchant Payment

• Once authorized, the issuer releases the funds to the acquirer, who then settles the amount to the merchant’s account (minus processing fees).
• QubePay ensures fast and secure settlement, reducing delays and improving cash flow for businesses.

6️⃣ Transaction Completion

• The merchant completes the sale, and the cardholder receives their purchase confirmation.
