Explaining What Auth Flow Do Credit Cards Use and the Payment Process

Credit cards use a process called authorization flow, also known as auth flow, to verify transactions and ensure payment is legitimate.

Auth flow involves multiple steps, including card verification, transaction validation, and merchant verification, as explained in the article.

During the auth flow process, the credit card company checks the card's validity and verifies the cardholder's identity to prevent fraudulent transactions.

This process usually takes a few seconds and is transparent to the consumer, who simply enters their card details and confirms the transaction.

The auth flow process is designed to be secure and efficient, allowing merchants to process payments quickly and reliably.

The Auth Flow is a crucial step in the credit card verification process. It's a series of steps that ensure the cardholder's identity and card details are legitimate.

Credit cards use the 3D Secure protocol, which involves a two-factor authentication process. This protocol was introduced to reduce online payment fraud.

During the Auth Flow, the cardholder's card details are passed to the issuing bank for verification. The issuing bank checks the card details against the cardholder's account information.

The Auth Flow also involves a challenge to the cardholder, typically in the form of a one-time password (OTP) or a password. This challenge is used to verify the cardholder's identity.

In some cases, the Auth Flow may involve a redirect to the cardholder's bank's website for further verification. This is often the case for international transactions or high-value transactions.

The Auth Flow is designed to be secure and efficient, allowing for fast and secure online payments. It's a critical component of the credit card verification process.

Credit card authorization is a crucial step in the payment process, and it's essential to understand how it works. The process involves four parties: the customer, the business, the issuer (issuing bank), and the acquirer (acquiring bank).

The customer presents their card for payment, and the business's point-of-sale software sends an authorization request to the acquirer. The acquirer then sends the request to the issuer via the relevant card network.

The issuer reviews the cardholder's account to check for two things: whether the card is valid and whether the cardholder has sufficient funds for the payment. The issuer returns one of two decisions to the acquiring bank: approval or decline.

Here's a breakdown of the parties involved in the credit card authorization process:

The authorization process usually lasts just a few seconds, and it's the short amount of time between tapping your card on the card reader and seeing a "payment approved" message on the screen.

The customer's card has a unique code, such as the CVV or CID, which helps verify their identity. The CVV is a three-digit number found on the back of the card, while the CID is a four-digit number on the front. These codes are also embedded in the EMV chip on the front of most cards today.

If the transaction is approved, the acquirer receives an authorization code, and the transaction is completed. If the transaction is declined, the acquirer receives an error code indicating why it was rejected. In some cases, the issuer may look into the account further to understand what's going on.

Capturing and holding are two crucial steps in the credit card payment process.

Authorization and capture are two separate steps that occur in the payment process.

Authorization is a temporary hold on funds, while capture is when the transaction goes from pending to completed.

Authorization holds can last anywhere from a few minutes to 31 days.

Funds are not transferred during authorization, but during capture.

Most card authorizations expire in 5-10 days, so businesses capture funds before that time.

This delay creates a beneficial buffer that helps merchants.

Capturing funds ensures that merchants receive payment for specific transactions.

It also helps merchants avoid costly chargebacks.

Authorization holds are a helpful mechanism for preventing card fraud and chargebacks.

They ensure that cardholders' accounts immediately reflect their true available balance.

Some acquirers capture funds right after authorization, while others might take a few days.

Generally, card authorizations expire after 5 to 10 days, so capturing and settling payments can't be delayed for too long.

The payment process for credit cards involves a series of steps to ensure a transaction is legitimate and authorized.

The first step is the merchant's request to the payment processor to verify the cardholder's account information.

This request is then sent to the payment processor who forwards it to the credit card network, such as Visa or Mastercard, for further verification.

The credit card network then checks the cardholder's account information against their database to verify the account exists and has sufficient funds.

If the account is valid and has sufficient funds, the credit card network sends an authorization code back to the payment processor.

The payment processor then sends the authorization code back to the merchant, indicating that the transaction is approved.

The purchase definition is a crucial part of the payment process. It involves a card-issuing bank approving or declining a transaction initiated by the cardholder.

Card purchase authorization is a security process that ensures the card is valid and has enough money or credit available for the transaction. This process also verifies that the card has not been reported as lost or stolen.

The rise of credit card usage in the mid-20th century led to a need for an efficient and secure authorization mechanism. Initially, verifications were done manually through a phone call.

As technology advanced, electronic point-of-sale systems and online gateways emerged, allowing for the automation and streamlining of the authorization process.

The payment process starts when the customer presents their credit card information for payment. This can happen when a customer taps or dips their credit card into a payment terminal at a retail location, enters their card information into a secure shopping cart checkout page in an e-commerce setting, or when you enter the credit card details into a virtual terminal after receiving them over the phone.

The acquiring bank takes over communications with other financial institutions, such as the customer's issuing bank, after receiving the customer's payment information.

Here's a breakdown of the steps involved in the authorization process:

The issuing bank sends an approval notice and a unique authorization code if the card number is valid and sufficient funds are available, or a decline message and a decline or error code if the payment authorization fails.

The payment process for credit card transactions involves several steps, and understanding these steps is crucial for smooth transactions.

The customer's payment information is sent to the acquiring bank after receiving the payment details.

The acquiring bank may perform automatic fraud checks, such as comparing the card against certain lists, as part of the authorization process.

The acquiring bank sends the payment information to the card networks, which then forward the transaction to the issuing bank for final authorization.

For example, a Visa-branded card is sent via the Visa payment network, which is a specific card network used for Visa-branded cards.

The acquiring bank or payment processor is the financial institution with which you have your merchant account. This can be a company like ECS Payments.

Your acquiring bank provides credit card processing services to merchants, acting as an intermediary between merchants and the rest of the payment network.

Once a customer starts the payment process with a credit card, the acquiring bank takes over communications with other financial institutions, such as the customer’s issuing bank.

The acquiring bank helps transfer funds between different issuing banks and your merchant account.

Your acquiring bank may perform some automatic fraud checks, such as comparing the card against certain lists, when the customer's payment information is sent to them.

The acquiring bank sends the payment information to the card networks, which can be something like the Visa payment network for a Visa-branded card.

Credit card authorization is a two-way process that protects both the merchant and the cardholder.

A credit card authorization can fail due to fraud or security issues, insufficient funds or credit available, or technical failures.

The authorization process ensures the merchant can deliver goods or services with confidence that funds are available.

The merchant initiates the authorization process by sending the customer's payment details to the payment processor/acquiring bank.

The payment processor then sends the customer's payment information to the card networks, which forward the transaction to the issuer for final authorization.

The issuer transmits a confirmation that the card is valid and has a sufficient credit limit or funds to cover the pending purchase.

A credit card authorization prevents the cardholder from going over their limit and incurring additional fees if they are making purchases with several merchants in the same time frame.
