What is Credit Card Processing?

Credit Card Processing is one of those processes which simply refers to the sequence of operations needed to complete purchases made in person, electronically, by phone, or by mail using a credit card.

How Does Credit Card Processing Work?

The Credit Card Processing takes place to solidify funds for the transaction between the customer and the merchant. It has 3 stages :

  • Stage 1: Authorization-

    A cardholder starts a credit card transaction by presenting his or her card to a merchant as a payment for goods or services.

    The merchant shall use his credit card machine, software, or gateway to transmit the information of the cardholder and the details of the transaction to his bank or the bank’s processor.

    The acquiring bank (or its processor) captures the transaction information and routes it through the appropriate card network to the cardholder’s issuing bank for approval.

    MasterCard transaction information is routed between issuing and acquiring banks through MasterCard’s Banknet network. Visa transactions are routed through Visa’s VisaNet network.

    The credit card issuer receives the transaction information from the acquiring bank (or its processor) through Banknet or VisaNet and responds by approving or declining the transaction after checking to ensure, among other things, that the transaction information is valid, the cardholder has sufficient balance to make the purchase and that the account is in good standing.

    The card issuer sends a response code back through the appropriate network to the acquiring bank (or its processor).

    The response code reaches the merchant’s terminal, software or gateway and is stored in a batch file awaiting settlement.

  • Stage 2: Settlement-

    A merchant begins the settlement process by sending a batch of approved authorizations to their acquiring bank (or the bank’s processor).Authorization batches are normally sent at the end of each business day.

    The acquiring bank (or its processor) shall reconcile and transmit the batch of authorisations through an interchange through the network of the appropriate card association (VisaNet or Banknet).

    The acquiring bank also deposits funds from sales into the merchant’s bank account via the automated clearing house (ACH) and debits the merchant’s account for processing fees either monthly, daily, or both depending on the merchant’s processing agreement.

    The card association debits the issuing bank’s account and credits the acquiring bank’s account for the net amount of the authorizations which is gross receipts less interchange and network fees.

    The cardholder is responsible for repaying his or her issuing bank for the purchase and any accrued interest and fees associated with the card agreement.

  • Stage 3: Disputes-

    In some cases, the payment card fee is refunded days or months after the process described above. It may be that the goods were defective or that the charge for the cards was fraudulent/made without authorization.

    In either case, the cardholder demands that the charge be dropped.

    The merchant can either agree to a refund or enter into a dispute process to prove that the charge was not fraudulent.

    Additional resources between the banks must be devoted to the dispute, so additional costs may be incurred.

The Key Players in Credit Card Processing

Customer (Cardholder): A customer obtains from the issuing bank a credit or debit card and uses the account to pay for goods or services. So, they can also be termed as the cardholder in this process. Merchant: In exchange for goods or services, a merchant is any type of business that accepts card payments. Payment Processors: Companies that handle credit and debit card transactions are payment processors. Payment processors connect merchants, merchant banks, card networks and others to make card payments possible. Credit Card Associations: These are the credit card companies like Visa, Mastercard, and American Express that create credit cards. Often referred to as credit card networks, they set all the rules, determine a fair processing rate for each sector, maintain hardware and software security and encryption, how and when to advertise to consumers, and so on. Credit Card Issuing Banks (Cardholder’s Bank) : These are financial institutions that issue credit cards to customers, such as Chase, Citi, and Wells Fargo. Some card organizations, such as Discover and American Express, also assume the role of an issuing bank, creating their own cards and issuing them. Issuing banks are those that evaluate the creditworthiness of a consumer before deciding whether to issue a card to a consumer. Credit Card Acquirers (Merchant’s Bank) : They are often known as acquiring banks, but in the conventional context they don't all have to be a bank; they may be financial institutions with bank-like features. They set up a merchant, a specialized bank account used exclusively to collect card payments from issuing banks, with a merchant account. Credit Card Processors: They are the one-stop-shop companies that a retailer works with to set up card payment processing. Merchants might directly deal with them or could partner with one of their resellers. Processors set up payment processing for merchants, helping them get a merchant account and ensuring that they have the proper payment card hardware and applications.

What are Credit Card Processing Fees?

These fees can vary depending on the type of credit cards you accept, and they include several different layers of charges:

Interchange fees: This fee, which can also be referred to as a swipe fee or a discount rate, is paid by businesses directly to the credit card issuer. This fee may be higher for online purchases to account for the increased risk of fraud when a credit card isn’t present for a transaction. Also note that interchange fees can depend on the type of card, how much is being charged, and the type of business being operated.

Payment processor fees: It’s also possible the payment processor will charge an additional fee to facilitate the payment. Payment processor fees can be broken down into smaller fees that take place over time and may include monthly or annual account fees, equipment rental fees, withdrawal fees, statement fees and others.

Assessment fees: Assessment fees are paid to the credit card network for the purchase to take place. Note that assessment fees are paid based on total monthly sales instead of a per-transaction basis.

What are Credit Card Pricing Models?

Interchange Pricing:

Interchange fees are paid or collected by the card-issuing banks that provide Visa, MasterCard, Discover, and American Express cards. These cards are commonly consumer credit or debit cards, but can also be corporate, business, purchasing or rewards cards. Interchange fees typically consist of a percentage of each transaction accompanied by a flat per-transaction fee. The exact cost per transaction depends mainly on the type of card and how it’s processed.

Tiered Pricing:

This type of pricing model comes with different pricing for transactions in different tiers or buckets. For example, certain qualified transactions may be charged a lower rate, whereas others require a higher percentage in fees. This type of pricing typically works best for merchants who process most of their transactions in the lowest tier.

Flat Rate Pricing:

Flat rate pricing works exactly as it sounds. With this pricing model, the credit card processor will charge the merchant a fixed percentage of each transaction plus a small per-transaction fee (usually $0.20 to $0.30 per transaction). This pricing model makes it easy for merchants to anticipate their credit card processing costs over time.

Billback Pricing:

Billback pricing or Enhanced Recover Reduced Percent (ERR) is a mix of Interchange Cost Plus and Tiered Pricing. The merchant is charged a flat discount rate like they would be if they were on Interchange, but then at the end of the month, they are charged the ERR rate which is dependent on how the transaction qualifies.

Frequently Asked Questions About Credit Card Processing

What does processing mean on credit cards?

A customer's credit card data is submitted to the processing network, which contacts the issuing bank to ensure that sufficient credit is available on the consumer’s account to cover the cost of the purchase. Many anti-fraud checks are also performed, and the transaction is accepted if no red flags are raised. The payment processor then processes the transaction, paying the interchange to the issuing bank and credit card associations, and keeping the remainder of the processing charge. Only then are funds released to the business owner’s merchant account.

What is the average fee for credit card processing?

Any time a customer makes a transaction using a credit card, businesses are expected to pay fees to receive credit as payment. Depending on the form of credit cards you accept, these payments can vary and include several different layers of charges. The average credit card processing fees range from 1.5 percent to 3.5 percent of each transaction, according to Payment Depot although the final percentage depends on a whole host of factors such as interchange fees etc.

What does payment processing mean?

Payment processing is simply a series of steps necessary for the authentication and approval of a transaction, followed by an additional set of steps that automates the transfer of funds from the transaction to the merchant and the various responsible parties. Using advanced hardware and software, payment processing helps process, validate and approve or reject credit card transactions.
