Q: What happens during a typical Internet credit card transaction?

Typically, a transaction will take place in two phases, a charge and a settlement. In the first phase a charge is made and money for the transaction is set aside from the cardholder's account. In the second phase, that money is transferred from the cardholder to the merchant. In general, the first transaction takes place as soon as the card is submitted, allowing the merchant to quickly secure the funds for the transaction. The second phase takes place later, and is usually done in batches at the end of the business day. Settlements are done in batches because most processors limit the number of settlements that you can do during a certain period, and because it is easier and more economical to void a transaction before funds are transferred than to credit a cardholder account after the fact. If you have ever checked your bank statement to find that there is a separate total for what you have and what is available, this means that a charge has been placed on your account that has not been settled yet. A more detailed outline of a transaction is below:

  1. A customer provides their credit card information to a merchant. Credit card information can be submitted in a number of ways; e.g., their card is swiped though a terminal, they present their card information over the phone, or they type their card information on a website. Depending on how the customer submits their information to the merchant, they can send additional information to the merchant to verify the cardholder's identity for fraud prevention. (If their card was present, additional data will be read from the card and submitted to the merchant to prove that.)
  2. A merchant submits the credit card information to either a processor for approval or to a payment gateway. If the merchant submits their information to a gateway, then the gateway will in turn submit the cardholder's information to a processor for approval.
  3. The processor runs a check on the card, and will respond with an approval or rejection for the transaction to the merchant or the gateway (who will pass that information back to the merchant). The amount of funds requested will be held on the cardholder's account, but will not be transferred out yet.
  4. The merchant notifies the customer of the success or failure of the transaction. If the transaction is successful, then the merchant will ship products/provide services to the customer.
  5. At a later time, usually at the end of the day or week, the merchant (or if the merchant is using a gateway, then the merchant's gateway) will settle the transactions it has performed that day.  By communicating again with the processor, the funds that were charged earlier are then transferred for the cardholder's accounts to the merchant's account.

Q: What are some of the means that a customer can provide their credit card information, and what is the difference?

Most credit card transactions can be broken down into two types: e-commerce transactions and card-present transactions. The fees associated with credit card transactions are dependant on the type of transaction, so it is important to note the differences between the two.

An e-commerce transaction or a mail-order-telephone-order (MOTO) transaction is a transaction where the credit card is not present. These transactions are usually either online transactions or phone transactions where the credit card number, expiration date, and billing information are taken from the customer. Because transactions where the credit card is not physically present are more prone to fraud or theft, the fees associated with these types of transactions are typically higher than then when the credit card is present for verification. The higher fees allow for the costs associated with charge-back fraud.

A card-present transaction is one where the credit card being charged is physically present and swiped through a terminal. These are referred to as POS (point of sale) transactions. The credit card number, expiration date, and any additional data are read from the magnetic stripe on the back of the credit card. Because of the added security provided by a card-present transaction, the fees associated with each transaction are typically lower.

Q: What is a payment gateway?

A gateway is a value-added service provider that will, in exchange for a fee (usually a percentage of your sales and a number of associated fees), accept and process credit card transactions from you. Payment gateways generally provide additional services beyond payment processing such as transaction logging, automatic settlement, and reporting as well as additional security and fraud prevention.

Q: What is a payment processor?

A payment processor is a service company that performs charges and settlements for credit card transactions. Every credit card transaction eventually goes through a payment processor.

Q: What are the differences between the credit card processing suites (E-Payment Integrator and Direct Payment Integrator)

E-Payment Integrator is used to submit credit card or eCheck (ACH) transactions to Internet payment gateways; Direct Payment Integrator submits credit card transactions directly to payment processors.

Q: What is a merchant account?

A merchant account is simply a bank account that is set up for a merchant. The big difference between a merchant account and a regular bank account is that a merchant account provides support for one or more processors to deposit funds made by credit card transactions processed through them.  Contact the /n software support team for help setting up a merchant account enabled for a supported processor or gateway.

Q: What do I have to do to go through a payment gateway?

You will need to create an account with the payment gateway, which you will use to authenticate all transactions that you send to the gateway. The components of E-Payment Integrator support multiple payment gateways, thus allowing you to reuse the same code across any of the supported gateways provided in the toolkit. The Gateway Setup and Required Properties section of the Help documentation shows the required authentication, supported transactions, and testing information for each gateway. As you finalize the production system, you will also need to set up a merchant account with your bank if you do not already have one.

Q: What do I have to do to go through a payment processor?

You simply need to make sure that you have a merchant account that is compatible with that processor. You can check with the bank that issues your merchant account about what processors are supported, but generally you are going to find that most merchant accounts support the TSYS processor.
