About Credit Card Processing

Credit card processing occurs in 2 steps — a real-time authorization and a capture (settlement)

of the funds that the cardholder’s issuing bank authorizes. You perform these 2 steps either as

a single transaction or as 2 transactions, depending on your business model.

For an authorization, the server sends the transaction information to a credit card processor.

The processor routes the transaction through the financial networks to the cardholder’s issuing

bank. The issuing bank checks whether the card is valid. It evaluates whether sufficient credit

exists, checks values such as address verification service and card security codes, and returns a

response such as Approved, Declined, or Referral.

You receive the response a few seconds after you submit the transaction to the server. If the

bank approves an authorization, it temporarily reserves the credit for the amount of the

transaction to prepare to capture (fulfill) the transaction. The hold on funds typically lasts for

about a 3-7 days.

Capturing a transaction actually transfers the funds to your bank. At least once a day, PayPal

gathers all transactions flagged for settlement and sends them in a batch file to the processor.

The processor then charges the issuing bank and transfers the funds to your bank. It typically

takes a few days before the money is available in your account, depending on your bank.

NOTE: For card-not-present transactions; such as online transactions, merchants are required

to provide a service or ship goods before or on the same day the transaction is

captured.
