Besides that there are complete systems for processing credit card applications, there are systems for credit card bill processing/generation, there are people at call centres who help in addressing the queries from credit card holders and, very importantly, there are people (sales representatives) who help you in filling the credit card application forms. Another important entity with regards to ‘credit card processing’ process is the credit rating bureaus. Credit card bureaus maintain a database of credit ratings for individuals and businesses. This rating is based on the data received from various credit providers over a period of time. This rating is the most important part of credit card application processing and a bad rating can lead to rejection of the credit card application altogether.

Thus, credit card processing involves a coordinated effort from a lot of professionals and service providers. In that sense, we can also say that credit card processing is an industry in itself that has generated a lot of employment.
