Even most long-time business owners do not understand credit card processing and the details of how it all works. Here at Alpha Payment Processing, it is our goal to not only earn your business through honesty and integrity but to also help our merchants understand how credit card processing works. Things to understand are: interchange cost set by the card issuing companies vs. what is actually a markup; how PIN-based debit works and what to expect; what card types are the most expensive; and debunking some of the stigmas surrounding the credit card processing industry.
