What is debit card processing?
Debit card works same as credit cards. This allows customers to deduct money from their bank account. Debit cards require PIN number to be entered before a purchase can be complete. Most of the people refer Visa/Master card, check cards as debit cards. The process is same but the difference is these cards do not provide a PIN number to make purchases. Check cards have logos familiar as Visa or Master card.

How it works (Process)?
The process work same as credit card i.e. accepting the card except when you enter in the debit card information, the amount to be deducted from the customer’s account. We must assure that when we accept debit card verification service is included. The verification service will include a negative database of bad check writers. This will reduce the fraudulent activities.
