If you don't already take American Express, add it now. "Everyone has a bankcard" is wrong. 16% of all American Express cardholders don't have any other bankcards. And while the rate is a bit higher, American Express has the best Membership Rewards programs out there so folks want to use them. And use them they do with an average American Express charge being 27% higher than the average bankcard purchase. 55% of American Express cardholders look for the decal to see if the card is accepted, so post the decal and enjoy making new customers!

5. Add an electronic check scanner and merchant processing iso program services program to take all checks from your customers safely, quickly and without fear of fraud or NSF losses, for less than you're paying for your credit card processing now.

Stopping your credit card processing and merchant services program will no more increase your "profits" than standing in a garage will make you a car because it's simply not going to increase your total sales. It's been proven in America for over 40 years that the number one way to increase a merchant's total sales is to accept all forms of payment from your customers that they prefer to make.
