I do know I have heard about people using credit cards and buy gas/groceries etc and paying off after it posts to improve it quickly.

Any suggestions on a "Cash back credit card?"

If it's FortuneBuilders, be sure to leave your credit cards and checkbook at home. 

Our service for example doesn't charge anything for ACH, but we do charge a % for credit cards. 

(However, I guess it would look pretty cool to have a briefcase handcuffed to your wrist like they do in the movies.)At the last auction I went to, the ONLY way you could pay was by cashier's check and you had to show that you had them in your possession before the auction started to even get a bidder's card. 

Auto pay with a credit card to get the points.

Another question I have is it too ambitious of me to put a card operated system for each laundry machine?

We brought back the wallet and left our business card (real estate agents)  well.... 2-3 years later, guess who calls me up to help them with their house? 

BofA (we bank there already) has a debit only card that you can get with their business account.

I did this in Washington state and it took me about 15 minutes of answering questions and entering my credit card to get my LLC.
