What is it? Square is a smart phone application and card reader combination. The free account allows you to key in credit card numbers on your iPhone, iPad, or Android device. Square also mails you a free card reader that plugs into the headphone jack of your device. It allows anyone – seriously, anyone – to accept credit cards from anywhere.
How do you get started? You simply sign up for an account online or by downloading the application to your iPhone, iPad, or Android phone. Once you make an account, you’ll be required to enter your social security number, U.S. based bank account, date of birth, and mailing address. You can immediately begin accepting credit cards by keying in the card number. The company will ship you a card reader in 2 to 5 days.

Quite often I am asked by my readers, clients or just friends and people I meet how they can start a business without investing any money into it yet still build a profitable company.
