I heard about Square about a year ago, and was trying to utilize it for my business when we do transactions with customers. For testing purposes it wasn’t allowed until this year to be used by businesses, and since then has exploded from 1 mil in transactions 3 months ago, to 3 million in transactions a day last friday. Looks like a promising new tech startup is proving useful to consumers. With each transaction that you accept on your square reader connected to your mobile device, you can expect to pay around 3% for the transaction fee. That is less than the monthly fee of 70 dollars plus 3% we were paying for our archaic credit card reader that we used in the past.
