Now the company has simplified things, dropping the $.15 per-transaction fee for swiped purchases, charging a simple 2.75 percent on each transaction. If, however, that transaction is being made without swiping the actual card the $.15 transaction fee sadly comes back, but the percentage fee has gone down from 4.0 percent to 3.5. So, a little less of your handiwork will be absorbed by the man.
