These gadgets help improve our life personally as well as in a business setting. Recently, I attended the Autumn Brew Review and it was my first time to the event with my fiancé. We both wanted to get some food at the event but only had credit cards and no cash on hand. We know that at events and festivals, the food vendors preferred that the customers have cash because it is a lot easier than carrying all the machines to make a credit card transaction. However, to our surprised, one of the food vendors accepts credit cards and they would swipe our cards through her smart phone with a card readering solution from Square. The food cart didn't have a lot of counter space and so this was convenient and environmentally friendly as well because she doesn't have to bring a printer to print a receipt for the customer. She can just email the receipt straight from her phone to my fiancé's email.
