Everyone seems to be getting on board with Square's iPhone credit card reader -- Apple started selling the device in its stores last week, and even Visa has taken a financial interest in the company. However, due to the popularity of fraud-fighting chip-enabled smart cards on the other side of the pond, Square's offering doesn't quite fit the bill. iZettle has a similar solution for Europe that includes the ever-so-necessary smart card reader, which the company is launching in Sweden this June. Not only does it enable you to accept credit card payments from friends or customers, the app adds a social twist. Merchants can email a photograph and receipt to buyers, who can then share their latest spoils on Facebook. Of course, if this starts to catch on, it could make explaining that "awesome deal" you scored on a new laptop that much more difficult when it pops up on your significant other's news feed.
