We gave you a little idea on Square a while back, but in case you forgot, it’s a device that can plug into the headphone jack of your iPod touch or iPhone, and you’ll be able to swipe your credit (or debit) card to purchase goods from businesses. Instead of the boring old pen, you can use your finger to sign the touchscreen. A receipt can then be sent to your email account, though there are plans to implement an option that will send it to your phone via SMS. One of the more useful features of Square is its ability to connect a photo with your account, which should help limit credit card fraud. So will Apple’s iPhone/iPod touch be replacing credit card machines in the near future?
