I don't think news that Square is releasing a safer card reader this summer should put off users of their existing reader, but it's worth keeping an eye out for if you want to ensure all your credit card data is encrypted. This comes after Visa invested in the start-up, so it makes sense also that Square's going to take on some of Visa's best practices that will "help increase trust in innovative payment solutions," according to Square COO Keith Rabois.

It's not known if Square will replace all the card readers being used today (in fact, the readers just went on sale at Apple stores last week for $10 each), but apparently the only new feature in the third model of their card readers will be this new form of encryption. [Visa via Techcrunch]
