More patent bullshit

The high-profile startup Square has filed a lawsuit against a company to clear up the rights to its invention which allows you to pay for products by swiping your credit card into a card reader plugged into your mobile phone.

This is US Government patent ignorance. Via previous art and common industry practice I can plug anything I want into any device I own. I can plug a shoe lace into a refrigerator and no government patent official is going to tell me I violated the law. Plugging one thing into another has been prior art for 1 million years.
