With the help of Square -credit card reader for iPhone- and an iPod they have achieved something that I would not have bet that was possible: a cassette reader, although of course with certain limitations.
Since credit cards work with a magnetic stripe, the ingenuity Evan Long has managed to create a reader of the old tapes we used to listen to. on the walkman certainly not a few years ago.
The truth is that it is quite an important curiosity and something really surprising, so from here our applause to the crack of Evan Long and hope that he will soon delight us with another marvel.
