Here is a new thinnest MP3 player produced by the country of Sakura (Japan). The MP3 Player is shaped like your Visa Credit Card with some real look of a credit card.
The manufacturer even add a line of numbers code to “fake” the mp3 player as your credit card.
Credit card sized MP3 player looks really cool with 8 buttons to navigate through your songs collection. You’d also found an OLED display (85 x 54mm) and a 3.5mm jack port at the rear side.
The question is, how large is the internal storage? Can we expand the memory? By looking at the picture above, it seems not expandable. No word on pricing and availability yet.
