A Japanese company called Strapya launches its Music Card MP3 player that is about the size of a credit card. The Music Card has 2GB internal memory and supports MP3 and WMA audio files. It provides a 2.5mm jack, instead of 3.5mm and comes with a 3.5mm adapter so you can still use your own headphones.
The Music Card’s battery allows up to 15 hours of playback and can be recharged via USB. The card player is available in six versions, Casette Tape, Chocolate, Gold Credit Card, Strawberry Chocolate, Vintage Camera and White Chocolate. It is priced at 2400 Yen.
