Innovation might bring us a speaker as thin as your credit card that you can insert in your wallet and carry it anywhere. “Card Speaker” concept was born out of the idea to keep a device really slim that you don’t need a bag or anything bigger than your wallet to carry it. Slide the speaker in one of your wallet’s credit card slot, simply take it out to use it and press the “activate” button. the design is possible due to FFL (Flexible Loundspeaker) and TFB (Thin Film Battery) technology.
