Key-card / key

We all take keys with us when we go out, but it is not very convenient for us to put keys in neither our bags nor our pockets. The Key-card is a card with the same dimensions of an ID card, thus allowing it to fit conveniently in your wallet. All your important keys can be put on the Key-card (the thickness is 2mm). As the Key-card doesn’t take up much space it’s convenient to carry with you, whether you choose to carry it in your pocket or bag. When we need our keys to open the door, just push the key out from the Key-card, and when finished simply slide it back in.
