Reservegelschein yes, no card with magnetic stripe

First you should be aware that a card with magnetic stripe should not be located close to a smartphone or mobile phones, as the magnetic strip can be demagnetized and thus unusable. Thus I would never stick a debit card on a smartphone. The same goes for my train ticket and give all the cards with magnetic strips. The velvety surface and the stretchable fabric protects cards undoubtedly, and fit into the card slots of my purse. My new identity card fits in perfectly, he also slips alone not get out, but I would rather carry in your wallet. The same goes for my health card.

When smart or iPhone I would accommodate more things like business cards, emergency card, or even a 5-10 bill. Just things that you can do on the road, if you do not (letter) will take pocket and only the smartphone. Of course, the headphones fit in, but it forms a bump can not be ignored. Who is running only with the iPhone on a regular basis and a few bags has, that may be an alternative.
The build quality is okay, the red glows, the glue is sufficient - but smells all CHARITIK 3M Adhesive Pouch Wallet Card after the adhesive.
I think it is more of a gimmick; o) and makes me actually only eye-catching, or even for monthly tickets (without magnetic strips), a Reserve Currency, emergency card and a couple of business cards make sense!.
