SECVEL - Credit card holder

Hello,
When I ordered this case (from 3) I was skeptical.
But I went to see the director of my bank branch and have tested the product before witnesses.
And there is top among top.
Without packaging the card data can be stolen easily.
But with this case, impossible to steal data, both with a smartphone, an iPhone or a tablet.
Just my advice, from the slot format of this case with any loyalty card. Then no danger
it falls only to put it back but no hysterics.
Council for hurry.
So I recommended 6 others I handed in my family.
Do not hesitate to acquire this type protects card either for credit card or other cards with data.
I'm talking about all these cards offered by banks Accord, Carrefour etc ... from the moment they are backed your account !!! please
Cordially
Odile
