This is the safest way to store cards and documents when you don't have your wallet with you. The option to mount it in several ways and the strong grip thanks to the Velcro make it hold well to the chosen surface. In my opinion, a better solution would be to use hook tape instead of soft tape, because on most clothes and technical items you encounter the soft version. As a result, for example, it is not easy to attach it to straps or the inside of a backpack with the Molle system.
