Nothing techie about it.  It's basically a rubber band that holds your cash and credit card in a tight package.  It's not expensive since 2 come in a package and does exactly what it's supposed to do.  It keeps your bills organized and the most used CC handy.  For the price you can't beat it.  If you're the fancy type, please buy something 2-5x the price.  For those of us who part of the working class drones, this is a solid product.
