this is an finished version of a prototype i made. i designed it for use in public transportation. the holder is designed to fit on the underarm but also can be used on the upper arm. it is made to fit one RF-ID chip card.

so far i know RF-ID cards are used in England (oystercard), Germany (Bahn-card), french (got no clue how they call it) and in the netherlands (OV-chip card) as public transportation subscription cards.

the product will cost € 15 ex shipping as it is. the only diffrance between this prototype and the finished model (that will finished with in the next days) will be made from a bit thinner and more flexible leather.
