RFID Card Armband Holder

thingiverse

This is an armband holder for standard-sized (i.e. roughly credit card sized) RFID cards. The STL file is for one half of the holder; print two copies to make the complete holder. When the two halves are placed together, there is a pocket to place the card in, and the halves will "lock" together with the pins in the corners -- there are matching holes on the opposite corner. Loop some wide elastic band (sew or hot-glue the ends together) or velcro through the slits on each side to make the armband. I designed this to make my commute to work on my motorcycle easier. I need to swipe an RFID card to get into the garage, and trying to fish the card out of a pocket, with gloves on, is slow and annoying. WIth this holder, I can just wave my arm in front of the card reader and be on my way!
