DIY Square reader keychain stash
Square, Inc. makes a magstripe reader that attaches to your smartphone’s minijack and allows you to process credit card transactions with their handy service. It’s a pretty cool setup if you’re interested in payment processing. When you’re not using it though, you’re stuck with this eraser-sized plastic fob that you really don’t know what to do with. It’s small enough to put in your pocket, but it’s a little too important to accidentally let go through the wash, yet you want to keep it handy for when you’ll need it.
MAKE subscriber Steve Cooley may be onto a suitable solution to this problem. Using a dab of Shapelock, a key ring, and a rubber band, he’s fashioned a custom key fob stash that fits the Square reader like a glove. It’s a little kludgy, but it’s a great proof of concept.
