Hey there macrumors forum members! At my job they use these nifty "phone tags" that are basically just little stickers about as thick as a credit card. (http://itsanewkastle.kastle.com/_res/u/downloads/news/Oct2012.html) The idea is that you already carry your phone everywhere so its more convenient than a fob. However, being the type that doesn't like hiding his iPhone behind a case I also don't want to have this sticker exposed on the backside of my phone. Does anyone know if there is enough space inside the iPhone 5 so that I could stick the phone tag on the inside of my phone instead of the outside?
