I have one of those keycards for work. I only need it to get into the building in the morning but might need it if I leave. Here is the problem. I had it on a key ring and it broke, so I drilled a hole in it and ruined the magnet that lets me in. I can’t wear a neck lanyard because of the machines I work with. How would you carry this every day so you don’t forget or loose it but it is still accessible? it is the size of a credit card.
