Aside from my main job, I have a few other businesses on the side. One of them makes custom silicone/TPU items like cell phone cases, tennis racquet vibration dampeners, business card stands, etc. I want to gauge interest on a thin holder for the keycard. I envision something that wouldn't add too much thickness to the card but have a loop or something for valets to attach their tags. As it is now, giving them a keycard doesn't fit into their regular key tracking system which typically is a pegboard where they hang keys. As I understand it, the keycard is the same size as a credit card but slightly thinner? Can any current owner confirm this?
