I have found the silicone bracelet the best solution for me as it blends in, similar to a fitbit or other exercise type bracelet. When I was first in China I thought to tape the catheter to my underpants, but I never did and eventually got more comfortable traveling w k pouch. Of course my medical ID wasn't in Chinese. Oh well.
I do think the directory system is a good idea, but quite honestly I'm too cheap to pay for the extra monthly costs. Have enough expenses. So glad to hear others are getting the ID. Janet
