Yes, I do attach something like this to my traveling coins and bugs.
Go to your trackable items and select one. On the right-hand side under the "Trackable Options" section, you'll see something called Print Info Sheet. Click that link.
I copy this info sheet, shrink it down just a bit, print it, and then laminate it. I then attach it to my traveling item in the hopes it will help limit missing coins or TBs. It may not prevent theft, but it may help deter it. Hope that helps!
Edit to Add: Be sure to upload a pic of your coin or TB. This pic will show up on the info sheet.
