I love this site https://www.vegetablefarmer.co.uk/medical-netcom-39b0.pdf yourmedpack.co.uk  I don’t see how this fixes the flaw. It sounds like it just alerts the user, who will most likely ignore it or be confused by it. It also doesn’t fix the case you suggested of a person plugging your phone into their charger with an “oops I thought this was mine” because they would just tap to accept the charger.
