Recently I saw a post where someone was looking for something like
this, unfortunately I can't remember who it was!
Just this morning an elderly relative of mine who has Diabetes fell
when their blood sugar was low, I was looking online for something
for him.
universalmedicalid.co.uk
Based in Bedford.
This company has a wide range of items, some of which can be
engraved with a unique user/pin no. This is linked to the wearers
medical information.
