This is very easy
HOWEVER
you will need a tool of some description to do it.
A PM3 or Flipper can do it easily.
This is a very good option.
My guess is, you ate in NZ or Australia.
(in my experience, Gallagher is quite common there)
What do you want to write it onto?
DT used to offer a copy service.
If you want it written to an implant, Amal MAY offer this option.
