Fingerprint account

There is an unknown account belonging to a recently deceased person. Shortly prior to passing the deceased was going to pass on the account which is probably a safety deposit box to a family member but there was not enough time in the end. The only clue is the deceased mentioned a finger print would be required.

I would assume there are very few locations in the Republic that offer this service.

How could I find out these locations as there is no will and no directions were given.

Thanks.
