NHS Smart Cards are for staff, shirley ?
For prescriptions you just tell GP surgery your preferred pharmacy & then you can order prescriptions online, go to pharmacy, ask nice lady for prescription for A, they ask you for A's address as a check, if necessary you pay £9 ( not in Scotland, under/over age, have prepaid card, etc ), and thats it.
