As Atilla said, walletmor may be an option since you live over there but ide also like to explain why samsung pay may not be the solution:
Samsung pay works by blasting a magnetic field at the swipe terminal in the same sequence that the reader would see the magnetic bits in a magnetic stripe from a card. The problem here is that that mag blaster as ill call it, is actively powered. It doesnt take power from the field emmetted by the reader and modulate it for comms, it just feeds off the phone battery to blast away.
This presents a problem because an implant of such a device would almost guaranteed need to be active and therefore require some sort of battery. At this point in time, batteries are a big no-no for implants for a couple of reasons but number one is that if they fail in any way it could be deadly.
TLDR: samsung pay does not use nfc for its payments to my knowledge like google pay does and would be prohibitively difficult to implement safely
By the way, if i got anything wrong here please correct me
