Don't know anything about magnet implants.
A local radio DJ had an RFID injected into his hand about 5 years back as part of an on air bit. It was free, took a couple seconds, and was almost painless. He could do all kinds of cool stuff with it like wave his hand over his car and it unlocks. Only down side is they found that it causes cancer. So he had to pay a couple grand to have it removed. Seems to me magnets in the fingers could cause a similar problem. We aren't really talking about modification here, we are talking about adding a foreign substance to the body. I would do some serious research first.
