Then ponder implanted RFID credit cards, and agree that there is no reason to implant payment information. Of all of the cyber-implants one could get, I don't really see a point. Something that transmits payment is something I'd prefer to leave at home- or be able to put in a static bag. Especially when digital-pickpocketing becomes possible when RFID making tools hit the market. Already, there have been cases of Ez-pass "theft"; people scan the ez-pass of people in parking lots and encode that onto their own ez-pass. RFID credit cards would be even more lucrative.
Finally, I think these guys are joking, but they've got some good ideas anyway: Holistic computer medicine. Actually, a quartz wrapped in cat-5e cable sounds like a good idea to me. As does the meditational wait states.
