contactless RFID / NFC michrochip. fited under the skin in your choosen position.
" Security notice:
Although it is difficult to steal information from an RFID chip, particularly one that is sub-dermally implanted, some people still have concerns that criminals at very close proximity can easily use scanners or NFC-capable cellphones to wirelessly scan the data from chips. For this reason, some have opted to use RFID-blocking wallets and RFID-blocking sleeves. The wallets are obviously applicable to credit cards and other non-implanted RFIDs, and so are the sleeves, but you can technically wear the sleeves over the hand, or have them under a glove if you still have concerns about data-theft and want to take extra precaution. Extra precaution that you really don’t need, but understandable if you think you do. " biohackinfo.com
