I'm not sure if this has ever been implemented yet, but can you imagine a way of paying with Bitcoin by just using your own body? It would be more of like a microchip implanted into your left or right hand that would contain both your public and private keys to send and receive Bitcoins. So in case you want to send or receive some BTC, you would just pass your hand over at a scanner and it would perform the desired operation. This is would make it a very convenient and easy way to transact, and carry your Bitcoins with you anytime, anywhere. However, the only thing to be considered would be the security of your private key from within your implant, to protect your funds from theft. Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency.  |

As long as is not bad for the health, and is just a microchip that you can carry in your belt this would be an awesome idea.

Besides the obvious problem with security this sounds like a lot of science fiction, but i see no technological problems. So this could be available even today. The question is why would you want that? How can you make money if you offer such services? I just see no need and many risks.

Yeah, I remember reading about that article about some guy that already did the first payment with his hand or something like that, throught a chip that read a QR code or something. The thing is, it's pretty stupid thing to do in my book. In the future once bitcoin is 1 mansion per coin, you are asking for some robber to your hand and use it to go shopping..

before anyone does it.. may i suggest that people first buy a NFC sticker that they attach to a wrist watch/band first.
much like getting a fake tattoo before going under the needle and trying it for real
i know a few people use it as a way to unlock a phone. and do other snazzy things and others are envisioning a way to access other things. but here is a security thing to think about:
if you want to use implants/nfc to do things.. have the code/message changeable, not permenant. EG when you wake up you scan your wrist to update the code/message in the chip from the safety of your home. and that sets it to be valid for that day. and have it change each morning.
the reason is because people can easily walk/brush passed you in public and read the data and simply emulate it. so having the data permanent is BADDD.
what people have done is use a known keypair where the service knows only the public key. the chip stores just a daily "signed message"
EG
"its 20/12/2016 i own 1abcdefg..."
which is verifiable to the public key without revealing the private key. because the privkey is not part of/stored on the chip
nfc chips are not sophisticated enough to receive data and then instant sign it, (hence manually daily updating required).
but it does open up opportunities..
years ago i did suggest blockchain.info had their login method set as a public key where blockchain.info displayed a daily message and people would need to reply/paste/input a signed message to confirm they own the registered publickey.
(research BitID)

I don't think the whole idea about chips under your skin is a good thing.. I mean c'mon you could use a Trezor or even invent a better hardware wallet for all people care, but you know if we start messing with our bodies I think we'll see some terrible mistakes at the near future (transhumanism).

Sounds a lot like Revelation, referring to the Anti-Christ's mark. "And he causes all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name" “If any man worship the beast and his image, and receive his mark…the same shall drink of the wine of the wrath of God…” |

I'm not sure what to think about it. This idea that I carry some chip in my body reminds me on some kind of surveillance and some science fiction movies. Probably it would be very practical and secure but it doesn't sound attractive to me at all. On.the other hand there are no guarantee that this chip couldn't be used for some wrong purpose. I'm not against inovations, on the contrary, but I wouldn't do this.

This idea is fitted at malls, replacing the cards, having a microchip in your hand will be convinient cause you don't have to carry your cards. The main problem here is not about your private key but the fact that why would someone have to implant a chip in his hand for that purpose, Carrying a card or two is not really a problem. The project is nice but I don't see any advantages of this that is worth it enough for people to have their hand implanted with a chip. Problem number two is its health risks. If there is, then it will not be worth

interesting, i didn't know that exist already, it would be cool if it was possible to scan the eye to do a transaction, but i guess it would be more dangerous, also if a guy like him will carry his phone anyway, i see that it's better to just use that to pay |

The idea is good, but I would not like to have an implant in my body to be able to receive and send my bitcoins. This implant should cause health issue, or in the case that you take the airplane, do you need to change the mode  So the next generation of wallet will be a human wallet in the future! |

Such advancements were not needed. Because one in ten uses such methods for easy accessing. This looks like a step ahead than the ongoing development. The coming generation might give preference to these kind of fantasy based usage of bitcoin and other digital currency with the hand acting as a wallet for all needs.

imagine it. having to have an implant to get a job.. then sacked 3 months later because its a mundane stupid 'mall cop' job. now you have to have surgury to get the chip out. yea easy to inject in. but getting out.. um not so easy and no employer would pay a sacked employee for hospital treatment, so not really a positive thing in places like malls that see a high turnover rate of staff. but for anyone thinking of the oppertunities/possibilities.. stick with nfc stickers that attach above the skin or on things.. not under the skin |

We're not far away from that kind of system anyway. We know paper money is not long for this world. There are a couple of obscure companies researching biometric scans (such as fingerprints and retinal scans) as a method of debit card replacement but there are flaws in implementation left to overcome. The expense of the very sophisticated equipment is a big one. It's likely the only countries that could easily implement something like that are small ones with a strong technological infrastructure. They've even looked at the possibility of a blood pressure and pulse detection system to determine if the body part being used for payment is on a living person and that person is not under duress (to eliminate theft). |

NFC/RFID use residual energy to send out a predefined message.
if someone can work out the actual microvolts needed to receive message(a), sign it and send message(b) and develop a small/safe nfc/rfid that can do some basic 'processing' such as signing a message using edcsa keypair or bitcoin keypair. then they can be in for alot of potential as a possible new industry
until then ... manually updating the stored 'message' daily/weekly/random time is the only solution. though better than biometric data (isues with papercuts/dirt ruin fingerprints, cateracts retinal scarring(diabetes) ruin retina scans), its still better to have a identifier that can change per day/use.

No, it wouldn't. Sounds a lot like Revelation, referring to the Anti-Christ's mark.
"And he causes all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name"
“If any man worship the beast and his image, and receive his mark…the same shall drink of the wine of the wrath of God…”
No problem. We'll only install it in the left hand. Then we can avoid an early second coming and we can all do business without fearing "the wine of the wrath of God". Simple solution. |
