This is probably the best solution to your “where did I put my wallet” question, implanting it in your hand!
Martijn Wismeijer (Mr. Bitcoin), the Bitcoin entrepreneur out of the Netherlands implanted a tiny NFC chip under his skin, developed by a company called Dangerous Things.
It is compatible with all NFC compliant devices such as mobile phones, tablets, etc. and can be used to launch URLs, share contact details, unlock phones, etc. The chip can also be used with several types of commercial readers to unlock doors, start cars, log into computers.
NFC (Near Field Communication) is a wireless system that enables devices to send, receive data, send commands to other devices and make mobile payments.
When asked about the reasons behind the implant, Wismeijer said:
I did it because I wanted to experiment with storing Bitcoins using sub-dermal implants,I thought it would like be the Holy Grail of contactless payments.
