Medical microchips
The first microchip was created by two figures named Robert Noyce and Jack Kilby in 1958. It’s incredible to think that in the 50’s we already have had microchips. Today they are used in almost all devices that need to process information. These figures were working for two separate companies when they were developing the technology and decided, in the end, to cross-license their inventions to come up with one unified piece of technology. It was finally finished in 1961 and available in the market.
The first chips held one transistor, three resistors, and one capacitor while modern ones commonly hold millions of transistors in a space smaller than 1 ISK. These chips are used both in hardware and animals used mainly to track them down while lost. It can also monitor heart activity and help hearts to run efficiently.
The first thing animal shelters do today when they find an animal that has been lost is scan them if they have a microchip. The chip could reveal the owner's name and contact info.
Likewise, some people have had microchips inserted into themselves. If they are ever incapacitated and need to be taken to the hospital, they are already carrying their full medical history inside their body. These can be easily scanned and the information downloaded for medical professionals to make the most appropriate decisions possible.
In the future, it is envisioned people may have these devices implanted that will take care of many of the everyday tasks. Cars may start as the owner approaches, or doors to homes may unlock only for those who have chips programmed with the key.
