Human Microchipping

Human microchipping is the practice of inserting a glass encased transponder under the surface of the skin. These implants are already currently used widely to identify pets such as cats and dogs, and usually contain identifying information that can be scanned using radio frequency identification (RFID) or near field communication (NFC), both of which utilize radio waves. In humans, it is possible that these devices could be used in a wide variety of scenarios to increase ease of use for everything from accessing bank accounts to starting cars. While they are already quite popular in Sweden, where one train company recently experimented with microchips serving as tickets, there are several concerns with the security and ethicality of widespread human use.

How They Work

RFID transponder and NFC microchips are currently most widely used. They store a single unique identifying number that can only be read by specific radio scanners. Once brought into proximity, the scanner can read the identifying number and access a secure database where the individual’s information is then brought up. Notably, RFID microchips only work in one direction, where “data flows from the tags to the reading equipment” (Chandler). NFC microchips, however, can be used for both one and two way communication. In 2 way communication, the chip is able to send information to the scanning device beyond just an identification number. This can be utilized to quickly and rapidly share information and link devices. For example, a doctor could attach a NFC device to you that could, using your cellphone as an intermediate, give them real time health data on you (Chandler).
