Now I Have an RFID Implant I Have No Idea What to Do With

Most implants simply aren’t that useful. Magnets are a popular implant, but all they do is allow the body to sense magnetic fields, a neat party trick without much practical use. (One grinder said she was able to diagnose a problem with her grandmother’s electric stove with the help of her magnet implant. Another incorporates the implants into her day job as a Vegas magician. In one trick, a magnet in her hand powers a lightbulb.) Plus, implanted magnets encounter problems so often that having one removed is practically a grinder right of passage. Using your hand to start your car or unlock your front door with an RFID is cool and perhaps even practical if you’re someone whose always losing their keys. But those chips have limited memory, and many systems are incompatible with one another, making it a guessing game what will work and what won’t.
