This was an enjoyable read. My GE fridge uses RFID for keeping track of when to change the water filter. This isn't really an area I'm familiar with but I'm curious how much I would be able to figure out with the right tools.

In GE's defense, limiting the amount of time you can use a water filter for is probably a good idea considering what the filter media fills up with if you do nothing.

The OEM filters cost like 2-4x what a suitable generic costs. Would have been cheaper for GE to add a software feature to warn you after 6 months and allow you to reset it.

There is a much simpler solution, buy the bypass plug which has the rfid chip in it for about $50, cut a chunk of plastic with the chip off being careful not to harm the antenna, and tape it to the inside of the fridge in the same area. Only downside is you have to use your brain to replace the filter with a compatible one every once in a while, and it says “not filtering” on the front panel when you dispense water or ice.
