No Satire here. The thing about the magnet in the finger is that you can not only feel metals or other magnets but with it beeing implanted near a very sensitive nerves you can feel alternating magnetic fields, for example transformers, electric powerlines etc. Thats something a magnet in my pocket cannot do. That beeing said, my magnet got rejected pretty fast and i chose not to reimplant it after that since i also had problems typing with it.

My argument for a magnet, even though it might lose magnetic power over time, compared to an RFID Chip is that the magnet implanted gives you a new sense that you cannot get without implanting it. Compared to a rfid for paying which can be replaced by a phone/watch/card without losing functionality and magnets aren't going to become obsolete by the whimps of a bank or cc provider.

That sounds like the worst experience ever, it would be like giving yourself touch tinnitus.

Oh no it's super harmless. You can only feel it close to a source like when you feel your hand along a wall with an embedded wire running main AC. The only time I was genuinely surprised by it was when i walk past a motor in a train that was starting up but even then it wasn't annoying.

I prototyped a glove with hall effect sensors and vibration motors to allow sensing magnetic flux without needing to implant a magnet in your finger.
