I am surprised that nobody has yet mentioned HP inkjet printers and the RFID chip embedded in the refill cartridges.

- rahimnathwani 7y agoWhy do they use RFID instead of exposing the contacts (like on a SIM card, or other ISO7816 card)?
- chrisseaton 7y agoPhysical contacts are usually the flimsiest part of a system aren't they? Probably costs more as well to have connections! RFID is so cheap they put them in paper clothes tags.
- SketchySeaBeast 7y ago> Physical contacts are usually the flimsiest part of a system aren't they? Sounds like a great way to sell some more ink or another printer early.
- mrb 7y agoNot necessarily. I used to always buy genuine HP cartridges, sold by Amazon (not a third-party seller,) with official packaging, non-tampered unbroken sticker on the box, and yet one day my printer reported a cartridge as "non-genuine" and absolutely refused to accept it. Maybe the chip malfunctioned. But since that day I have stopped buying genuine and I replaced them with recycled third party cartridges. A third of the cost. And they never caused this problem. A defective system caused HP to lose a customer.
