• Organizing the Mechanism of My Card Key

  • My student ID card, cafeteria ticket, dorm room card key, and key to enter university buildings.

    • I’ve probably done it about 7 times in the past six months.

    • I think Creating a Device to Remotely Turn Door Knobs would be the best option for this (including the fun aspect).

    • In the past two times:

      • First time: It fell off when the lanyard was broken.
        • This was the fault of the broken lanyard.
      • Second time: The holder for the new smartphone I was trying was loose.
        • This was a problem with the product.
    • This is a problem with the management method.

      • Maybe it’s better to just use a lanyard normally.
