Smart Cable Counter Flycase

Hello,

I work in AV industries where we use a bunch of cables.

One of the worst part of the job is to count each cable we put back in the case at the end of the gig.

I got an idea about that : a flycase who’s count how many cables of different length they actually get in through a ink display for low consumption. RFID look like the only solution to scan those cables.

Where I’m stuck is the how rfid can read the whole content of the box and detect any new or removed cable from?
Have you an idea ?
Thanks

Read the weight.
That's how the correct money comes out of an ATM.
