Magnetic or rfid music box Answered

Hi,

i was wondering..is there any possibility to make something like this:
you all know the sound mats for kids, where they step on it and it has a sound box in it and plays a sound..i was wondering if those mats can be modified like this: instead of playing sound when you step on it, it should play sound when you put an object over it ( magnetic or rfid).

any idea if it works and how and what is needed?

Thanks!

Yes they can.

You'll need an RFID reader/mag switch

In the case of the RFID reader you'll need additional electronics to check the card then trigger a relay or transistor switch to activate the mat.
