I did this for my child with an ESP32, RFID cards off ebay, and MP3s on a SD card. A fun project.

Tip: it's much quicker to read the serial number of the RFID card and rename the MP3 than it is to program the MP3 name to the card!

Depending on the SD card formatting, perhaps a nice big folder of symlinks.
