Program  Raspberry Pi to take input from RFID reader and outputs (plays) a sound via a speaker (Bluetooth connectivity preferred)

Logic:

A plate with embedded RFID reader.
8 Rocks with embedded RFID chip. Each rock has unique RFID chip.
A Speaker (Bluetooth)

The plate continuously scans for RFID chips nearby.
user places Rock “A” on the plate
RFID reader scans the chip and outputs a corresponding sound via a speaker.

When Rock “B” is added to the plate, the RFID reader scans the new rocks chip and outputs another sound via speaker

Note: as long as both rocks are still inside the plate, both corresponding sounds will continue to play via a speaker.

(Imagine music keyboard. Where pressing one key makes one sound but pressing another key adds another sound to the output)

This requires programming raspberry pi such that the RFID reader embedded plate  is constantly scanning for nearby Rocks.
Once a Rock is removed, then the corresponding sound will stop playing.

I have raspberry pi computer. Need recommendations:
1.  for type of RFID reader and RFID chips required.
2.  And Any other components required. (USB Bluetooth speaker, I/O devices etc)
