Electronic brick - 125Khz RFID Card Reader

Does anyone have any information on the actual RFID chip that is on this brick? It looks like it’s made by ST Microelectronics and it has the following numbers

ST eZ936

I can’t seem to find a datasheet on it anywhere.

I’m trying to determine if it’s possible to have these readers indicate when the RFID tag is removed from the reader (in addition to indicating when it is placed near the reader).

Hi, you can search the name “ST358” of this chip , but this is not RFID chip .This RFID chip is “HT48F06E” . :smiley:
