Read rfid 125khz and NFC using esp32

Projects General Guidance
1

I'm planning to build an access control system using an ESP32 microcontroller and integrating RFID 125kHz cards along with NFC technology. However, I'm facing a dilemma regarding sensor compatibility. Is there a sensor available that can read both RFID 125kHz cards and NFC?

My objective is to allow different users to utilize either RFID or NFC for access control purposes. For instance, some users might have RFID 125kHz cards while others may prefer NFC-enabled devices.

I've come across the PN532 sensor, but I'm uncertain whether it has the capability to read both RFID 125kHz cards and NFC, or if I need to choose between one of them.

Any insights or recommendations on compatible sensors or how to approach this integration would be greatly appreciated.

Thank you!

What does the PN532 datasheet say?

First page of PN532 data sheet lists 13.56Mhz and NFC support.
It does not support 125khz.
