# ACRBuzzerControl
Control device buzzer when an NFC card is detected. ACR122U or compatible NFC reader devices.
I bought an ACS ACR1252 NFC Dual Reader on amazon. By default the reader buzzes when it reads a card. You can use this tool to disable or enable this behavior.
The full API for the device is here:

Kudos to Daniel Mueller for his great PC/SC wrapper for .NET (https://github.com/danm-de/pcsc-sharp).
