Check which frequencies a reader supports
If you're unsure about the frequencies your reader supports, you can find out using BALTECH ID-engine Explorer.
To check for a reader's supported frequencies:
Connect the reader to your computer.
I have an Ethernet reader.
To work with BALTECH tools, an Ethernet reader must be unconfigured, or required permissions must be granted in PKI Authentication and Encryption settings.
Open BALTECH ID-engine Explorer.
If you haven't installed it yet, you can download it here as part of BALTECH ToolSuite.
Check the Supported RFID Interfaces info box:
|13.56 MHz/NFC||All cards using the 13.56 MHz frequency except LEGIC cards|
|125 kHz||All cards using the 125 kHz frequency|
|Bluetooth||Bluetooth Low Energy 4.2|
