Manufacturer of the RFID sensor?

Anyone know who the manufacturer/part number of the RFID sensor is on the GHI module, [url]https://www.ghielectronics.com/catalog/product/366[/url]?

@ GHI - Can the sensor be purchased separately? I need to install on a custom PCB, so using the pre-assembled module would not be ideal.

@ munderhill - Sorry sir, that is classified information… :whistle:
