I bought this as a test unit before eventually ordering another brand for a project at work. As the description says, and the reader is also screenprinted, this seems to apply to Windows only. It was not recognized by two different Macs. It emulates a HID keyboard, so I'm not sure why that matters. The reading range is a bit lower than expected and there were problems reading some classic Mifare tags, which the brand's other readers had no problem with. You'll notice a sea of doubles on Revain, but they have subtle differences. This reader was also slightly larger than others I've purchased.
