I have a scanner that looks exactly the same and works perfectly on Mac.
Essentially this device works like a USB keyboard, and thus requires no special operating system or driver support.
The device is NOT supposed to show up in The Finder sidebar, contrary to other suggestions here.
To test the device, open Notes, TextEdit or similar app - then scan a tag with the scanner. The number should show up (make sure you can enter numbers with your normal keyboard - i.e. a text input area needs to be in focus).
If it doesn’t work it can be an issue with the port, cable or similar. Check System Report to see if the device is reported as connected on the USB bus.
Update: After you have added the USB information from System Report to your question, it is clear that the hardware you have is a non-standards compliant "China clone" (for example the vendor code is 0xffff), which does seem to be USB HID, but not emulating a keyboard.
In this case, you will need a driver. It seems multiple people have had problems getting this device working on Linux, and someone used a lot of time reverse engineering the Windows program supplied with the device, as the manufacturer is obviously not interested. You can download the Linux software here:
It uses libusb so it can probably be compiled and works on a Mac as well. I haven't tried though, as I haven't got the exact device you have.
