Lists supported barcode scanners for each Clover device (I think it's the same for all devices). I am not aware of any of them being wireless, but take a look.
Contrary to the post above, there's a difference between supported and unsupported scanners that is more than some check box on a page somewhere. Supported scanners are -not- treated like HID devices and plug into Clover's barcode scanner SDK. Apps that are coded to the barcode scanner SDK will not work with an HID scanner and vice versa. If you are writing your own app you can of course choose whatever works for you.
I'd suggest you get in touch with your business rep and request support for your scanner of interest.
