Background: We have a project were we want to be able to assign a scanned RFID to an object in a database. The scanners, using Bluetooth, will vary wildly, but will use either UHF or LF, but at first pass, we couldn't see a way to tell the difference. The reader itself or the tags themselves, don't seem to attach any extra data regarding this. So we've resigned ourselves to having a manual toggle in our software.

But are there other ways?

Aside from frequency ranges being different, is there something inherent to a RFID tag that tells us if it is LF or UHF?

Since your host doesn't interface with the tag itself, it's up to the reader to do that.

I'm pretty sure they somehow give you that info. Or a certain scanner type can just read one type of tag, and that will tell you.

This isn't something you can solve in software.
