Looks like Device::USB was last updated in May 2017 (about a year ago), so may be up to date enough for your purposes.

Most RFID readers output a stream of bytes. An USB unit might present that as a virtual serial port, in which case, you might be able to just open the associated tty/serial/COM device and read the data via a file handle.

Or, it could present as bulk data. If so, you would need a module like Device::USB.

It is even possible for the reader to present as virtual keyboard. Under Linux/Unix/POSIX, you could open the associated device and read the data via a file handle (though, I think you will get scan codes). Under MS Windows, I don't know how (or even if) to access different keyboards as separate devices.

I would plug your reader in and see if you get a virtual serial port or keyboard. If not, Device::USB will probably work.
