If you are looking for information about the barcode on the HMP device (e.g., for stocktaking purposes), see the HMP identification page.
Any barcode reader / scanner, connected via USB and with standard HID keyboard emulation is theoretically compatible with the HMP. These devices present themselves in the same way a keyboard would and can thus be used for a basic lookup in a local list or even into a remote database (some coding would be required for this case).
Note: USB devices requiring custom drivers are not supported for security reasons.
