I am testing a CipherLab handheld RFID reader to scan a driver license which has an encrypted PDF417 barcode with binary data.

When I scan the barcode, I get the below string values, which obviously means nothing. Is there a way to set the scanner to not return the barcode text "as is", but rather return the barcode as a base64 string or hex string.

Return string from barcode scan:
