If there is a problem in reading a PDF417 on the card, the reader reports an error using the ASCII string “ NR ”
(HEX 45 & 52) followed by a character
indicating a type of error. The error types are:
“ 0 ” : Not found a PDF417 symbol
“ 1 ” : Too many damaged code-words
“ ” : Too many Misread code-words
“ 3 ” : Codeword translation to ASCII error
Any enabled prefixes or suffixes are appended around this message. The reader does not send the Code ID
even in case that the option is enabled.
