check-sum verification: the checksum of ean-13 is optional and made as the sum of the numerical value of the data digits.
max./min. code length: each symbology has own max./min. code length. they can be set to qualify data entry. if their max./min. code length is zero, the global min./max. code length is in effect. the length is defined as to the actual barcode data length to be sent. label with length exceeds these limits will be rejected. make sure that the minimum length setting is no greater than the maximum length setting, or otherwise all the labels of the symboblogy will not be readable. in particular, you can see the same value for both minimum and maximum reading length to force the fixed length barcode decoded.

format
isbn/issn: the isbn (international standard book number) and issn (international standard serial number) are two kinds of barcode for book and magazines. the isbn is 10 digits with leading “978” and the issn is 8 digits with leading “977” of the “ean-13” symbobolgy.
example: barcode “9789572222720” - output: “9572222724”
example: barcode “9771019248004” - output: “10192484”
