ISBN Specifications
ISBN (International Standard Book Numbering) bar codes are essentially
EAN-13 with a 5 digit supplement, where the first 3 digits are the Bookland
country codes of 978 for books and 977 for periodicals. Although the bar
code contains 18 characters, the ISBN format uses only 9 of them, along with
a newly calculated Mod-11 check digit. For example, a bar code containing
the numbers 978055337062153495 would transmit as 0553370626 in the
ISBN format.
The RF Terminal has the option of transmitting in the ISBN format.
