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.
