Overview

Telepen Numeric is a variation of the Telepen barcode that allows for double density encoding of numeric values. This results in twice the packing density.

Encoding

Telepen Numeric encodes 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Structure

Telepen has the following structure:
  • A start character.
  • Message encoded.
  • Check digit. - modulo 127.
  • Stop Character.

Requirements

To meet conventional printing requirements, Telepen barcodes have a wide to narrow bar ratio of 3:1. Telepen contains no inter-character gaps, but the specification allows them. The Telepen barcodes generated by Toolkit do not contain inter-character gaps. Toolkit automatically calculates and applies the checkdigit.
