Answers to Questions
How to encrypt using Barcode Codabar cipher?
The Codabar Barcode format is used to code mainly numbers. However, it contains 9 other symbols: -$:/+.ABCD
Each character is coded with 7 bands, of simple width (1 = narrow) or large width (2 = thick) alternately starting with a bar and ending with a vacuum.
| 0 | 1111122 | 1 | 1111221 |
|---|---|---|---|
| 2 | 1112112 | 3 | 2211111 |
| 4 | 1121121 | 5 | 2111121 |
| 6 | 1211112 | 7 | 1211211 |
| 8 | 1221111 | 9 | 2112111 |
| - | 1112211 | $ | 1122111 |
| : | 2111212 | / | 2121112 |
| . | 2121211 | + | 1122222 |
| A | 1122121 | B | 1212112 |
| C | 1112122 | D | 1112221 |
Example: The value 0 will be drawn 101010001110 with 1 a black bar, and 0 a white bar / empty space.
A complete barcode, begins and ends with a letter, this allows several combinations of letters possible in order to distinguish different products or applications.
The Codabar standard does not include a checksum.
How to decrypt Barcode Codabar cipher?
The deciphering of the Codabar Code consists in the binary reading of the bands, the detection of narrow and thick ones then in their translation via the coding table.
Example: A message 10001011101 translates 1211211 (1 = narrow, 2 = thick) and corresponds to the number 7
How to recognize Codabar Barcode?
