How to:

Read the Barcode on ID Badges at
Ruston High School


The barcodes on the ID Badges at Ruston High School ar= e encrypted in what is called Numeric Code 39. It is simple to read if y= ou know how. You will discover that, once you have read the barcode, it = is your Social Security Number. It is illeg= al to use Individuals' Social Security Numbers on publicly used ident= ification cards, badges, etc. (Social Security Act =A7205 [42 U= .S.C. 405(c)(2)(C)(i)-(viii)]).=20

The Barcode is made up of a starter digit (*), a data set (your Social Se= curity Number), and a finish digit (* again). Below is a sample Barcode.=

The narrow bars are 0s, the wide bars are 1s, and each wide space is tran= scribed as "-". The barcode above would be transcribed as:
0-011010-00101-00111-00000-10110-10001-10000-01110-01001-0100-0110

Now the code must be broken down into five-digit sections as follows:


0-0110 10-001 01-001 11-000 00-101 10-100 01-100 00-011 10-010 01-01=
0 0-0110


Each five-digit section is a code in the list that follows.
0   00-110
1   10-001
2   01-001
3   11-000
4   00-101
5   10-100
6   01-100
7   00-011
8   10-010
9   01-010
*   0-0110  starting and ending digit (ignore)
Now try to decipher the above barcode. The accurate results are posted <= a href=3D"123-45-6789.html" target=3D"_new">here.
