Ode to the Bar Code

The Bar Code Book

As I do shop near my abode
And return home with my back bowed
I marvel how the check-out flowed
Due to that modest small bar code

Without it stores would soon be slowed
And industry would soon implode
With transport gridlock on the road
No more efficient way to load

It's time that honor now is showed
Praises are given we have owed
It's time that someone simply crowed
A humble ode to the bar code
