Is that like a card game similar to top trumps or yugioh interesting I'd like to see this in action
The background to Barcode Battler is -
It was created in 1990, released in 1991, and went world wide in 1992/3.
The game converts barcodes into Heroes and Enemies (which can be either Wizards or Warriors).
Wizards can use magic spells, Warriors can use Weapons and Armour items.
The gameplay is very repetitive and simple - you can choose to either attack or heal on each turn after scanning in your fighter and power-up.
Essentially, it is a very basic version of Yu-Gi-Oh or Pokemon, and it predates both

I am in the process of making a new card set (not a trading card game, so Wizards of the Coast cannot sue me) for the Barcode Battler which uses some of the lesser-known aspects of the machine, such as enemy stat reduction, use of fighters as power-ups (as a Gang-Up option perhaps) and other bits, but if you don't like the Barcode Battler in the first place, you probably won't like my expansion either.
There are many places to find a Barcode Battler - your local second hand game shop, online auction sites and even certain Barcode Battler specialist sites have them for sale.

Some people might want a barcode generator on their site if:
They own a Barcode Battler, Scannerz or other barcode game site
They want to print a lot of barcodes off for catalogging stuff with a standard barcode reader
They are fascinated by black & white stripes
I would never encourage the use of my generator for creating cheaper barcodes to put on expensive items as this constitutes theft - another site has encouraged this and has been shut down.
Barcodes are quite easy to research and understand - my previous barcode generator used JavaScript to display a series of 13 to 17 images next to eachother, but this was unweildy. The php solution creates a single image.
For my own purposes, I created the barcode generator to act as a web counter on my site, as well as to provide me with working barcodes for my new Barcode Battler game.
The Barcode Battler reads the generated barcodes and gives the same results as equivalent barcodes on bought goods.
No, this is one of the few serious things I have posted recently.
Thanks for the Korma.
I'll help anyone who wants details on building images using PHP, as this can be a little tricky. The commands are similar to some of those in Yabasic though.
