I actually have a couple of working Skannerz!

My most favorite type of Kmart gaming.

These were so fun! I barely understood them as a kid but still had a blast scanning stuff for monsters and items

I totally forgot about "Skannerz"!

Thanks for rushing back a bunch of my childhood memories

Back in the early 2000s there was a Jurassic Park III-adjacent game that used the same gimmick. It was called Scan Command and the idea was the bar code scans would give you genetic parts that you could use to upgrade your dinosaurs. I very quickly found out you could use a thin blanket and rub the scanner back and forth over it to get as many parts as you want.

Nice little nostalgia hit right here.

This video has a pretty good skannerz joke in it

I had a Barcode Battler. I loved it. Looking back, I guess the fun came from the book that accompanied it along with creating my milk, cereal, or soap themed heroes.
