The code.
July 22nd, 2009
One of the most innovative stuff that always caught my attention is barcode scanner. I wonder how it works but it really smart and advanced. Each time I see the cashier point the “gun”, it keep me wondering how that kind of laser can detect the “code” that embed on the mercahandise’s box.
Sometimes, I feel like our life has been change totally. Technology is keep updating and what will happen 20 years from now? Only time willl tell.
