Have you seen the new 2-D barcode squares? They hold lots more information than the old bar codes. They can be used for products, medical info, web sites, etc. You can just point a cell phone camera at it, and it will go to the web site encoded. They are being used globally.
Revelation chapter 13 describes a system of global control. The Antichrist will require everyone to have a mark put on his or her right hand or forehead. Without that mark, the person cannot buy or sell. Included in the Mark, will be the Antichrist's number, 666.
This new bar code system may or may not be used for the Mark, but the technology is definitely available now.
