Here’s a cool technology developed by Xerox. If you have any classified information, you can probably by benefit from this technology. There is also a way to decipher XEROX codes which are hidden in your XEROX prints. Another good point is that the paper can be used over o
Okay, here’s a way you can store information on paper. All though it’s not in commercial stages, this seems like a technological breakthrough for storage of information. We might actually travel back in time to the beginning of computers where paper was the storage. Let’s keep our eyes keen on the
