I must be too old to understand any of this stuff anymore. My cellphone makes phone calls and can send texts (if I knew anyone that knew how to read or respond to a text). There is no scanner, no camera, no internet, nothing but a basic phone.
Anyhow, what do these square things do? Is there actually some information inside of it? To me it looks like nothing but a bunch of ink sprayed in the box randomly. And while I'm asking about this, what is an "APP"?
About all I can figure is that these are similar to a barcode..... But for what reason????
I'll probably never own a smart phone, since my standard cellphone is all I need for emergencies or to make an occasisonal call from my car. My computer takes care of my internet needs, and my digital camera takes pictures, so I see no reason to have any need for a smartphone. But since I am seeing these things everywhere lately, I had to ask what they are for.
The older I get, the more useless all this technology seems to be!!!! Even the internet is becoming useless as everyone leaves the newsgroups and websites in favor of Facebook, which (in my opinion) is totally worthless.
