iPad is a scanner.
The fastest, easiest and most efficient way of getting a document digitised I've found in almost two decades of educating and web-developing is iPad.
It took me ages to scan a document using my 'traditional' scanner.
I first had to uncover it from under the stack of office documents that had accumulated in the office corner.
I switched it on. It took it's time booting up, warming up and finally start zzzaacking at me.
I already had the document I wanted to scan inside the scanner.
I pressed the 'scan' button.
It squawked at me. Then it began slowly sliding a glowing blue bar beneath the glass panel my doco rested on. It made it to the end of the machine, aackked again, and retracted noisily.
I lifted the glass panel... my scan was complete!
The process of 'scanning in' a document took ages and made lots of noise.
It took me only a few seconds to take a scan of this page using my iPad.
I used the iPad camera.
A "scan" of something essentially means you're looking to DIGITISE it.
Then you'll do something with that image in the digital world (email, edit, or store it). Or you'll print it out.
You can do all that with your iPad.
Three taps and it's done. A few more taps it's eMailed to where you need it. It's high resolution, can be inserted into documents on your Mac or PC, and can be sketched on using the right apps, compiled or just stored for posterity.
The Camera App on your iPad is a very handy tool NOT JUST for taking pictures.
Having a camera allows you to digitise data almost instantly, and make use of that digitisation in fun or productive ways.
