Sharp's Tiny LCD Doubles As Scanner
morpheus83 writes "It's all of 3.5-inches but this LCD screen from Sharp features an integrated optical scanner that could be used to scan business cards, but also be used as a method for multi-touch input. The prototype was seen at the Ceatec exhibition. Possible uses include the ability to recognize fingers or other objects and as biometric lock on your phone. And since each pixel has a scanner it may as well be a multi-touch screen."
The summary is the entire article.
Could give POV a whole new meaning.
In Soviet Russia, LCDs watch YOU!!
Please place your face on the monitor so we can take your picture.
Didn't Apple already patent something similar, in which the screen was also the camera or scanner? In Apple's case, it uses the dead space between each LCD pixel to be a camera.

This so reminds me about the old support joke about a user trying to send a document, by holding it up in front of the screen. :)
So is this your deep desire to accuse others of your own problem?
hahaha the word penis is so hilarious! i applaud your wit good sir!
Hey, I know, let's see if you can feed the trolls! You douchebag.
The use of this LCD screen as a fingerprint scanner will most likely suffer from the same problems as all fingerprint locks. They rely on the "something you have" principle as an authorization token. Until, that is, someone removes your finger from your hand.
Also, fingerprints are per se not exactly unique. Ask the lawyer who was misidentified as a terrorist for having similar fingerprint features.
And of course, it is not exactly difficult to copy and fake someone else's fingerprint.

Here's a link to a 2003 white paper for the Society of Information Displays that explains the tech completely and much more than the article http://www.planar.com/advantages/whitepapers/docs/Planar-AMLCD-Optical-Touchscreen.pdf
I'd say more, but my guild is raiding.
rofl ahahah i agre parent foor the win fuck u, u exactly, u fuckurs who take dis serisly. thats a good joke :DDDDdl,lolololahahalolololeelehe that showd u
From the article And since each pixel has a scanner it may as well be a multi-touch screen. Am I the only one who remembers TV screens that provide the surveillance video back to the big brother?
This touch/scan/display is exactly the kind of tech needed to make transparent back/touch devices practical. The back side doesn't really need the display part, so the entire device can be cheaper.

If you were to put these touchscreens as the primary UI on vending machines, ticket machines, ATMs and the like, you could harvest hundreds of thousands of fingerprints without anybody realizing it. I bet that we'll see more and more companies trying to con people into "use your fingerprint to make calls, pay for your shopping, access your ATM" type of deals. I also bet that these screens will wind up in cellphones as a "standard" feature. You'll be told that you can switch scanning off and use it only as a touchscreen if you like, but who knows whether the scanning function is on or off and whether the phone is sending your biometric data places without your consent or not. This tech is a definite threat to privacy.

Tell me when they make LCD pixels that double as a display, a video camera and loudspeakers.
I was going to start some form of worldwide control and surveillance movement, but can't really be arsed to stick a TV, a separate video camera AND a pair of speakers into one box.
It's funny, they create this advanced technology to scan "business cards" when people should just figure out how to transfer their entire contact information by IR or bluetooth. Another solution looking for a problem. If people can't figure out how to do something as simple as an IR transfer from their cellphone, then how the heck are they going to figure out how to scan a business card, run OCR, make edits/fixes, and import that into outlook?
Monitors for women! No need to go anywhere to check up on your hair, just switch on "mirror" mode. Of course, I don't think the cameras will be that good, but I am excited about being able to hold paper up to the screen and then throwing it in the recycle bin.

Yes. Yes you are. The only person on Slashdot smart enough to have read 1984. Well done!
No, you're not.

In Sharpiet Booth, LCD screen reads you!
Assuming these things have a high enough resolution, QR-code already solves the problem of embedding contact information on business cards in a machine readable fashion, without the need for OCR. A lot of cellphones these days support it, and it seems to me that being able to scan cards using one's monitor would be a nice extension of this sort of technology.
Your point is still valid though. People need to have a certain level of proficiency with technology in order to be able to utilise even QR-code, and if they're at that level then sending a contact card via bluetooth is probably just as straight-forward.

made me remember a post from here over a month ago. It was even stranger when I discovered this post is a dupe of that one.

No sig for you! Come back one year!
Sorry, that didn't work. I know I should have checked it but hey, it was my first post. Here it is again:

I made an April's Fool press release back in '96 about the ability to scan Post-It notes by holding them up to the screen. Finally, science catches up with my bold vision!
