HP Labs developed a new rewritable printing technology

I wonder why people haven't done this before. The e-paper displays have always been the 'epaper' layered over circuit that creates tightly controlled electric fields. I'm guessing its something about the registration between the 'display' and the 'writer' that has fairly high tolerances. If they could license the plastic logic process to make plastic versions of the e-paper then you could have "paper" that you "print" but can recycle just by sticking it back in the input paper tray. No money selling ink though :-)
> When a card is placed in this imager, a simple bar code on the back of the card uniquely identifies it to the HP IonTouch system, allowing the imaging device to retrieve whatever new information needs to be placed on the card.
(also seems a little backward that I wouldn't just send the info to the printer and then put on/in the card I wanted to print/re-print.)
Maybe I'm reading too much into that, but I'd be surprised if it's totally innocuous. But, then again the research and capital investment needed to make this happen deserves to be rewarded, imo.
Hard to imagine how much they'll charge for a printer. Especially if it has no toner to run out... and each card can be printed 10,000 times.
Each card costs "several tens of cent" -- that struck me a marketing person trying a little too hard to downplay the cost. But, the die sublimation printers needed to print color on plastic badges are $10k+.
Side note, whatever happened to color e-ink displays?
True color E Ink displays with multiple colors in each pixel were thought physically impossible, but first prototypes were shown last year. I suspect we're relatively close to a production version.

Do you have a feeling what it takes to push down color e-ink prices down to affordable (sub 1k for 32") levels? An order auf 10 Million? 100 Million? At what scale does this work?
I wonder what's so innovative about this. E-ink displays consist of 2 parts. The actual display is essentially a bunch of bubbles with liquid in them. Below them is an electrical grid that can create small localized magnetic fields.
When developing these things they are often made separately for testing. The display is a card, I saw a laminated card approach, and you simply put it on top of the electrical grid. Add some tape, and the display works. This is simply someone realizing, hey, use that test process and we have a "printer" and has long been foreseen as a potential application. Issue is that the chemicals are expensive.
Also, the printer knowing the mapping between badge# and image to show might be more convenient. For example, consider a case where a badge shows what areas personnel is allowed to enter, with that changing per day (cleaning personnel in high security buildings, or visitors from competing companies who have meetings at multiple locations across several days for example)
In either case, you could give them a badge and let them check out and check in without human intervention.
I would expect HP will try and lease out the printers, though, charging $X per month plus $y per print.
Maybe you have different classes of cards, like VIP, regular visitor, employee lost badge, etc. They all have different looking "shells".
So this setup makes sure the right data is printed to the right shell. Allows two different people to do the data entry and "printing" with less coordination too. No worries about FIFO, just print everything in the in bucket.
If it's based on the same electrophoretic principle as regular EPDs, which seems to be the case from reading their description, then they will be affected by strong electric fields.
The concept itself is not particularly novel (this is just the electrophoretic sheet inside an EPD, with the electrodes in a separate writing head), but I think this may be the first time it's been productised for this particular application:

ePaper is cool because it is dynamic. Without it it’s just really expensive paper.
And I don’t think this can scale to replace paper recycling. Reuse like that to be viable would have involve mechanical feeding for example. I’m guessing this is also probably heavier and thicker. Never mind that, again, why wouldn’t you just use an eInk reader instead.
Am I missing anything here?
I think they are overstating the security aspect though. You wouldn't need to recreate the tech to mimic one of these. Actual paper behind clear plastic would probably look similar if you experimented with paper color, print color, some kind of bezel effect and the plastic overlay.
You just described regular paper.

Trying to decide if this is deliberate or a bug where each page load does some kind of reload(s) of itself.
> They also added networking and cloud integration to the system, enabling the Linux-based IonTouch imager to link with customer-owned cloud databases. A retailer, for example, may recognize a customer’s gift card as it runs through the imager, immediately debit it for a purchase, and then print the new balance on the card along with a discount for a product relevant to the customer’s previous buying habits.
... imagers that are both extremely reliable and yet are “hot swappable”. “If you have any problem with an imager, our cloud backup system ensures a fast replacement. Just swap in your spare imager, authorize it with your password or code, and off you go,” Gila explains
Also, if used for security badges, how will this prevent others from rewriting them using a separate printer?
There will be other niches though, one mentioned is public transport e-money/fare cards having the fare updated and promotional advertising. I can't see that happening though as this would be too slow to move through a gate compared to a NFC card. From a transport operators point of view they are unlikely to want move back towards a system where the fare gate ingests, prints and ejects a card. Have you seen the inside of a fare gate for dealing with magnetic cards? More mechanical parts than your average pinball machine, a wonder of technology but really nowhere near as reliable as an NFC reader (picture at http://www.industrytap.com/japan-railways-automated-ticket-g... and illustrative video at https://youtu.be/MIzekUVPdgY). And of course NFC is getting more availability on mobile phones so the fare card will disappear into the mobile.
And of course, there is paper, mighty cheap and comes in fancy colours :)
Edited - add ticket gate image and video
Not saying this channel is a bad idea! I'm just the kind of guy who likes breaking things to see how they work. Criminals are almost always one step ahead because they see things in ways others might not imagine. Those errant use-cases are the ones to try to bulwark against...better when for fun than when the stakes are really high, know what I mean?
These would still need whatever separate RFID or NFR tech is used to swipe and open gates, doors, etc.

So that's the flip side, an escalation in confidence factor - oh this is new and it's not as exploitable! - is perfectly reasonable at first. I'm not trying to be sarcastic about this, but I remember reading that some crew found an exploit in pacemaker protocols (e.g. connectivity) that could be manipulated if a person had bad intentions. Who sits around and tries to figure out that kind of stuff?
Oh, right, guys like me sitting in their garage. Spiritual kin of Woz.
My kidding-but-not-really musing is that I've been an employee of 12+ different companies in my life, and I've seen how things work in practical terms.
The biggest security penetration vector that can't be digitized is human behavior, because if you act like you belong and your badge looks like you belong, yippee! Now you've got physical access, and that's 9/10s of any penetration objective. I mean, if I was a KGB agent, that's how I'd think about these things...
