Waveshare, known for e-ink components aimed at hobbyists among other cool parts, has recently released a very interesting addition to their product line. This is an enclosed e-ink display which gets updated over a wireless NFC connection. By that description, nothing head-turning, but the kicker is that there is no battery inside the device at all, as it harvests the energy needed from the wireless communication itself.
Since microcontrollers and e-ink displays consume a very small amount of current compared to other components such as a backlit LCD or OLED display, this harvested passive energy is enough to allow the display to update.
And because e-paper requires no power at all to retain its image, once the connection is ended, no further battery backup is needed. E-paper is notorious for having very low refresh rates when compared to more conventional screens, much more so when driven in this method, but there are ways to speed them up a bit. If home automation in the IoT era has taught us anything, it is that no one wants to run wires. Many of us rent, so new cabling is not even an option, even if we wanted to go that route.
If you want a unique sensor, you have to build your own, and [tmkThings] wanted an NFC scanner at his front door. Just like arriving at work, he scans his credentials, and the door unlocks automagically.
NFC hacks are great because they are instantly recognizable and readers are inexpensive, but deadbolt hacking is delightful in our books. When [gdarchen] wanted to read some NFC tags, he went through several iterations.
First, he tried an Electron application, and then a client-server architecture. This sounds easy, but there were quite a few tricks required to make it work. But the biggest problem was enabling WebUSB support.
Once you fix those things, the rest is pretty easy. The PC side uses node. If you back up a level in the GitHub repository, you can see the earlier non-Arduino versions of the code, as well.
If you want to understand all the logic that went into the design, the author also included a slide show that discusses the three versions and their pros and cons. He did mention that he wanted a short-range solution so barcodes and QR codes were out.This process will allow you to reset your filament nfc tag to a full configuration using an Android Device with NFC.

Please forward this information to me and purchase my eBay item at eBay Listing. I will provide the key to you through eBay, then you can follow the rest of the directions. The alternative to the eBay listing is to use a process where a logic analyzer is physically attached to a chip inside of your disassembled printer and listening for the key.
The eBay listing is a way for me to get your password, so that you don't have to purchase various electronic, learn to use them and take apart your printer and make connections to your printer chips. By all means if you have the desire and or the equipment get your own password go for it.
I'm just providing an alternative. At this time the procedure below shown in the instructable linked below for 2. At this time no one has reported getting anything to work to roll back from 2. Other then that please just experiment and if you are successful post a comment or let us know on the forum.
At this time we are having issues with getting the correct reset values for firmware version 2. Just be warned that this firmware may be recording something on the tag and length and giving errors when the number ends up higher. We are working on figuring out what it is recording and if there is data set that will reset it, but at this time we have not figured it out.
It seems to happen to chips that have been run all the way to empty, do not run any chip you want to reset to empty, reset before you hit zero. Also, if you have the choice don't upgrade to firmware version 2. It is known that on at least one Android device the phone identified the tag as a MiFare Ultralight instead of what it actually is an NTAG as can be seen in the picture above. While the information included in the picture can be forward and the key can be found from this info, the app was not able to use the password due to the device identifying the tag as the wrong type.

In this case the tag was taken to a different device where the key was then used successfully. If your device identifies the tag incorrectly be warned it may not be able to use the key to read and rewrite the tag.
You may need another Android device or something else like an Arduino and NFC shield to read and rewrite.
This means that pages 3 to 15 of the tag are irreversably locked and can't be rewritten. And pages 10 0A in hex and 11 0B in hex which has the original reel length can't be increased.Back in the day, we had smartphones with physical buttons. Not just power, volume, and maybe another button on the front.
It was a lawless wasteland, but for those who yearn for the wild-west days of the late s, [Liviu] has recreated the shortcut buttons that used to exist on the tops of these keyboards for modern-day smartphones. To recreate this, he went with a few NFC tags. These devices are easily programmed via a number of apps from your app store of choice, and can be placed essentially anywhere. In order to make them visible to the phone at any time, though, he placed the tags inside a clear plastic case for his phone and can now use them anytime.
Plus, you could easily upgrade this project to allow the tags to do any number of other things. You can take projects like this as far as you want. Ahh, toddlers. Each block has a magnet and an NFC tag.
It also tweets the song selection and artist. The blocks themselves are quite beautiful. The Song Blocks demo video is waiting for you after the jump. NFC tags are cool, but programming them to do your bidding — whether unlocking your computer, making an Arduino vending machine, or a smart home application — requires using an NFC device to program the tag over the air.
What if you could just wave your hand and transfer money that way? Well [David] did, so he decided to do something about it. He made the vending machine in his hackerspace, FamiLAB, cyborg friendly. But first, why is [David] even doing this?
Is he a cyborg or something? Wanting to take the most advantage of these augmented abilities, he put together this clever NFC credit card emulator.
This means building a an NFC tag he can turn on and offan interesting problem to say the least. Now, with a press of a button, [Per] can activate his NFC tag and pause the music in his new stereo.

E-paper is notorious for having very low refresh rates when compared to more conventional screens, much more so when driven in this method, but there are ways to speed them up a bit.
When will someone come out with a cheaper competitor for e-Ink? How long are technology patents like this, 15 or 16 years? I think the real cause of the price being fairly high is lack of competition, caused by lack of demand. Or higher in res. Colour depth is fine with 16 greys which will do for still images. Actual colour never worked out either, nor did better refresh rates. Those bistable LCDs are better for almost every other purpose. There lies a lesson. The biggest mistake with e-ink devices has been making them too smart, too feature rich, too processing powerful.
Most people already have a quite capable computer in the pocket and do not long for yet another expensive device to charge frequently, more app stores and accounts to set up, etcetera.
I agree. The technology lends itself best to low-feature devices where the display of infrequently-changing information is really useful. It is just like wireless charging for a cell phone; you still have to have the charger plugged in on the desk.
You save 1 gesture, but one that only happens at the same time as other gestures you still have to do, like interacting with the phone to cause it to display a charge level. Or to display an error message even after the device is turned off, until it is cleared! I can easily imagine a shelf of parts bins with labels that can be edited by an app. Something a rich person with OCD would really enjoy using, but is going to generate more ridicule than interest from the average person.
I could accept the e-ink display price if i could find cheap driver board for it. You can find 9. This is actually used in stores to update the price tags along the shelves. I saw it in use first time around 10 years ago, but then it was powered by a tiny solar cell. Nowadays they removed the solar cell and the tags are updated by NFC. This is actually pretty old stuff.Here's what to keep in mind as near-field communications NFCthe technology that allows Apple iPhone users to tap and pay, takes off.
By the end ofmore than a billion phones will have the capability to use the wireless protocol to exchange data, and applications beyond payments will become common. In an annual hacking competition of mobile devices in andsecurity researchers used previously unknown flaws in the NFC functionality of smartphones to compromise devices. NFC, based on contactless smartcard technology, allows secure data exchange by using encryption and a special processor. In addition, the wireless technology limits communication to within a short distance, reducing the opportunities for an attacker to eavesdrop on communications and adding security and privacy.
Yet, while the NFC Forum claims a read range of a few centimeters an inch or soacademic researchers have extended that to about 80 centimeters about 31 inches —a much greater distance for attackers to play with. Already, home automation aficionados have used NFC tags—small devices capable of storing and transmitting data—to allow location-dependent phone settings.

Contactless conference badges are a common use. The smart card technology on which NFC is based means the data on the badge is secure, and the close proximity required to read the card usually satisfies any requirements for the user to opt in. At amusement parks or on cruise ships, NFC can be used to manage access to rides, venues or other attractions. With a credit card transaction, most people understand that a handful of companies—the store, card processor, issuing bank and credit card company—will get some information on their buying habits.
With NFC, however, the picture is less clear. The application developer and the service provider may also get information. The NFC vulnerabilities used to compromise devices in the Pwn2Own competition have been fixed, but manufacturers are typically slow to release patches for vulnerabilities in smartphones. NFC is new, and many consumers have yet to adopt the technology. Aside from saving some power, turning off unused networking features is a good rule of thumb to limit exposure to attackers.

Latest Post: 10th November AM by midoAll you need to do is receive your device close to an NFC chip to read the data on it or execute tasks.
But the NFC Programs apk goes further and allows you to tool tasks on your NFC tags in order to automate actions that were once boringly repetitive. Turn on the Bluetooth, set an alarm, control the volume, share a WiFi network configuration and so much more.
For example, a easy motion with your smartphone in front of your NFC mark before going to sleep and the WiFi will turn off, the smartphone will switch to silence and your alarm will be set for the next morning, all by itself.
Quite practical, isn't it? For the most tech-savvy of you, the geeks : preset variables, conditions and root tasks are also accessible so you can make more complex actions. Make your life easier with more than tasks accessible and unlimited combinations. The "Read" tab allows you to see data such as: - the maker of the mark - the kind of mark ex : Mifare Ultralight, NTAG - the norm of the mark ex : NFC Forum Kind 2 - the accessible technology ex: NFC A - its serial number ex : cab - the size of the mark and of the data on it - if you can write on the mark and if the mark can be locked as read only - all the data on the mark NDEF format The "Write" tab allow you record standardised data such as: - a easy text - a link to a site, a video, a social profile or an apk - an email - a contact - a smartphone number - a predefined text notice - an address or geolocation - a WiFi or Bluetooth configuration - personalised data.
The write function allows you to add as much data as you wish. This method you can record really big quantities of info on your tag. Other features are accessible under the "Another" tab, such as copying, erasing and password protecting your NFC tag.
The tasks allowing you to automate your smartphone are under the "Tasks" tab and are categorised. A Google user: I loved using this apk for its easy UI design. Modernize: Only problem i noticed is that writing to my NFC mark occasionally fails, but most of the times it works. Maybe because i am using a little place mark 18x18mm. WTJ Zhuo: Good and helfull program 5 star This apk are Clearly not for dummy.
Joe Putz: Works good. Just want Android device gave permission to toggle mobile data. Maybe marshmallow modernize will fix this restriction. Eric Doucet: I have the xnt implant and this apk works good for it. Lava Git: Thank you for this well designed apk! P I: I really have fun using this apk. Its easy to use and straight forward.
Vlad Hiottu: good! Vadio Gitazy: This is the right program, what I was looking for. Bert Reuling: Easy, informative. Steven Bordengo: Simple to use with my fresh tags from amazon and so cool! Stephen Ledet: Works good! Col Skinner: No frills, simple to use perfect apk. All awesome. A Google user: I like thie still learning. Ubaid Rehman: both thumbs up. Tony: i installed this to setup a list of tasks for my smartphone to do when i use it on my bicycle nfc mark on the smartphone mount seems to work perfectly.
Lucas: Nothing more or less than everything it needs to be without anything additional. This Dev could create all the apks.
AMVLiv: Great. I read all my cards and it works excellent!
