Hi! I have a skipass with NFC chip (wroten information how many points left). It is secured (can I break it?) and I'd like to ask can I add points to this skipass and ski unlimited times for free?

So was anyone able to scan any NFC tags?
some stores has NFC payments enabled, some movie posters or stuff like that has NFC chip build in
in some countries there's NFC tickets for the bus/subway
so, it all really depends how popular or not it's in the are where you live
not even all USA cities are that high tech
I've heard that NYC taxis and some pharmacies and such there support NFC. But I've also heard that the phone's software isn't really setup to use the NFC yet. I know that Sprint and the Google Nexus S 4G have Google Wallet hooked up to their NFC.
I don't know that TMO has a deal with Google Wallet. Are they part of that Isis group?
I've successfully scanned my SFO Clipper card which uses NFC. Pretty cool.
The venture is now developing provisioning systems that will allow existing payments services to be added to any NFC phone owned by a subscriber to any of the Isis founder's mobile networks, says Johnson — and Isis already has a number of banks ready and willing to pay for this service. "When we launch next year we will launch with multiple banks," he explained.

I've been testing krohnjw's NFC Task Launcher app. I must say it's pretty damn awesome! It lets you set tags up for doing different tasks. I'll make a video sometime, he has some on his development page. You can set a tag to enable wifi, for example. One idea I had was to use his app to set your phone to toggle bluetooth when you place the phone in your car dock for example. Very neat stuff!

Cool stuff, time to buy some NFC tags.

I'm still looking for the best price on cheap tags to mess around with. I've also read there is some confusion around the net as to which tags will work with our phones/phones in general.
NFC Tags, what works, what does not
I've got two TMO SGS2s, so I did some NFC testing the other night. Here is what I found:
1) Creating a text tag works. Reading it from another phone works. But when read, it put the text into a new post in the Google+ app. Not really what I imagined wanting to do with an NFC tag that I read.
2) Sharing Google maps locations over NFC seems to work. But again when reading the tag, the text and URL is opened up as text in a new Google+ posting.
3) Web page URLs. I used Dolphin HD to share a few web pages. Reading the tag properly brought up the website. This one feature seems to be more or less fully operational.
4) Sharing contacts over NFC did not appear to work at all. It is an option when creating a new tag in the Tags app, but we couldn't get it to work for any type of contact.
Are you able to read arbitrary RFID tags using the T-Mobile Galaxy S 2? I've tried on several different types of RFID tags with no success (NFC was indeed enabled when I tried):
-Passport
-Building entry badge
-DC Metro SmarTrip card
I've tried using the included "Tags" application, in addition to "NFC Reader" and "NFC TagInfo".
Oddly enough, I stopped by my local T-Mobile store, and the representative told me that he was unable to transfer URLs or random tags (or contact information, as you stated) between two Galaxy S 2 devices, or between a T-Mobile Galaxy S 2 and an HTC Amaze. (We then played around with the devices a bit in an attempt to get something working, but to no avail.)

I haven't tried reading any physical tags. Only between 2 different NFC enabled phones.
I did a whole bunch of research with the Nexus S NFC reader - and so far as I can tell, the SGSIIX has the same capabilities.
I have a bunch of blank 1K, 4K and Ultralite MiFARE tags that are AWESOME to play with. Even just putting your contact card on there, or URLs (you can do anything with a URL) is tons of fun to play with. They don't read proprietary NFC implementations without special software - only tags encoded with an NDEF structure will be automagically picked up by Android.
The good stuff is coming up - I'm 98% sure that Zoompass is coming out with an Android app compatible with the QuickPay/Interact-Flash readers. Next year, pay for small crap with your phone!
Hope this makes sense, here goes. As I understand the hole purpose of NFC Tags is that you tag them with information or an action or something like that. This is then written on the chip.
My question is: Can I use a commercial tag from let's say starbucks that's programmed to open the starbucks website do something completely different without reprogramming the chip? Simple words, a program that when it reads a specific tag, like open starbucks website, it does not open the website but activates bluetooth? Or is this not possible due to security/restrictions/no way of identifying a specific tag?
In the near future I can see commercial company's handing out free tag's that can then be used for other than intended use. Recycling NFC tag's(Is also good for the environment )

no. I don't think you can do that right now.....you have to re-program the NFC chip for any new actions that you want.
However; I could be wrong but I guess you might be able to use tasker so that if it reads a certain chip it'll perform a certain action....

So let me start off by saying that I'm not sure if this is posted in the right section. I posted a thread like this a few hours before, but a mod told me to post it in App Development. He didn't tell me where in this section. If it is in the wrong one is it possible to move instead the thread instead of closing?
Anyway, my name is Gazi and I’m an 18 year old student (economics) in the Netherlands.
I’m working on a business plan for a schoolproject. We’ve got to write a business plan of a product we want to launch. After brainstorming for a couple of days I got the idea to launch a mobile application for students at our school.
For my business plan I need 2 people to answers some questions of mine, so I can get more information about the financial and technical feasibility. I would really appreciate it if you would take the time to answer a couple of questions for me. I was actually going to ask these questions to an app builder from the Netherlands, but he just called me telling me he doesn’t have any time anymore, and I need to finish this asap because the business plan needs to be finished this Friday.
It would probably not even take 10 min to answer these questions and I would really really appreciate it if you guys could help me out.
I will first give some general information about the idea of the application I have in mind:
I want to call this app ‘’App2Date’’. The purpose of App2Date will be to make it easier for students to study. It’s the solution for problems which many students are coping with. App2Date will have functions such as:
- The ability for teachers to let students know when they will not be at school, or are too late (for example, because of traffic). Many students of our school have got to travel around 1hr til they’re at school. It sucks to hear the teachers not there after having traveled for over an hour at 7AM.
- Giving push notifications of important messages on ELO (ELO is our ‘’electronical study environment’’ which is accessible via internet right now. We can see announcements teachers have published, and have access to study material such as powerpoints and word doc.s
These functions are the 2 functions we definitely want to use in the app. IF it is possible (technically and financially) there are some other features we would like to use:
- Push notifications from Osiris (Osiris is the online database with our results accessible via internet atm)
- Having access to your timetable
I understand you can not give precise answers at some questions (for example the financial ones), that’s okay’. I don’t need precise answers. I just want to have an idea of what amount of money I should think, would it cost more than 1000$, more than 10.000$, or just 200$, etc.
Questions:
Orientation
- For how long have you been building apps?
- Do you operate in some kind of category apps (games, social media, etc.)?
- Do you make applications for your own, or do you mostly make applications for companies who ask you to?
Costs (general)
- What’s the average price for building an application?
o One off costs
o Fixed costs
o Other costs?
- Is it much more expensive to build an app that is connected with the internet?
- Which criteria are most important for the price of building an applications?
App2Date in general
- What is your first impression of App2Date?
- Do you think there is a market for App2Date?
o Why?
- How long do you think it will take to build an application such as App2Date?
Technical
- Is it possible to make so many different external systems work together in 1 mobile app?
- Is this possible by linking the app to these external systems, or would it mean you’d have to build different systems within the app itself?
- Is there a function of which you think it would be impossible to make it work?
- If you would have to make a top 3 of the functions you think that would take least effort to build in the app, what would your top 3 be like?
Choose from:
Notifications from teachers who are late
Notifications from announcements from ELO
Online database with your results
Timetable
Ability to check if there are any classrooms free (this can now only be seen by the schools system)
Financial
- What do you think it would cost to build App2Date with the functions I would definitely want to use? (notifications from announcements on ELO + notifications from teachers)?
- Which functions would cost the most (and about how much? $1000, $100? Etc.)
- If you would have to make a top 3 of the functions you think that would financially be feasible the best, what would your top 3 be like?
Choose from:
Notifications from teachers who are late
Notifications from announcements from ELO
Online database with your results
Timetable
Ability to check if there are any classrooms free (this can now only be seen by the schools system)
- Could you tell me, for each function, what you think it would cost (about how much?)
- How do YOU think it would be the best to make money out of this?
Again, I would really appreciate it if you could answer these questions to me. You’d be my lifesaver. Also I didn't know if this was the right place to post this thread, so apologies if this is in the wrong section.
Thanks in advance
Please take a moment to read through this before posting, not only is a brief description of NFC and some of its uses included but also you will find a few of the more commonly asked questions. Over time these will be added to accommodate new or recurring queries that are being seen in this thread. If you have come to the thread to ask about emulating, copying or bypassing your Mifare card head down to the FAQs below .
What Is NFC
Near Field Communication (NFC) is a technology that was built upon Radio Frequency Identification (RFID). It allows for the storage of data without the need for a direct power supply. When a reader such as a NFC enabled phone comes within range (usually an inch or less) data can be read/written from/to the tag.
Objects containing NFC can be found in two varieties, active or passive. Passive devices are ones that contains data but do not read and generally will not have their own power supply. These are found in NFC tags such as those in Credit/Debit cards, Student or ID cards, Library books and passports among many. For a much larger of scannable objects see here. Their are also active devices, these can read information stored on other NFC devices and for the majority of us here these will be our phones. These active devices can also usually alter the data found on tags or transmit/exchange data with other active devices.
Uses for NFC
NFC has many uses both commercial and on a development/hobby level, here are just a few:
Contactless payment
Transfer of data from phone to phone
Share and log on to WI-FI
Sharing contact information
Automating tasks
Storing bitcoin wallets
Disabling alarms
Send Wake-On-Lan commands
FAQs
How can I emulate, copy, edit or bypass my Mifare card (student ID, work ID, Bus pass etc)?
The short answer: you can't
The long answer: There are numerous reasons why you may have had issues finding this information on XDA. Primarily because it is not possible from the vast majority of phones and for good reason. Mifare as mentioned above is a security layer for NFC cards and therefore the process isn't as simple as just downloading an app, scanning a security card and then forgetting about it. Secondly depending on the type of tag you are trying to use this is either A) illegal or B) against your companies, service provider, school's security policy and as such you will not find this information on XDA.
Your options from here are: look elsewhere for this information, just use your card as instructed or speak to your IT department about adding another form of NFC tag to the system, I for instance have an NFC tag implanted in my hand which my IT department was more than happy to add to my user profile at university. More information on this can be found here.

How can I make Android trigger an event when I scan an NFC tag?
For simple commands you can use apps such as NFC Tools or Trigger.
For more complicated tasks a combination of Tasker and Locale can be used to launch just about any chain of events upon finding a specific tag. Of course alternatives do exist, so be sure to check out a few of the other projects around the site

Hi all,
I'm new to this forum. I registered here because I'm looking into NFC tags to try and create a certain project... So I would like to pick your brains to see if what I 'm looking to do is possible and if so what it would take...
I'm basically looking if I can use NFC tags in a mentalist effect as I'm into magic as a form of entertainment.
I would like to apply NFC tags to a bunch of small items that are displayed in front of me, all within range of my phone (or if need be another NFC reader). Then, while I am not looking, I would like one of my spectators to pick up any object they choose so the rest of the audience can also clearly see what object has been chosen. Yet by doing that, the chosen object would go out of range for the NFC reader. Obviously the spectator would then place the object back where it was. he or she would also be allowed to slightly move all other objects so it wouldn't be obvious which one was picked, as only one object is not in the exact same spot it started in...
I was hoping that there is a way for an NFC reader to scan multiple NFC tags in a reasonable amount of time and then also detect which tag isn't there anymore when the spectator shows the chosen object to the audience. Because that would then give me the chosen object. (the way I see it with my very limited knowledge by scanning all NFC tags within range and comparing that to a database that holds all tags that should be there. This should result in one that's missing)
So, is the above possible? Can NFC technology be used to scan a known library of tags and then identify the single tag that is missing?
If so: what are the limits? How many tags can be scanned let's say within 30 seconds? (like 5, or 50 or 100?) I truly have no idea.
What reader and tags would I need? How would I be able to have the NFC app tell me what tag is missing? Can this be an audio message I can receive through an earpiece?
What would be the maximum area all remaining objects should be in for the reader to be able to pick all of them up?
Is there a minimum distance needed between the tags to be able to read all individual tags or can they be very close together?
Any other constraints I missed?
Thanks a lot for letting me know,
Kind regards,
Peter
