Timeliness[edit]

This page has some seriously out-of-date information, especially in the pilot section. I would like to update the page by doing the following: adding a paragraph about NFC tags; significantly increasing the industry application section with both existing and emerging applications; and updating the pilot programs and service launches. Nearly all of the pilots date from 2008 and earlier and thus are no longer relevant. I would update pilots with only 2010 and 2011 data, delete all earlier and unreferenced programs, add references to all programs so that they could be updated and verified more easily in the future. In addition, I or someone else should set up a new section for multi-country deployments, as a few providers have announced such initiatives. ˜˜˜˜ — Preceding unsigned comment added by Rfidwriter (talkcontribs) 19:42, 27 April 2011 (UTC)

Many references are out of date. NFC has evolved so rapidly that even year-old references can be out of date. This article is written as a computer science advocacy paper instead of a reference. The opening paragraph needs to be understandable by all. Much information is given without citation. No History section is given so the article is a tangled web of information. I will attempt to make the opening paragraph more readable and up-to-date and add a History section to make it more understandable.— Milominderbinder2 talk 17:08, 14 June 2011 (UTC)

Security Risks[edit]

This article does not address in very much detail the security risks of 13.56MHz and NFC - it does mentioned NFC has a serious eavesdropping risks. NFC is not permitted in any secure areas in the USA. Several cell phone manufactures have not been too enthused to adopt this as a standard because of this risk. IEEE 1902.1 is the only wireless technology that has approval for use in secure areas within the US and is in widespread use. It is true that a large percentage of the NFC signal is magnetic (about 40-50%) but what this article does not say is that at 13.56Mhz about 60-50% of the energy is an electric filed that has the ability to travel long distances. If you measure voltage on a loop antenna the E portion of the field drops off at 1/r, while the H (magnetic) drops of 1/r3. If you measure power the E field drops off 1/r2 and H drops off 1/r6. Bottom line is the E emissions provide a NFC security risk. The only way to eliminate eavesdropping risk is to eliminate E. NFC was concerned about bandwidth so decided to compromise security to get higher bandwidth. Have examples of conventional 13.56 Mhz RFID transmitter being detected 20 (twenty) miles from its source, even though the RFID tags only have a range of about 3 feet. Glad to discuss physics of this with any of the NFC group. Can assure you possible to monitor NFC signals at a distance and many papers confirm that. Most of the academic studies do tests with low cost equipment, but history has shown if money involved bad guys will develop expensive state of the art equipment and use.

I will add a section to this that I think will be balanced and objective - many articles and concerns on this topic on web - great white paper on NFC from Phillips discusses above as well.

Just because you operate in near field (usually means much below 1/10 wavelength) does not mean you don't emit far field detectable signals.

Does anybody know how this is related to RFID? --144.82.240.6 15:09, 12 July 2006 (UTC)

I don't like the style of this article - it reads like advocacy. Wikipedia is not a soapbox

Reverted to older version. Article was a copy of http://www.nfc-forum.org/aboutnfc/ 129.27.203.169 09:07, 4 May 2005 (UTC)

NFC is RFID, or better LF and HF RFID is always NFC. UHF RFID can operate as near field communications (at short distances i.e. in a printer) but is normally used as far field communications. --Rfidguy 01:49, 5 September 2006 (UTC)

I find some important information missing in the comparison with bluetooth: is NFC capable of talking to other NFC capable phones directly? Bluetooth is. For RFID the reader is a special device. If yes, if only one of the phones is powered, is it also capable of powering the other one (just like RFID)? —Preceding unsigned comment added by 194.171.252.100 (talk) 13:10, 20 January 2009 (UTC)

External links[edit]

I nuked the list of external links in the article because it's gone far, far beyond the point of being useful and into the deep end of spamcruft. Following the advice of WP:SPAMHOLE, let's start the section over. Here are the links I removed:

Let's pick a few very good and solid links that pass Wikipedia:External links out of this list to put back in the article. The company links can be left out, since Wikipedia is not a links directory or vehicle for promotion. — Saxifrage 22:23, 14 October 2006 (UTC)

Added an image, we have more explanatory images if required. --Timoarnall 13:46, 5 July 2007 (UTC)

List of trials[edit]

I've updated the list of NFC trials. The list is not complete as new trials are announced every week however I've tried to put a list as much accurate as possible. Curiouscitizen 10:37, 14 August 2007 (UTC)

List of trials[edit]

New update of the list. I have removed the projects of SEP (Bulgaria) and m-pay (Poland) because they are Mobile payment project based on SMS, not NFC. Curiouscitizen (talk) 16:23, 7 December 2007 (UTC)

I would remove all the trials which does not have a reference. What do you think? Some of them are just a list of companies. --Ivanmilara (talk) 15:31, 16 January 2009 (UTC)

Notes and references[edit]

I have renamed the References section to be (foot)Notes and introduced a "proper" References section to hold the list of reference works (books, articles, etc.) to be used to support citations. I have also included a reference to an article to support the claim of distance "up to 10cms".--Михал Орела (talk) 09:22, 24 October 2008 (UTC)

It would now be a good idea to move relevant stuff out of the (foot)notes and into the references section proper. This will take a lot of work.--Михал Орела (talk) 09:28, 24 October 2008 (UTC)

The moving of Timo Kasper et al. 2007 from footnotes to references took about 30min. :-) But, it was a complicated reference and difficult to get right.--Михал Орела (talk) 10:04, 24 October 2008 (UTC)

Any volunteers who wish to continue the good work might like to look at Citation_templates

What should I do?

Don't panic; you should have time to contest the deletion (although please review deletion guidelines before doing so). The best way to contest this form of deletion is by posting on the image talk page.

  • If the image is non-free then you may need to provide a fair use rationale
  • If the image isn't freely licensed and there is no fair use rationale, then it cannot be uploaded or used.
  • If the image has already been deleted you may want to try Deletion Review

Tidy up[edit]

At present, this article is a bit of a mess. It seems to have a "kitchen sink" approach, filling every section with all manner of external links, uncited quotations, non-sequitur factoids, and "wouldn't it be cool if?" sentences, with no coherent structure or explanatory aim. (Indeed, when I first read it I couldn't even get an idea of what NFC is, just what it could be used for.) I've tried to remedy this at the beginning (in the lead and in the "Uses" section), where I think clarity is most important. A similar approach is needed in much of the rest of the article, if anyone else is up for it... -- Perey (talk) 07:52, 11 December 2011 (UTC)

Application[edit]

A cell phone representative said grocery stores in the USA will soon be equipped with this technology so you just swipe your cell phone and some toll roads are already equipped with the technology. 108.81.134.236 (talk) 03:26, 23 February 2012 (UTC)
