(Q) How to test the NFC?

In here, there isn't Google Wallet payment nor any kind of NFC payment.
How to test the NFC?
Is there any NFC transmitter thing that we can order for testing?
I live in the Netherlands. I have never heard NFC being used here.

I've used this to test my octopus card
https://market.android.com/details?id=com.nxp.nfc.tagwriter&feature=search_result

Thanks. Lucky I still have some octopus cards from my trip to HK.
I read some tags with no problem, but some cards even though detected, it said not supported and cannot store data.
And I don't want to mess up with the other octopus card because it still contains some money.
Hmm...

the GNexus currently can only read pre-formatted tags IIRC
you might want to check out the Apps/Themes section as there is a bunch of NFC stuff over there (just search NFC)

NFC card

Is it possible to copy the contents of my office punch card into a new NFC chip. I am planning to buy a set of 100k NFC tags and was hoping to copy the contents of my punch card on it and keep it at my desk since I often forget to bring my punch card. My nexus can scan my punch card and save it but I can't make heads or tails of it. So is it possible? I know its not possible to beam that data onto the card reader for now from nexus device.

Don't know what you trying to achieve, but if you are trying to emulate your door card using the gnex, i can say in a thousand years.

No, I know that technology is not present yet but can I make a copy of the door card using gnex and NFC tags?

Nah, you have better luck asking someone related to security on how the access card system works.

Can a device be used as an NFC tag?

If so, can I copy the code from a certain tag and have my device replace the tag?
Here is what I mean:
Let's say I am in a hotel where they use cards with NFC to unlock the doors. Can I use a special software to copy the code found in the NFC tag inside the card and then have my phone "project" that code with it's NFC capabilities? The result: Unlocking the hotel door with my phone.
I am generally speaking.
Thanks,
Oren

Think there's an app for that.

And that app might be...?

There seems no APIs for notifying detection of external RF field to apps. So, probably it's impossible.

I don't know what exactly you want to do,but this URL should put you on the right track not to mention it works great.DL Check out Samsung ezon door locks, they use NFC and the link below is Samsung's way of letting you clone the code to your phone so it can be used instead. Works over RFID, now remember say a work card or hotel as you said. Well unless the hotel happened to have 0 security for encrypting or shielding there RFID unlock code in this case, similar to the defcon hack. Then it would not be as easy to implement. So yes it can be done providing you have access to the master key in effect or there isn't any security. Things such as gwallett as everyone knows uses the secure element in our phones to keep someone from getting someone elses wallet info.

Not necessarily.
Any SD card should in theory work, as long as its under 64GB
BUT
I still wouldn't buy an off brand or generic card because their ****, and watch out for fakes! I bought a 32GB Kingston at a flea market one time. Was a fake, corrupted 90% of the data on it as soon as it transferred.

You should do some reading man. You can put apps on any SD card using apps like AppMgr, App2SD, etc.

Thats the thing ive tried app2sd and other apps they have trouble moving it on the s4

Isis Mobile wallet.

Verizon made Isis Mobile wallet available nation wide today and it supports all the newer android phones except the one. Even the dna works. Any ideas why the one was excluded and can it be hacked in at all?

Must be the Secure Element SIM card that's required. Apparently, there's not one for Verizon. Fail.

What? The if the SE is in the SIM how can there not be one?

Isis DOES (DID) work on the One. I had it working a couple months ago, totally stock.
But apparently they updated it and it took compatibility away from the One. So now it doesn't work.
Not sure why they would do that...stupid stupid stupid.

you shouldnt use ISIS out of principle.
google wallet should work, no?

How can one tell if they have an se sim? I have one that came with my One and it looks different from the one that came with my S3.

I do not believe there is a way to tell. When I ordered my s4, I asked them for the NFC Sim because the customer rep said that i would need it for my wireless charging (I wasnt going to tell him otherwise!) And it looks the same as the other sims Ive had in the past. Since having the HTC One, Ive used the sim and it looks the same as the one that technically came with the phone

Here's an image from Google.

Anyway since we have 2 methods of getting Google wallet working there is no reason to use Isis in the first place.

There's not one. Verizon doesn't provide one for the One, AFAIK.

My SIM looks a lot like the NFC SIM in the picture.

HTC One does come with NFC sim. At least mine did. (see attached picture) Plus, Isis was working for me when I first got my One, then all of a sudden it wasn't compatible. Very weird. I mean, it's not like I'm missing much, the only isis places around me are Coke machines... hah

For everyone having issues with ISIS and haven't seen already, you can now get Google wallet working with tap and pay which is a much better app anyway.

Weird...I have 4 phones on my Verizon account, 3 Galaxy S4, 1 HTC One. On two of the Galaxy phones, there's an option on my device manager page to order the NFC Secure SIM. There's no such option for the One. This seems to be consistent with what I'd read elsewhere on XDA, but if that's really a secure element SIM, then cool. I think I'll contact Verizon to see what's up.
Meanwhile, Google Wallet is working great for me. :good:

How are you getting tap to pay working? I have a SE sim card but google wallet isn't saying anything about tap to pay. Also NFC is turned on as well

Do it exactly according to the instructions. Worked for me. I've used it at Whataburger and Academy just fine.

Update:
According to this post: http://forum.xda-developers.com/showpost.php?p=46926490&postcount=29 - there is an NFC Sim Card, and I checked mine - I have one. So...cool.
Now - why can't I use ISIS? I can't even download the app from the Play Store.

Thanks! I guess I should have searched a little before asking

Hmm...Google Wallet tap and pay works fine for me on the One. I too was told without the secure element it would never work. I guess my SIM supports the secure element as I use Wallet almost everyday. Of course, I'm not stock

So according to all the blogs, the small update the VZW One got was supposed to enable Isis support.
I updated, but Isis still says my phone is not compatible...
