TecTiles security?

Here's a good resource:
NFC Tags - XDA-Developers

I would stick with Type 2 tags and stay away from the Mifare Classic tags because they "may not work with all future NFC devices". I bought the Outdoor Type 2's for added flexibility:
tagstand - Outdoor Type 2 NFC Sticker (PVC) - Circle (30mm diameter)

Allright, so what do you need to do to program these on the S3? Can u use the tectile app?

You should be able to use the TecTile app, but since I won't have my SGS3 for another week, I can't say with 100% certainty. Otherwise, there is a list of apps in the link.

Hi. I guess I am a newbie here.

My VZW S3 should be here next week, and there's talk of 10,000,000 S3s being sold I am really interested in getting some TecTiles, but I am also concerned.

Do they create a security issue? Can someone else take control of my phone or get my information through their TecTiles?

Like if I am on a crowded bus, can someone have a TecTile in their bag that programs "send out accout information" or "send contact list" that will control my phone? Can they turn on my "hotspot" (without buying my dinner first!!)?

Thanks

Me: Can you list what type of tags are compatible for the Samsung Galaxy s3(NA version)
Tagstand: All of them! I would reccomend the Mifare Classics though if your'e being choosy
Me: Thank you for you're reply. Why would you reccomend the mifare classic?
Tagstand: they hold the most data!

I corresponded with Tagstand regarding what NFC tags to get. Here is what they said:


I went to Samsung's site to get more info on the specs of their TecTiles and heres what i found:
Specs - Cell Phone Accessories ETC-TT1G6N | Samsung Cell Phones
Some key specs I noticed:
MIFARE 1kB NFC memory chip, 100,000 cycle Write Endurance, 10 yr Data Retention, 13.56 MHz Operating Frequency

So with that said, I think the Mifare Classics should be ok. That's 752 bytes vs 144 bytes. Only thing is the Mifare Classics can't be made Read-Only.

While this is true, it should not be forgotten that not all apps have to write data to a tag.

Some apps, just read the unique tag ID and let you save the commands you want to the phone. Thus making the tag data size redundant.

Keep in mind that 'typically' four commands will take up an actual data size of 40-43 bytes, and in some cases, some people only use 2-3 commands at once.
1k tags will hold a lot more commands, but do you really need them to for your own personal uses, is the question.

NTAG203 tags, will be more than suitable for the needs of Joe Bloggs, if good old Joe insists on actually writing info to the tags instead of using an app that just reads the tag ID and activates a profile.

I ordered mine from TagsforDroid yesterday. Hopefully they are here a couple of days after my phone arrives (the 9th). The only reason I ordered from them was because they have the android logo on them and also send a free key chain nfc.

Are you going to put a tag on your keychain?
