I could see a physical bitcoin kinda like MintChip using this type of tech. It would be good for small amounts using Electrum or Stratum purchases.
From what I have heard. MintChip sucks.

Could NFC or Near Field Communication be the next big that Bitcoin needs for offline exchange of Bitcoin?
Thoughts?

Nope, NFC is more insecure that QR. QR is low tech but if implemented properly, can give you decent security and it is easy to use and it open sourced. That has a lot of advantages. I still think NFC will take off but I personally will not use it and I request all my cards without that RFID tap and go stuff removed.

Well, I think the cell phone industry is trying to equate the "nearness" aspect with security. IMO, these sorts of things should be done as an open, patent free (or fully donated) standard and welcome people to bang against it.
NFC is just a slightly more convenient way to move small amounts of data between devices. It's useful but nothing revolutionary.
You can do offline payments with QRcodes+Bluetooth too. We prototyped it in Berlin on Android.

Corporate Bullshit which translates into Proprietary RFID tech.

It has limited applications so far .... I am with you.
Are you suggesting that some people think that if you put secrets in the clear in a QR code or send it via NFC it makes it secure? I don't see how anyone would think that.
I do not have a percentage for you of how many would "think like that", but those who are not "nerds" could easily think that. We are still in the age where governments of nations still use 12345 as a password.
It's like saying English has been cracked or something. Are we on different wavelengths here?
edit: The sane use would be to send someone a public key and amount to pay, nothing sensitive. Are you thinking about a different use?
English could be used for an example. If a person is from China, English is a "code" to them that they can hear, but can not "decode". Only someone that understands English can "decode" and "download" ( to their brain ) the information (data).
A QR code is something a person can see, but can not decode. It takes a machine to do the decoding. The machine takes the encoded information in the QR code and displays something we ( or another machine ) can use. Humanly speaking, that is translation.
But the example does not yet enter into encryption. A QR code that is encrypted has another layer of encoding, similar to adding pig latin over English.
You'd think payment methods would have security high on the goal list.

NFC costs more than ink on paper.
But they are REUSE ABEL.
You mean to go back to wherever the NFC sticker is posted , reconfigure it, check it, repeat ?
That cost something. If you use QR code you are piggy backing on existing logistics (magazines, billboards).
Conversely, the marginal cost of adding a QR code is virtually zero.
Plus if you want a crypto processor in the NFC tag, you are up to $5 a pop (ex works, no logistics included).
Oh, and one last thing: wait 3-4 years before NFC phones make serious inroads in terms of market share.
Ohhh scary title. For a moment I thought this would be a story on some type of mind-melting QR code.

What do you mean crackable? They are just ways to send info.

QR codes are not secure if they can easily be photographed. In marketing this is desirable to have them photographed. But when it is guarding a secure link or something, or your Starbucks account, not so much.

Well I just tried to store 50 private keys encrypted in a QR code and it is too much info. This is what lead me to find out what the next big thing is and I came across NFC which looks like a neat idea for the offline transactions.
That could be accomplished with the right programmer in my inexperienced opinion. What decoder are you using?
I found this:
http://stackoverflow.com/questions/6249442/secure-encrypted-qr-codes
They are both neat, but RFID has been around longer and is therefore more vulnerable. If QR codes stay out in front in popularity they will become more vulnerable.

I like this idea for RFID : https://bu.mp/
It is totally based on math and is reliable because of it.

NRC requires a chip, QR codes only require software. Looking even farther into the future is "augmented reality" (AR).
Both NFC and QR codes are crackable. I do not know yet about AR.
