For some reason, we did not anounce the new NFC-enabled Yubico NEO on the forum as we launched it publicly. Given the amount of interest and feedback we've got, it seems appropriate to remedy this by telling a bit about it now.
First of all - read our product page at
http://www.yubico.com/yubikey-neoDifferent from the RFID Yubikey, which comprises two separate security chips, the Yubico NEO is an integrated solution that provides Yubico OTPs over an NFC interface synchronous to the OTPs being generated when the Yubikey is inserted in the USB port. This means that the same Yubikey can be used for accessing the same service, both from a desktop setting as well as a mobile setting.
The Yubikey NEO emulates a NDEF type 2 tag, i.e. a NFC interogator which scans it think it is a "smart poster". Although a "smart poster" conceptually describes something that emits a static piece of information (typically an URL with a promotion code or similar), the NEO in the same setting emits a URL + OTP string. This gives a nice out-of-the-box experience when scanning it with an unconfigured NFC phone. The NEO supports the URI and Text NDEF record types.
The NEO works as an ordinary USB-connected Yubikey as well. In the first version it supports one configuration only.
We've uploaded an updated version of the Windows configuration tool that supports writing a NDEF descriptor to the NEO. This version is compatible will all previous versions of Yubikeys.
Anyone who's interested in exploiting application develiopment in Android could use the standard NFC APIs. We've made a proof-of-concept together with Lastpass that shows how a richer user experience can be acheived by installing an app in the phone.
The Yubikey NEO is a different technical platform that the Yubikey 2 / RFID Yubikey. Quite a few additional features are required to acheive this integrated functionality and it should therefore not be assumed that Moore's law automatically will make the NEO the mainstream product. With this said, one should assume that the NEO will have a price premium over the standard Yubikey.
The NEO is now launched in a pre-production version where we're exploring various functionalities together with partners. We expect the NEO to enter full production during H2'2012. We're of course very interested to get your feeback regarding the "final" functionality.
Best regards,
