Default setting = Slot 1 is sent via NFC

If you haven't made any changes to the NDEF Programming in the Personalization Tool, your Yubico OTP credential in slot 1 is sent over NFC. If you want to send Slot 2 instead, you have to change the NDEF settings using the Personalization Tool (Tools > NDEF Programming).

Please search the forum, this topic has been covered extensively.

One of the links that links to states the following.
Additionally, it doesn't seem to say anything about the NFC support for OTP

http://www.yubico.com/wp-content/upload ... l_v3.4.pdf

3.7.1 The key is inserted and the indicator light does not light up
This probably means that the YubiKey does not have power
● Verify that the YubiKey is properly seated in the USB port
● Verify that the YubiKey is not inserted upside-down.
● If attached to an external hub, check that the hub has power
● Verify that another USB device works in the same port

7.7 Contact-less mode (NFC) of operation
The contact-less (NFC) mode of operation is automatically enabled when the
device is not plugged into the USB port. In NFC mode, the device exposes
an ISO14443A interface, supporting the ISO14443-4 (T=CL) protocol. The
command set is identical to the CCID mode of operation.
The YubiKey button and LED are not enabled in contactless mode.

Doesn't that mean NFC is not supported for the OTP?

Let me get this straight.
Yubico offers no tool to configure the key to behave for NFC OTP?
I have to write custom code to do that?

I find that hard to believe.
Are we missing something here?

Thanks.

Yes. Yubikey is a NDEF Tag Type 4. Here is the link with the info you need:

viewtopic.php?f=26&t=1106

Edit: A doc that clarifies would be the Type 4 tag specification.

[QUESTION] capture OTP via NFC

2016-02-12T19:00:20+01:00

Can the One Time Passcode be captured when resting on the NFC reader?
Or must the neo be inserted in a usb slot?

Is there a doc that clarifies this requirement?

Thanks
