FAQ: NFC Burner applications
Find the answers to frequently asked questions about our burner applications below. 
Please have a look at this article, explaining the NFC stability issues. 
Token2 Burner App for miniOTP-1 is using the following error codes:
0x10040011 or 0x10030011-  means NFC connectivity is unstable or cannot be established. Before burning please make sure your phone sees the card by using “get OTP” button.


If NFC is still not working try changing the position of the token to make sure antennas overlap - i.e. from vertical to horizontal or vice versa. The exact location of the NFC antenna depends on the phone model, but usually it is under the camera (see the illustration of Samsug Galaxy S6 as an example).
 


The NFC antenna on the phone should ideally overlap with the NFC chip of the programmable token covering as larger surface of the NFC antenna as possible. The image below shows the location of the NFC chip of miniOTP-1 card.
 0x10050012 - is shown if the seed length is higher than the maximum allowed (40 chars in hex , 32 chars in base32 format)
