Dear All
I would like to know if there is a way to get the data that the reader provides then a card is in proximity , with out needing to go though the Arduino part of the YUN with an NFC shield
and how can you monitor the USB protocols with in the Yun ?/
Thank you in advance

Dear Sir ,
Thank you for the referral

If you want to use an NFC shield, which plugs into the Yun's shield connectors, and you want to do it from Linux without getting a sketch involved, then you can't do it. If you have any kind of shield connected to the Yun's shield connectors, you need to get the sketch involved - Linux does not have access to the shield connector pins (other than the serial lines on digital pins 0 and 1 which are used for Bridge communications.)
If you want to do it from the Linux side, you need to use a USB reader - to do that, you have sonnyyu's good write-up through the link he provided.
