I'm now searching your system for contactless devices
** found usb:054c:06c3 at usb:001:004 but access is denied
-- the device is owned by 'root' but you are 'pi'
-- also members of the 'root' group would be permitted
-- you could use 'sudo' but this is not recommended
-- better assign the device to the 'plugdev' group
   sudo sh -c 'echo SUBSYSTEM==\"usb\", ACTION==\"add\", ATTRS{idVendor}==\"054c\", ATTRS{idProduct}==\"06c3\", GROUP=\"plugdev\" >> /etc/udev/rules.d/nfcdev.rules'
   sudo udevadm control -R # then re-attach device
I'm not trying serial devices because you haven't told me
-- add the option '--search-tty' to have me looking
-- but beware that this may break other serial devs
Sorry, but I couldn't find any contactless device
