yeah I got it after diving deeper into forum, so I backed 2016 one (cause old one isn`t working anymore (look like NFC tag is fried)) and I will be eagearly wating for payment-able one

there is new campagin on Kickstarter - for KERV (contactless payment ring)
it is possible to integrate such a feature to 2016 NFC ring?

EDIT - so I read through your KS page, according to statement it will be possible, but there will be need of new NFC inlay or it will be possible with 2016 version?
