Probably easy enough for someone to write when the API is out of beta… it’d only presumably only need read only access. NFC payment is harder but would presumably ‘just work’ once android pay is working.
when I said Samsung Pay etc I meant all NFC payments such as Apple Pay and Android Pay. With the search bar you will find dozens of threads on all three systems if you are interested in reading past comments and responses
Android wear 2.0 does support NFC HCE but I’m more focused on an app to view current and past transaction from an android wear device more. The payment from the device is really not that important with android pay around
