Good evening,

is there a (hopefully simple) way to use NFC on Processing for Android? I was reading from the tutorials that for sensors other than the accelerometer, is suggested to use the Ketai library but i’ve also found that the last release (v14) doesn’t have a working NFC and Ketai it’s not updated since years…  
There is another way to make it work? I don’t need anything fancy, i simply need to make the app read a string on the tag to trigger the display of a page in the app.

Thanks in advance

Ps. I’m a collage student trying to make a simple app and i’m an absolute noob in processing :'D

If you run it in Processing for Android and try to use it with a tag on the phone, they don’t work. It is also said in this topic on the forum that Ketai v14 doesn’t have a working NFC ([NFC on Android?](https://discourse.processing.org/t/nfc-on-android/19126)).
