It would be better if modes and routines runs by just scanning an NFC tag's UID instead of writing to it. Also give the option to manually set the UID of the tag to be scanned for.
1. This would make it sharable to other users as they will be able to use the same NFC tag to perform the same routine.
2. This would also work by scanning any Tap to Pay enabled credit/debit card. Helps in automating payments or other actions. An example would be to tap a transit card which opens up an app for recharging the card.
