I am currently looking into building a sports scoring system and i believe i am leaning towards using RFID watch for the input
but my question is can i run 2 Sheilds from 1 device
that way i have 1 watch per user that they could just swipe his wrist near the + or the - and then player b could do the same this is my first venture into this stuff so maybe there is something simpler i could do
