I previously had an original Galaxy Watch. I used the NFC ability on the watch to allow me to get through the doors at work as all main entries and lift use is done via NFC cards, I just added my watch.
Yesterday I got myself a Galaxy Watch 4 but I'm having a problem with the door system at work.
Every time the watch is placed near a reader, a different number is given whereas the old galaxy watch would give the same number everytime.
As the number changes every time it's read, it can't be added to the system. Is there a way of stopping this number from changing?
