So……. I’ve recently rediscovered NFC tags for iPhone and you can programme them etc from your iPhone as well as reading them. So far these seem amazing.
However how safe are they? I’ve read online that you can do stuff like read other NFC tags with your iPhone and export the data to a new NFC.
I’ve also read on some websites you can use NFC tags to make purchases for you as a contactless payment. (Obviously I’m not going to try this)
I know there are features such as lock an NFC tag (to stop it being reprogrammed) and you can even password protect tags.
But what about things like hotel keys? Can these theoretically be used to clone hotel keycards too? I’m not sure if the password is to stop you writing to the tag or you need a password to view the tag. So I imagine these sort of tags for doors etc would have some kind of security feature on to prevent this?
It seems apple could have potentially opened up a whole can of worms if this happens.
