I got sent a link today talking about how the business card company "Moo" is implementing a chip into their cards that will allow NFC connections to do many things such as share contact info, open a website, open a social media page, etc etc.
So I personally don't know a ton about NFC or the connection it establishes, but to my knowledge all it is, is a radio connection. So once the chip and device realize they are connected it runs a command, probably something like
if device=connected{
do this
} else {
end / don't run command
};
I was wondering, just how secure can this connection be? Just off the top of my head I feel like it poses a major security risk to a couple threats, just a list I thought of:
You tap the card and:
- The chip installs software (keylogger)
- The chip steals something (Apple keeps your payment info in general settings of the app store)
- The radio signal is intercepted by a third party
How possible are these scenarios? Should anyone be concerned with using the new NFC cards?
(Sorry not really sure what to tag this)
