Yep these days most cards use additional authentication whenever used online. Be it enter a SMS code, approve the transfer trough the banks website, approve it via the banks phone app etc... Making it much more difficult to pull off something like this. I still have a separate prepaid debit card for online stuff, so they can only steal how much is on that card. |

When cars were made more difficult to steal, car-jackings increased instead... criminals will be criminals, they just go for the lowest hanging fruit? |
| BrokenYugo:
I'd find mine more useful if it didn't autorun the transaction as debit and force me to manually punch in a pin number anyways. |

So yeah. NFC is convenient, and reasonably secure. It only works reliably at very short distances, despite some lab experiments claiming to have shown communication with NFC devices at several meters - it's either bullshit or requires very expensive equipment. Contrary to RFID in general, NFC is tuned for very short distances. Now there's still the possibilty of losing your card and anyone can use it for NFC payments - but as some have said, it's limited to a relatively low amount per day. Of course, it could still be pretty annoying if you're broke. But these days you can declare the loss of a card very quickly (as long as you are aware of it...) and it'll get blocked. All in all, it's a relatively convenient feature with not that many downsides. What I personally find more concerning is the way it's linked to a completely cashless society, which is a big can of worms, and the topic largely beyond this thread. |
