NFC seems to be quite welcome to many people, even those who usually were rather holding back and cautious.
Maybe this could be a topic worth for discussing.
I am not really a friend of NFC as I think again it also lacks security and customers rather loose control of it.
My focus is on using it for payment which seems to be the key feature for this “near field communication” technique.
Different banks keep their own regulation on the amount limit that may be transferred per use until the pin is required. Some banks allow to disable the NFC function or set an individual max. amount.
Although I am quite satisfied with my bank DKB it neither allows me to disable the functionality nor to change the limit fixed at 25.-€.
Once being used, it’s enabled and cannot be undone.
Loosing control as a customer, well it wasn’t me who enabled it, but the customer friendly staff at the cash register of my favored tailor. So now many shops simply take it and use this function to their convenience. I just can look and see quick as it goes.
The problem I see here: If staying below the limit, mine is fixed at 25.-€, but many report having 50.-€ by default. So making several purchases within this limit may also get someone into depths as no pin is required. Let’s assume someone finds such a card purchasing several items up to 25/50 €, that’s all it takes. At the end of a day the owner may face a debit of 250/500€ or even more.
It would be a lot more secure for the owner if by random each 5-10 times (per hour maybe) the NFC function is used, entering the correct pin is mandatory locking the card otherwise just as when in conventional use.
Up to now I did not hear of such a mechanism being implemented or another security step limiting this function when the card is in the wrong hands.
