To see the risk of exposure , rent ’s practice credit cards . Norse banks are often relatively early in adopting jeopardy - basedapproaches such as multi - factor certification and more – and they have also consume a position when it come to bank identity card and NFC .
“ NFC minutes are considered secure enough for a limited , pre - defined amount , of transaction between prolonged validations , meaning they will refuse an NFC - basedtransfer every now and then , and re - enable this only if a transaction using visiting card and PIN number is made . They also only accept NFC - base transactions up to a give amount before call for extended validation with PIN . This is due to the fact that the bank havedetermined the red ink to fraud and attacks satisfactory in this balanced trade wind - off , i.e. the technology is not perfectly safe , but it is good enough to be used in a balanced personal manner .
