NFC tags. Near field communication (NFC) tags are one of the new tools that could potentially replace QR codes. Unlike QR codes, NFC tags do not require an extra application. The NFC chip technology already comes built into the majority of modern smartphones, which is a huge advantage.
Can a QR code hack your phone?
QR codes, as demonstrated, can be used as a vector to compromise your device. The method I explained requires the target to manually download the malicious file, but many other exploits are automatic and stealthy and do not require further actions after scanning the code.
