is nfc dangerous 
there is no evidence to suggest that nfc technology is harmful to your health nfc or near field communication is a type of wireless technology that allows devices to exchange data over short distances it operates at a frequency of 13 56 mhz which is considered to be a low power frequency while some studies have shown that long term exposure to certain types of radio frequency rf radiation can have negative health effects the level of rf radiation emitted by nfc technology is so low that it is not considered to be harmful can you be hacked through nfc it is possible for an attacker to hack into a device using nfc technology although the likelihood of this happening these days is relatively low nfc operates over very short distances typically less than four inches so an attacker would need to be in close proximity to the device in order to access it additionally most nfc enabled devices are configured to only establish a connection when the user specifically allows it so an attacker would need to trick the user into initiating the connection however even if an attacker is able to establish an nfc connection with a device they would still need to find a way to exploit a vulnerability in the device s software in order to gain access this is not necessarily an easy task and the level of difficulty would depend on the specific device and its security measures in general it is always a good idea to keep your device up to date with the latest security patches and to be cautious when connecting to unfamiliar devices using nfc the bottom linenfc or near field communication is a type of wireless technology that allows devices to exchange data over short distances it is commonly used for contactless payment systems such as mobile payment apps like apple pay as well as for access control systems like keyless entry to buildings or hotel rooms nfc technology is also often used in marketing allowing businesses to provide customers with information or offers through their nfc enabled smartphones the technology operates at a low power frequency and is not considered to be harmful to human health when using a smartphone or tablet nfc is as safe as any other wireless technology such as wifi or bluetooth however enabling nfc can drain your battery and skillful hackers may be able to hack your device or digital pickpocket you from close range as a result it is often smart to keep the nfc feature turned off while it is not needed
