The NFC Forum today approved the Signature Record Type Definition (RTD) 2.0 technical specification, which will help authenticate the data stored on NFC tags. According to the NFC Forum, Signature RTD 2.0 lets developers verify the integrity of data within NFC Data Exchange Format messages, which is the core of how NFC tags and devices communicate with one another. The NFC Forum says the spec can assure companies that the data they're placing in NFC tags is protected from potential hackers. It also lets device owners know they won't be risking anything by reading the tag with their phone. The complete Signature RTD 2.0 specification is available for download from the NFC Forum's web site. NFC has become more critical in recent years with the launch of mobile payment services like Google Wallet, Apple Pay, and soon Samsung Pay. The extra layer of security helps protect the ecosystem from abuse.
