Can All Mobile Phones Read an RFID Tag?
Are there some models that still do not have that capability? And if so, when will all phones be thus equipped?
Not all phones can read a radio frequency identification tag. The handset must have a built-in Near Field Communication (NFC) device for this to be possible.
NFC, a high-frequency (HF) RFID technology developed by Nokia, Philips (now NXP Semiconductors) and Sony, incorporated existing standards, including ISO 14443, into a single protocol, and also added some other unique features, such as the ability for a reader to emulate a tag.
That enables a person to download, for example, a movie ticket or a bus ticket to his or her phone, and to then swipe that phone by an NFC-enabled turnstile. A growing number of phones are currently being equipped with NFC readers, but it will be several years before all models have that capability.
