NFC Devices
NFC devices are used in contactless payment systems, similar to those used in credit cards electronic ticket smartcards and allow mobile payment to replace and supplement these systems. Specifically, combining NFC enabled devices or NFC mobile phones with RFID tags offers additional benefits when compared to traditional RFID solutions. When an application requires that a device have frequent interaction with tags at numerous process points, the high expense of using traditional handheld RFID readers is cost prohibitive. By replacing handheld readers with NFC-enabled phones at data collection points, the ROI for the application increases. HID Trusted Tag® Services is an example of an application that combines HID Global's patented Near Field Communication (NFC) trusted tag technology and cloud-based authentication platform to add unique and trusted identities to everyday objects that can be read by NFC-enabled mobile devices. This is ideal for establishing proof of presence, digital out of home (DOOH) and electronic visitor verification (EVV) and also serves as a real-world application of the Internet of Things (IoT) that has been discussed in Chapter 1. Some of the examples of NFC based mobile devices is discussed in the chapter.
