# How to Use NFC on iPhone X The iPhone X marked a significant advancement in Apple's integration of Near Field Communication (NFC) technology. Unlike earlier models, the iPhone X supports **background NFC tag reading**, allowing it to interact with NFC tags without needing a dedicated app open first. This feature, enabled starting with iOS 13, opened up a world of possibilities for automation, information access, and connectivity. ## My Personal Experience with iPhone X NFC I remember when I first got my iPhone X; the NFC capabilities felt like a hidden superpower. Initially, I only used it for Apple Pay, which was incredibly convenient. However, once iOS 13 rolled out, I started experimenting with **automating my daily routines**. I placed an NFC tag on my nightstand that, when tapped with my iPhone X, would trigger a "Good Night" scene—turning off the lights, setting my alarm, and activating Do Not Disturb. This small integration of technology genuinely simplified my life and felt like a personal skill in home automation. ## Technical Specifications and Parameters of iPhone X NFC For developers and tech enthusiasts interested in the hardware specifics, here are the detailed technical parameters of the NFC component in the iPhone X: * **NFC Controller Chip:** NXP Semiconductors PN80T (likely a variant of the PN67V or similar series). The exact internal Apple designation is believed to be part of the A11 Bionic chip's secure enclave subsystem. * **Communication Standard:** NFC Forum compliant; supports ISO/IEEE 18092 (NFC IP-1), ISO/IEEE 14443 Type A (used by most transit and access cards), and FeliCa (common in Japan). * **Operating Mode:** Read/Write mode, Card Emulation mode (for Apple Pay and Express Transit), and Peer-to-Peer mode (though rarely used publicly). * **Frequency:** 13.56 MHz * **Data Transfer Rate:** Up to 424 kbit/s * **Reading Range:** Typically 1-4 cm, optimized for secure, intentional interactions. > **Important Note:** These technical parameters are reference data based on industry teardowns and analysis.
