To scan a passport's NFC chip with a mobile phone, you need an NFC-capable smartphone and a dedicated app such as ReadID or a government-issued identity app [1][2]. The passport must be an e-passport or biometric passport, identifiable by the NFC/RFID symbol on the cover [1]. Before starting, remove any protective cases from your phone and covers from your passport, as these can interfere with the NFC signal [1][3].

The scanning process is two-step. First, use your phone's camera to scan the machine-readable zone (MRZ)—the lines of text at the bottom of the passport's photo page [2][4]. This step is essential because the app uses this data to generate a digital key that unlocks the encrypted chip for security reasons [1][2]. Once the app confirms the MRZ data, it will prompt you to scan the NFC chip itself.

Place your phone flat against the passport and move it slowly until the app detects the chip [1][2]. The NFC antenna location varies by device: on iPhones it is typically near the top or back camera area, while on Android devices it is often near the top or center of the back panel [5][6]. The chip location also varies by passport—commonly in the back cover, photo/data page, or front cover—and the app usually indicates the correct placement [1][3]. Keep the phone still during the scan, which typically takes five to ten seconds [1]. If the connection fails, try removing cases, scanning a different spot on the passport, ensuring the passport is on a flat non-metallic surface, or moving the phone more slowly [1][2][3]. iPhone NFC is generally active by default on supported models, while many Android phones require NFC to be enabled in Settings [7].
