NFC
A short-range high-frequency wireless communication technology that enables contactless point-to-point data transfer between electronic devices, typically operating at a range of within 4 centimeters.
Timeline (last 90 days)
Proximity sensing is usually based on Bluetooth Low Energy (BLE) beacons or NFC, judging distance by signal strength, with accuracy down to the meter or even centimeter level.
Latch lists NFC as the preferred unlock method because NFC requires the device to be nearly touching the tag, a stronger physical constraint than QR codes and harder to fake with a screenshot or photo.
An NFC sticker is a cheap passive tag (a few yuan each) with no internal power source, drawing power from the electromagnetic field generated when a phone comes close and exchanging a unique identifier.
NFC is a high-frequency subset of RFID, with an operating distance usually within 4 centimeters, commonly found in mobile payments and access cards, and natively supported for reading by most smartphones.
The per-unit cost of RFID/NFC tags can range from a few cents to several dollars, depending on encryption level, storage capacity and packaging form.
Apple Pay is based on NFC near-field communication and device-side tokenization technology, completing payments through credit/debit card networks.
In the US market, regulatory mandates requiring Apple to open the NFC payment interface have not yet been implemented.
NFC is a short-range wireless communication technology with a typical communication distance of within 4 centimeters, and it is the underlying protocol foundation for contactless payments.
Since launching Apple Pay in 2014, Apple has used iOS system policy to restrict the NFC chip's Host Card Emulation capability to Apple Pay use only.
Android's open policy allows third-party applications such as Alipay and WeChat Pay to directly invoke NFC for tap-to-pay.
