Near Field Communication

Near Field Communication (NFC) enables devices within very close proximity—within a few centimeters—to wirelessly exchange information. iOS apps running on supported devices can use NFC scanning to read data from electronic tags attached to real-world objects. For example, a user could scan a toy to connect it with a video game, a shopper could scan an in-store sign to access coupons, or a retail employee could scan products to track inventory. An app can enable single- or multiple-object scanning, and the system brings up a scanning sheet whenever the user is expected to scan something.

Don't encourage people to make contact with physical objects. To scan a tag, an iOS device must simply be within close proximity of the tag. It doesn't need to actually touch the tag. Use terms like "scan" and "hold near" instead of "tap" and "touch" when asking people to scan objects.

Use approachable terminology. Near Field Communication is a concept that may be unfamiliar to some people. To help make it approachable, avoid referring to technical, developer-oriented terms like NFC, Core NFC, Near Field Communication, and tag. Instead, use friendly, conversational terms that most people will understand.

Use Don't use
Scan the [object name]. Scan the NFC tag.
Hold your iPhone near the [object name] to learn more about it. To use NFC scanning, tap your phone to the [object].

Provide succinct instructional text for the scanning sheet. Provide a complete sentence, in sentence case, with ending punctuation. Identify the object to scan, and revise the text appropriately for subsequent scans. Keep the text short to avoid truncation.

First scan Subsequent scans
Hold your iPhone near the [object name] to learn more about it. Now hold your iPhone near another [object name].
