![]() The NFC antenna on the iPhone 11 is located on the top edge. Where is the NFC antenna on the iPhone 11 ? Try and ensure that the hotspot is clearly indicated so the user can position the iPhone 11 correctly to read the tag. Avoid placing too much material and distance between the tag and the user. However, also bear in mind positioning of the tags. Seritag recommend the use of standard 20-40mm tags for the most reliable and consistent performance. Conversely, the use of very large tags (credit card size for example) can result in very poor or failed performance. As a result, many users have commented that scan performance with some of the smaller NFC tags is not great. The iPhone 11 has a relatively small and focused NFC antenna. As with Android, Seritag recommended avoiding the larger memory NTAG216 chips. The iPhone 11 can read all standard NFC chips including the popular NTAG series and iCode SLIX tags.

The iPhone will not normally respond to tags without encoding. Note that your NFC tags need to be encoded with data, such as a web address (URL), before they will scan. Seritag understand that this requirement is not likely to change and 'native' tag scanning will only be available on the XR, XS, XS Max, 11, 11 Pro, 12, 12 Pro and future generations of the iPhone. However, unlike the iPhone 11, the iPhone 7, 8 and X don't have background tag scanning and still require an App to scan NFC tags. Note that the additional functionality added with iOS 13 also applies to previous generations of the iPhone. Essentially, the functionality is now the same with the latest iOS 13 on the iPhone 11 as it is with Android phones. With iOS 13, the iPhone 11 can read the UID of the tags and interact using more advanced methods. ![]() However, with the latest release of iOS 13, Apple changed this and added most of the missing functionality. It also cannot interact with the tag to access other features such as reading the tag scan counter. It cannot read from other memory locations on the tag such as the tag's UID (unique ID). For example, the phone can read the URL/web address stored on an NFC tag. With iOS 11, the iPhone 11's reading ability is limited to just the main memory section of the tag which is commonly referred to as the 'NDEF' memory space.
