![]() ![]() Seritag have put together some information on how much memory you will need in your NFC Tag. NFC Tags have a very limited memory so getting a tag that will store everything you need is important. How much memory do I need ?ĭepending on what information you need to store on your NFC tags, you will have different memory requirements. We suggest using the NFC Tools app with these chips for encoding or ask Seritag to encode something onto the tags without locking. Note for iPhone users: The ICODE SLIX and ICODE SLIX2 tags need to have already been encoded (have NDEF data) before some iPhone Apps will be able to encode them. As phone specifications can change without notice and also vary from region to region, we strongly advise testing tags before any purchase. The table below illustrates the available NFC tags and their compatibility with your phone. iPhone iPhone XS NFC Hotspot NFC Tags For The Apple iPhone XS The NFC antenna on the iPhone XS is located on the top edge. Where is the NFC antenna on the iPhone XS ? Try and ensure that the hotspot is clearly indicated so the user can position the iPhone XS 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 XS has a relatively small and focused NFC antenna. As with Android, Seritag recommended avoiding the larger memory NTAG216 chips. The iPhone XS can read all standard NFC chips including the popular NTAG series and iCode SLIX tags. Which NFC tags can be used with the Apple iPhone XS ? You can also watch our 90 second encoding NFC tags with an iPhone tutorial on youtube. Seritag have put together a quick step by step tutorial on encoding NFC tags with an iPhone. Prior to iOS 13, the iPhone XS could only read NFC tags. With iOS 13, Apple have added the functionality required to both encode and lock NFC tags. Yes, providing the latest iOS 13 is installed. Can the iPhone XS write/encode NFC tags ? Not sure what an NFC tag is ? Read our article on What is an NFC Tag. 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 iPhone XS and future generations of the iPhone. However, unlike the iPhone XS, 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 XS as it is with Android phones. With iOS 13, the iPhone XS can now 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 XS's reading ability is limited to just the main memory section of the tag which is commonly referred to as the 'NDEF' memory space. Val callback = : NfcAdapter.To find out how to scan tags, read our tutorial on how to read NFC tags with an iPhone. Private var nfcAdapter: NfcAdapter? = null Private lateinit var binding: ActivityMainBinding Make sure the NFC reader is activated on your mobiledevice. Make sure the mobile device settings arecorrect. Here is the code for my MainActivity: package If you are unable to read the NFC tag on your mobiledevice, try the following solutions (PowerLite1781W/1785W/1795F): Make surethe mobile device is unlocked and not in standby or sleepmode. I am using Kotlin and have followed the code example provided on the Android Developer website, but my app is not able to read any NFC tags. Am trying to build an Android app that can read the contents of NFC tags. ![]()
