Hello, I'm in need of a simple mobile application for both iOS and Android (probably using React Native or Flutter if possible, but I'm open). We sell two products, a Sleeve and Bracelet which allows the owner to use NFC from their phone to add a link to their bracelet which can be shared to other people. The Android version is already built and on the Google Play store BUT it was built by an old developer that we cannot get in contact with, so we don't have the source code. The app can be found under the name "The SmartSleeve Tag and Tap Mobile App" on the Play Store. They just need this same exact app rebuilt for both Android and iOS (with a couple wording changes). The entire app is only a couple screens and I can provide documentation from the previous developer regarding the NFC specification. See specification details below: The NFC chip being used is an NTAG21x (x can be 3,5,or 6, we've been using NTAG216 since it has the most memory). Only the NTAG21x chips have this password feature. The datasheet for it (which has a summary of the commands and responses) is here: [login to view URL] I've attached the documentation for the NTAG PWD functionality provided by the previous developer.
