Description

From the listing uploaded by “appupdater”.

Re-use/ recycle write protected NFC Tags such as hotel key-cards, access badges, price tags, lift cards, key fobs etc... You can use this app to associate multiple functions (e.g. Wlan OFF, Bluetooth ON, Mobile Data TOGGLE, start navigation,run Tasker task, start any installed app, use media buttons, call a phone number, add a timestamp, calendar entry, add Text-to-Speech and much more!) to a NFC (near field communication) tag via an app internal database. You can even add tag cycles and let your tag run different activities per scan. So ReTag is the perfect NFC automation tool for you ;-). (Works with ANY android supported tag = re-writable AND write protected!) With NFC ReTag you don´t have to write anything on the tag (-> uses the tag ID, great for small tagsizes and write-protected tags!) and NO data is send to the internet. Additional write options (for better dispatching, device independent tags etc.) are also available. Import of activity tags and beaming is also supportet. *!* NFC enabled device required / NO root required *!* Support forum: http://forum.xda-developers.com/showthread.php?t=1477138 If you have any issues, please do not hesitate to write us an e-mail. You could combine any activities/ actions and add as many activities and cycles as you want per tag. (obviously except for writing activity tags -> depends on tagsize). For best performance and dispatching, write a special NFC ReTag tag (this is NOT an activity tag!). Available activities: Device Settings * Set Ringer (silent/ vibrate/ normal) * Set Ringer Volume * Set Music Volume * Set ALarm Volume * Set Brightness (auto/ value) * Set Auto Sync (on/off/toggle) * Set Auto Rotate (on/off/toggle) * Set Display timeout * Set Stay On while Loading (AC/USB/AC+USB/Never) Wireless & Networks * Set Wlan (on/off/toggle) * Set Bluetooth (on/off/toggle) * Set Airplane mode (on/off/toggle) * Connect Wifi Hotspot (on/off/toggle) * Connect Wifi SSID (SSID) * Set Mobile Data (on/off/toggle) Start & Launch * App/ Activity Launcher (any app on your device) * Music (Toogle Play, Stop, Next etc.) * Navigation (adress) * Website (URL) * Tasker task * Carmode (on/off/toggle) Phone/ Message * Dial(number) * Call (number) Calendar & Alarm * Set Alarm (07:32) * Set Alarmtimer (in 12 min) * Add Calendar entry * Make Timestamp Misc & Labs * Say something (TextoSpeech) * Start Secret code * Go to Homescreen * Show Pop-up (Text) * WAIT (milliseconds) * Add new SSID (great for sharing/ beaming WiFi SSID and password) * Say current time * Launch App Activities * Bluetooth discoverability * Set default ringtone, notification tone, alarm tone * GPS * Tasker Task advanced * ReTag Broadcast (for 3rd party apps) Addition Features: * Unique tag cycles (activities for scan 1, scan 2, scan 3 etc.) * Write/import NFC ReTag activity tags * Beam your activity cycles * Write special NFC ReTag tag (better dispatching) * Write Smarttags (Green, Blue etc.) * Backup/ import database * Disable NFC ReTag background dispatching * Save tag as template * Support for placeholders (e.g. [%UID], [%DAT]) * BT and WiFi trigger * and many many more ... Full description and changelog: http://forum.xda-developers.com/showthread.php?t=1477138 An ad supported free version (with limited number of tags) and an unlimited ad-free (PRO) version is available. Please check if this app works on your phone via the FREE version before downloading the PRO version. Supports any standard android NFC tags (NFC Forum Type 1, Type 2, Type 3, Type 4 etc.). Hints: Issues with TASKER: Install Tasker BEFORE NFC ReTAG, enable Misc / Allow External Access in Tasker UI, enable Tasker (on/off button), try the Tasker fallback option within NFC ReTag settings! Some security related NFC Tags (e.g. in passports) change their ID on every read attempt. This app will not work with such tags.
