Scan Japanese driving licenses with the NFC reader on your device and read more info on them.

Unlock KeePass database with any NFC tags such as: * Mifare Ultralight * Mifare Classic * NTAG203 * Sony SmartTag (few types are R/W) Supports: * Keepass2Android online * Keepass2Android offline * KeePassDroid Security: NFC tag stores only random numbers, and the password is encrypted with those numbers (AES-128 algorithm), stored in protected Android device memory. An attacker would have to scan(copy) your NFC tag and either steal and root your Android device to get your password. If you suspect that your NFC tag has been read, you can use NFC Key again to re-write it with new random values, rendering the previous information useless.

NFC Quick Settings is a simple, open source, utility for quickly checking the device's current NFC status, and enabling or disabling NFC with as few taps as possible. NFC Quick Settings has no user interface of it's own. Instead, once installed, you will see a new "NFC" tile available when customising your Quick Settings menu. See "Add, remove, or move a setting" in Android Help for more information on customising the Quick Settings menu: https://support.google.com/android/answer/9083864?hl=en#customize_settings Once the NFC Quick Settings tile has been added to your Quick Settings menu, the tile will show the current NFC status. Android security limitations do not allow any third-party apps, such as this, to turn NFC on or off directly, so when tapped, the NFC Quick Settings tile will simply open the device's NFC Settings page (if the device has one), where you can enable or disable NFC as desired. NFC Quick Settings also has an advanced mode that allows NFC to be toggled directly from the tile, without having to going the NFC Settings page. But this advanced mode requires special permissions, which can only be granted via the Android Debug Bridge on a desktop computer. You can read more about this mode at https://github.com/pcolby/nfc-quick-settings?tab=readme-ov-file#advanced-mode NFC Quick Settings is freely available under the GPLv3 open source license. The source code is available at https://github.com/pcolby/nfc-quick-settings

NFC Radio is a simple audio player for children and adults that allows you to control your music using NFC tags. Simply place an NFC tag on your phone to play or pause your audio file or music.

This is a simple app to read various tags (NDEF, RFID, FeliCa, ISO 14443, etc). It has been forked from se.anyro.nfc_reader.

NFCGate is an Android application meant to capture, analyze, or modify NFC traffic. It can be used as a researching tool to reverse engineer protocols or assess the security of protocols against traffic modifications. On-device capture: Captures NFC traffic sent and received by other applications running on the device. Relay: Relays NFC traffic between two devices using a server. One device operates as a "reader" reading an NFC tag, the other device emulates an NFC tag using the Host Card Emulation (HCE). Replay: Replays previously captured NFC traffic in either "reader" or "tag" mode. Clone: Clones the initial tag information (e.g. ID). pcapng export of captured NFC traffic, readable by Wireshark.

Proof of concept for a localized message system. It is quite simple, and does the job of reading and writing to any plain text NFC tags. At a minimum you are recommended to use an NTAG216 that gives you approximately 800 bytes of writeable memory. It also has the advantage of being relatively private means of communicating (even if it runs the issue of spoofing), since it is essentially a dead drop system. Potential Uses: * Geo Cache GuestBook * Ingress Local Message Store Features: * Reads Plain Text * Write and prepends a message to a Plain Text Tag * UTF-8 support, so can show emoticon. * Links, email, map address are autolinked

Android home screen widget to display current weather alerts from the US National Weather Service. You can choose a county or state within the US (or the entire US) and it will display a list of all of the current weather alerts for that area on the widget. If there's more than fits, the list scrolls, and you can tap on an alert to open the full text of the alert. There is an accompanying app which can be used to configure what area you want and shows the raw feed data if you're really curious (though that part was mostly there for debugging, and might go away one of these days now that it all works). It does not currently do audible alerts (or any alerts), but that's probably coming soon.
