The NFC standard should allow the phone to set any ID by will. However, it only .You can try NFC Tools or the MiFare Classic Tool to emulate cards from your phone, but in my experience it's too limited. NFC tools can emulate tags but I've tried it with hotel keys and it wouldn't work. I'm assuming your work has some sort of encryption. I wanted to emulate my .

NDEF data is encapsulated inside a message (NdefMessage) that contains one . The NDEFReader interface of the NFC API is used to read from and write data to compatible NFC devices, e.g. NFC tags supporting NDEF, when these devices are within the reader's magnetic induction field. NDEF data is encapsulated inside a message (NdefMessage) that contains one or more records (NdefRecord). Each NDEF record must be well-formed according to the specification of the type of record that you want to create.

The NFC API allows exchanging data over NFC via light-weight NFC Data Exchange Format (NDEF) messages. Note: Devices and tags have to be formatted and recorded specifically to support NDEF record format to be used with NFC.NDEF is an abbreviation for NFC Forum Data Exchange Format, a lightweight binary message format that is standardized in [[!NFC-NDEF]]. An NDEF message encapsulates one or more application-defined NDEF records. NDEF messages can be stored on an NFC tag or exchanged between NFC-enabled devices. The NDEF Tools for Android utility project helps doing the following. Detect, then. Read or write, or. Beam (push) NFC content. The project also includes data bindings for all standardized NDEF record types, which really simplifies things compared to working with the (byte-array-based) NDEF classes included in the Android SDK. Also see the NFC .

The write() method of the NDEFReader interface attempts to write an NDEF message to a tag and returns a Promise that either resolves when a message has been written to the tag or rejects if a hardware or permission error is encountered. This method triggers a permission prompt if the "nfc" permission has not been previously granted. When working with NFC tags and Android-powered devices, the main format you use to read and write data on tags is NDEF. When a device scans a tag with NDEF data, Android provides support in parsing the message and delivering it in an NdefMessage when possible.

NDEF Library for Arduino. Read and Write NDEF messages on NFC Tags with Arduino. NFC Data Exchange Format (NDEF) is a common data format that operates across all NFC devices, regardless of the underlying tag or device technology. This code works with the Adafruit NFC Shield, Seeed Studio NFC Shield v2.0 and the Seeed Studio NFC Shield.NFC interactor is a powerful Near Field Communication tag reader / writer app, aimed at enthusiasts and developers. NFC Tag Reading and NDEF Parsing. Tap NFC tags to analyze their real contents. NFC interactor will instantly tell you the writable tag size and parse standardized NDEF messages to human readable form.API docs for the NDEFReader class from the web_nfc library, for the Dart programming language.
