what can nfc tags do
I've found this : "NFC-compatible tags can be of the following technologies/standards and each of them has a different notion of ID: NFC Tag1 : Topaz/Jewel. NFC Tag2 : Mifare UL (ISO14443A-3) NFC Tag3 : JIS X 6319-4 (FeliCa) NFC Tag4 : ISO14443-4A or ISO14443-4B tag. A UID is a hexadecimal identification number consisting of letters and numbers, 7 bytes in size. The UID is unique worldwide, read-only and can be read by most NFC devices and all NFC-enabled smartphones. The UID cannot be deleted or changed, so that each NFC chip is unmistakably marked.
The NFC chip UID is a manufacturer -supplied, usually read-only, unique identifier for the NFC chip used to uniquely identify an NFC tag in a project’s software systems. The UID is also an important part of NFC security and anti-cloning. In this guide, we will go deep into the world of NFC and explore how to leverage this technology to scan NFC tags in mobile applications using Android and Kotlin. You can read the tag ID of the tag using the following method. fun getUID (intent: Intent ) : String { val myTag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG) return BaseEncoding.base16().encode(myTag.id) }We have two option to read the nfc card. Read from cache. Ndef ndef = Ndef.get(tag); if (ndef == null) {. // NDEF is not supported by this Tag. return null; } NdefMessage ndefMessage = ndef.getCachedNdefMessage(); if (ndefMessage == null) {.
The UID is one of the most important advantages of NFC tags and provides the means to uniquely identify NFC tags and associated objects. Cloning of NFC tags is possible with certain means but should only be considered in security-critical use cases.The NFC chip UID is read by a device from an NFC chip either by reading a specific portion of memory, by calling an NFC chip command or from a software subsystem that performs one of these; which method is used is based on the NFC tag type and NFC chip type.The following are the bare minimum code for creating an Android Application for reading from a NFC tag and writing to it. You will need to know the basics of creating an Android application and you need to have NFC enabled device and a NFC tag. How NFC tags are mapped to MIME types and URIs. Before you begin writing your NFC applications, it is important to understand the different types of NFC tags, how the tag dispatch system parses NFC tags, and the special work that the tag dispatch system does when it detects an NDEF message.
