An NDEF (NFC Data Exchange Format) tag refers to an NFC (Near Field Communication) tag that is preformatted to store data in accordance with the NDEF standard. NDEF tags are commonly used with NFC-enabled devices, such as smartphones or NFC readers, for exchanging information or triggering specific actions.
1.NDEF标准:NDEF de是一种标准化的格式fined by the NFC Forum for organizing and storing data in NFC tags. It provides a common structure for encoding data and ensures interoperability between NFC-enabled devices.
2. Data Storage: NDEF tags have a specific memory structure that allows them to store NDEF messages and records. An NDEF message can contain one or more NDEF records, and each record holds a specific piece of data or information.
3. Record Types: NDEF tags support different record types that define the content and purpose of the stored data. Common NDEF record types include URI (Uniform Resource Identifier), text, MIME (Multipurpose Internet Mail Extensions) types, smart posters, and more. Each record type has a specific format and usage guidelines.
4. Data Content: NDEF tags can store various types of data, such as URLs, plain text, phone numbers, email addresses, contact information, location coordinates, or application-specific data. The data is stored in a structured format within NDEF records.
5. Read/Write Capability: NDEF tags can be both read from and written to by NFC-enabled devices. This allows data to be read from the tag or updated/modified by writing new data onto the tag. NDEF tags can be reprogrammed multiple times, enabling flexibility in the information stored on the tag.
6. Application Compatibility: NDEF tags are widely compatible with NFC-enabled devices and applications that support the NDEF standard. They can be used in various NFC applications, such as mobile payments, contactless ticketing, smart advertising, device pairing, and information sharing.
7. NFC Tag Types: NDEF tags can be implemented using different types of NFC tags, such as NFC stickers, NFC cards, NFC key fobs, or embedded NFC tags. The choice of tag type depends on factors like form factor, memory capacity, and the specific application requirements.
When working with NDEF tags, NFC-enabled devices can read the data stored on the tag and interpret the NDEF records to trigger specific actions or display the relevant information. NDEF tags provide a standardized and versatile solution for storing and exchanging data using NFC technology.
