RFID (Radio-Frequency Identification) and NFC (Near Field Communication) are two wireless communication technologies, both of which are used to identify and exchange data, but differ in some respects. Here is some basic information about the use of RFID and NFC tags:
An RFID tag is a passive device that does not require batteries to operate, and it communicates with the reader through radio frequency signals.
RFID tags can be divided into two categories: active and passive. Active tags have a built-in battery, while passive tags get energy from the reader’s RF signal.
RFID tags are widely used in logistics, inventory management, identity verification, access control, etc. in applications.
NFC tags are a special type of RFID tags that support short-range communication with smartphones or other NFC devices.
Similar to RFID tags, NFC tags also have active and passive types. Most NFC tags are passive, transmitting data by reading the radio frequency signal of the NFC device.
Typical applications of NFC tags include mobile payments, bus cards, access cards, smart posters and advertisements, social media sharing, etc.
Dispensing labels usually refer to labels that are encapsulated by dispensing process. Glue dropping is a common packaging method, which can form a protective layer of glue on the surface of electronic components to prevent the components from being affected by the environment. Epoxy labels have certain advantages in some specific scenarios, such as waterproof, dustproof, and durability.
Therefore, “NFC glue label” may refer to the application of NFC technology to the glue label, so that the surface of the label has NFC communication function and glue protection
The steps used by RFID and NFC tags are usually as follows:
Programming: Before you can use a tag, you need to write relevant data or information into the tag. This process is called programming. Programming can be done during production or dynamically programmed while in use.
Read: Bring a reader or device containing RFID or NFC technology close to the tag. The reader/writer sends a radio frequency signal to the tag, which then returns the data stored inside it.
Process data: The reader transmits the read data to the connected system or application for processing. Depending on the application scenario, different data processing methods may be adopted.
Please note that RFID and NFC technologies operate in different frequency ranges, so you need to ensure that the frequencies between the reader and tag are compatible when using them.
In general, RFID and NFC tags are widely used in modern life and can provide more efficient, convenient and secure data exchange and information management methods.
