There are five types of nfc
NFC=Near Field Communication\/ Near Field Communication is a near field wireless communication technology that uses the 13.56MHz band to allow contactless point-to-point data transmission and exchange between electronic devices (within 10cm). This technology evolved from RFID technology, and backward compatible with RFID, was first promoted by Philips, Nokia and Sony, and was originally mainly used for data exchange in mobile phones and handheld devices.
NFC technology integrates the functional design of non-connected Reader \/Reader, non-connected Tag \/Tag and Peer-to-Peer data exchange! The NFC Forum, as the author of the technical specification, defines the following five types of NFC tags.
Type 1: Based on ISO14443A. It has the ability to read and re-write, and the user can configure it as read-only. The storage capacity is 96 bytes, which is used to store URL or other small amounts of data. However, the memory can be expanded to 2k bytes. The communication speed is 106 kbit\/s.
Typical chip class Topaz 512 (BCM20203)
Type 2: Also based on ISO14443A, it has the ability to read and re-write, and the user can configure it as read-only. Its base memory size is 48 bytes, but it can be expanded to 2k bytes. The communication speed is also 106 kbit\/s.
Typical chip types are Mifare Ultralight\/Ultralight C, NTag203\/210\/213\/215\/216, etc.
Type 3: Data communication speed of 212 Kbit\/s. Therefore, such labels are more suitable for more complex applications, and the cost is higher.
Type 4: This type of label is defined as compatible with ISO14443A, B standards. Preconfigured to be readable\/rewritable, or read-only at the time of manufacture. The chip has more memory and communication speeds between 106 kbit\/s and 424 kbit\/s. The typical chip type for a variety of applications is DESFire series, with capacities ranging from 2K,4K,8K.
Type 5: This type of tag is the latest type of NFC tag defined in recent years, and the corresponding RFID protocol is ISO15693 series RFID chips. The NFC Forum introduced this series of chips to meet the growing variety of long-range, miniaturized NFC tags and their applications.
nfc equipment supports models: Huawei p40, mate40 series, oppofindx3, 5 series, and so on, and now most of the flagship models of mobile phones support nfc functions.
NFC stands for Near Field Communication. It is a wireless technology initiated by Philips and jointly promoted by Nokia, SONY and other famous manufacturers. Application NFC devices can be used as contactless smart cards, reader terminals for smart cards, and device-to-device data transmission links.
