NFCLabels and contactless methodsICThe difference between cards

NFCTags are a short-range, high-frequency wireless communication technology that allows contactless point-to-point data transmission (within ten centimeters) to exchange data between electronic devices. This technology is powered by contactless RFID (RFID) and is backward compatibleRFID, originally byPhilips、NokiaAndSonyMainly recommended, mainly used in handheld devices such as mobile phones. Because near-field communication is naturally secure,NFCThe technology is considered to have great application prospects in fields such as mobile payments.　

 

NFC Contactless card readers, contactless cards, and point-to-point (Peer-to-Peer) integrates functions into a single chip, opening countless new opportunities for consumers' lifestyles. This is an open interface platform that enables fast and proactive configuration of wireless networks, and also serves as a virtual connector for existing cellular networks, Bluetooth, and wireless 802.11 Equipment.

It is a new technology developed in recent years worldwide, successfully integrating radio frequency identification technology andICBy combining card technology, the problem of passive (no power supply in the card) and contactless operation has been resolved, marking a major breakthrough in the field of electronic devices. Cards within a certain distance range(Usually5—10mm)Close to the reader's surface, data read/write operations are completed through radio wave transmission.

AlthoughNFCLabels and contactless methodsICCards are also operated by "swiping," but in essence, there are significant differences between the two.

UsageNFCLabels have the following benefits

1: Price

In view of thisNFCThe target application of labels is extremely low-cost (for example, for smart posters), and unit price is an extremely important factor in label design. Here, cost is crucial. Label costs are influenced by a range of factors, including memory size and the complexity of integrated circuits resulting from additional features. By simplifying memory and features as much as possible, costs can be reduced.

2: Speed

Because it needs to be in twoNFCAll data contained in the tag is transmitted when the device approaches, so speed is very important. If data transmission on a label is slow, there is a risk of incomplete transmission and poor reliability. As a result, users are affected; those who do not understand the technology lose confidence if they have to repeat it multiple times to succeed. Category OneNFCLabels allow all data blocks (block) transmission, maintaining the tag's reading performance.

3:Dimensions

In label design, wafer size is of particular importance. Smaller sizes mean lower costs and less conspicuous labels. Smaller memory naturally results in smaller chip sizes.
