Explanation and Practical Application of NFC and RFID

In our daily life, there are many uses of NFC and RFID products, such as our mobile phone's NFC function, fast order purchase, through the gate, links to use equipment, RFID products are more manifested in access cards, bank cards, clothing labels, asset management, unmanned supermarkets, payment, and so on. Today, asiarfid will explain the application of NFC and RFID for you.

THE PRACTICAL APPLICATION OF NFC PRODUCTS:

The devices with built-in NFC functions are mainly mobile phones, and many tablets and Bluetooth audio devices have built-in NFC functions. There are five main types of applications of NFC technology on mobile phones:

1. Touch and Go (Touch and Go), such as access control, ticket and ticket management, users can store ticket or gate-controlled password devices close to card reader, and can also be used for logistics management.

2. Contact payment (Touch and Pay), such as non-contact mobile payment, allows users to close devices to POS machines embedded with NFC modules to make payments and confirm transactions.

3. Touch and Connect, such as connecting two NFC devices to carry out Peer-to-Peer data transmission, such as downloading music, image exchange and switching address books.

4. Touch and Explore. Users can browse traffic information by connecting NFC phones to smart public phones or posters with NFC functions on the street.

5. Load and Touch, users can receive or download information through GPRS network for payment or access control functions. As mentioned above, users can send specific formats of text messages to the housekeeper's mobile phone to control the housekeeper's access to the residence.

THE PRACTICAL APPLICATION OF RFID PRODUCTS:

There are three main types of applications of RFID technology: passive RFID products, active RFID products and semi-active RFID products.

1. Passive RFID products are the earliest, most mature and most widely used products in the market. For example, bus cards, canteen cards, bank cards, Hotel access cards, second-generation ID cards and so on, which can be seen everywhere in our daily life, belongs to the close contact identification category.

2. Active RFID products, whose long-distance automatic identification characteristics determine their huge application space and market potential. In the field of remote automatic identification, such as intelligent prison, intelligent hospital, intelligent parking lot, intelligent transportation, intelligent city, intelligent earth and Internet of Things, there are important applications. Active RFID is emerging in this field and belongs to the category of remote automatic identification.

3. Semi-active RFID products, combined with the advantages of active RFID products and passive RFID products, make microwave 2.45G play an advantage under the trigger of LF 125KHZ RFID tag frequency. Semi-active RFID technology, also known as low-frequency activation trigger technology, uses low-frequency close-range accurate positioning, microwave remote identification and uploading data to solve the functions that can not be achieved by pure active and passive RFID.

Simply put, they are short-range activation positioning, long-range identification and uploading data. This product combines the advantages of active and passive RFID. It has great advantages in access control management, accurate positioning of personnel, regional positioning management, perimeter management, electronic fence and security alarm.

What are the differences between active and passive RFID tags?

Passive RFID tags have no power supply; they are activated by the electromagnetic wave emitted by the reader and then send the information back to the RFID reader. The practical range of passive RFID tags is about 10 cm to several meters.

Active RFID tags have a built-in power supply and a microprocessor for special tasks. The data transmission range of active RFID tags is much farther than that of passive tags; an active RFID reader can monitor all active tags within 100 meters.

What are the advantages of passive RFID tags?

If passive asset labeling technology is used, it can read four times faster than using barcode. Users only need to carry a passive RFID reader, even if the tag is not in the line of sight can be detected. Users still need to inspect the actual location of each labeled asset, and the data collection process will run automatically with a low error rate. Asiarifd.com sells various types of RFID tags.

What are the advantages of active RFID tags?

When an object is managed by an active RFID tag, the routine inventory of the object is almost unnecessary. Active RFID tracking scheme will automatically and real-time start asset inventory according to applicability, business and security requirements.

Readers can be permanently installed in key locations (e.g., offices, storage rooms, high traffic areas, exit corridors, etc.) to report on the current status of marked assets in designated areas.

Under what circumstances are these two RFID tags used?

Passive RFID tags are commonly used in retail supply chains to improve inventory tracking and management effectiveness. Passive RFID can be regarded as a kind of "enhanced barcode". (The longer the time used, the worse the quality of printed barcode will be, such as stain and tear, and the reader and barcode are required to be within the scope of vision.) The absence of built-in power means that individuals with passive labels can be fairly small and inexpensive; passive labels for commercial purposes can be nested on sticker labels for use. The bank card, bus card and access card used in our daily life are nested RFID tag cards, also known as IC cards.

Active RFID systems use "lighthouse" tags to regularly relay their status. These tags are transmitted in real time and the tagged assets are identified immediately and continuously. If real-time tracking is needed in a large range, the active RFID scheme is obviously superior to other passive solutions. Active technology has significant advantages in the management of important assets, IT equipment, valuables, mobile and shared resources.

The difference between IC card and magnetic card

In our daily life, we use many kinds of cards, such as bus cards, bank cards, access cards, identity cards, etc., very many. At first, most of the cards used magnetic cards, because magnetic cards are easy to wear and interfere and lead to failure, so now many cards are used IC cards, then what is the difference between IC cards and magnetic cards?

IN APPEARANCE:

Magnetic Card: The core part of the magnetic card is the magnetic strip pasted on the card. The typical magnetic card is the bank card which was first used. The asiarfid.com can customize the magnetic card bank card and so on. There is no difference from ordinary cards, but there is a silver or black magnetic stripe on the appearance. Most of the size and shape are standard cards.

IC card: IC card is also called smart card, integrated circuit card. It encapsulates the integrated circuit RFID tag, or the NFC chip, onto the copper chip, and then embedded into the standard plastic card. The common one is our social insurance card. Most of the cards are white in appearance. The cards can be customized in appearance and size and shape. Asiarfid.com can customize various IC cards, non-standard cards.

ON STORAGE:

IC cards can store more than magnetic cards. The maximum storage of magnetic cards is hundreds of bytes, while the storage of IC cards is calculated according to M. IC card has RAM, ROM, EEPROM and other memory, can store text, sound, image and other information, but also can be segmented, different access levels and so on.

IN TERMS OF SECURITY:

IC card can be encrypted, magnetic card can not be encrypted, because the magnetic card is mainly the magnetic strip on the card, so it can not read and write data, while IC card is an integrated circuit chip card, so it can read and write internal data, control, encryption and so on, so IC card is more secure than magnetic card.

OTHER ASPECTS:

IC cards use integrated circuits with strong performance, high data security, long life of more than 10 years, low dependence on the network, can be used offline, magnetic card life is generally not offline; life is generally 1-5 years, low anti-interference, easy to be forged, are conducive to carrying, using.
