Radio Frequency recognition technology possesses the benefits of waterproof, anti-magnetic, high-temperature resistance, lange lebensdauer, large reading distance, encrypted data on the tag, large capacity for data capacity storage, and the free exchange of information storage, compared with the barcode.
So definieren Sie den RF-Erkennungsleser?
In den vergangenen Jahren, with the advancement of micro-integrated circuit technology, Radio Frequency recognition technology readers have been advanced. Passive RFID labels do not need batteries. The energy needed to work is obtained from the magnetic field generated by the RF recognition reader but the reading distance is closer. In den vergangenen Tagen, Radio Frequency recognition active tags are large with high power consumption and shorter service life. Jedoch, the use of the latest technology to manufacture active RF recognition tags has not only a long reading distance but also has the strengths of long service life and reliable performance.
So definieren Sie die Tag-Antenne der RF-Erkennung?
The tag antenna of Radio Frequency recognition is the transponder antenna of Radio Frequency Identification electronic tag, which is a kind of communication induction antenna. It is generally combined with the chip to constitute a Radio Frequency Identification electronic tag transponder. Due to the different materials and manufacturing processes, the tag antenna of RFID can be divided into a metal etched antenna, printed antenna, copper-plated antenna and other kinds.
Verschiedene Arten von RFID-Technologie
Radio frequency identification technology can be categorized into three types based on its label power supply approach, namely Passive Radio Frequency identification, active Radio Frequency recognition as well as semi-active RFID.
Passives RFID
Of the three types of Radio Frequency identification items, passive Radio Frequency recognition was developed in the earliest time and it has been more widely applied. In passive Radio Frequency identification, the electronic tags identify the microwave signals transferred by the reader through radio frequency and acquire energy to temporarily power itself through the electromagnetic induction coil so as to complete this information conversion.
As there is no power supply system, the capacity of passive RFID items can reach the centimeter level or even smaller levels, and their own structures are simplified with low price, low failure rate, and longer battery life. Jedoch, as for the shortcomings, passive Radio Frequency identification’s effective recognition distance is generally shorter and generally utilized for close touching recognition. Passive Radio Frequency recognition primarily functions in a lower frequency band of 125KHz, 13.56MKHz, usw. Its common applications cover a bus card, second-generation ID cards, meal cards and so on.
Aktives RFID
Active RFID has emerged in a very short time but has already been applied in various fields, which especially plays an indispensable role in the highway electronic non-stop toll collection system. With the aid of the external power supply, Active RFID initiated sends signals to the RF recognition readers. It possesses a relatively large capacity. Daher, it also owns a long transmitted range and high transmitted speed. Ein klassischer aktiver RF-Erkennungs-Tag ist in der Lage, die Verbindung zum Lesegerät aus einer Entfernung von 100 Metern aufzubauen, und die Leserate kann 1.700 Lesevorgänge pro Sekunde registrieren. Aktives RFID funktioniert hauptsächlich im 900-MHz-Band, 2.45GHz, 5.8GHz und andere höhere Frequenzbänder, und besitzt die Rolle, die in der Lage ist, mehrere Labels gleichzeitig zu bestimmen. Die große Reichweite und die hohe Effizienz der aktiven Radiofrequenzidentifikation machen sie in mehreren RFID-Anwendungsbereichen von entscheidender Bedeutung, in denen eine hohe Leistung und eine große Abdeckung erforderlich sind.
Semiaktives RFID
Die passive Radiofrequenzidentifikation kann zwar nicht selbst Strom liefern, aber der Erkennungsabstand ist für eine effektive Methode zu kurz. Die aktive RFID-Distanz ist groß genug, erfordert jedoch aufgrund des großen Volumens eine externe Stromversorgung. And semi-active RF recognition is the product of making up for this shortcoming. Semi-active Radio Frequency identification is also named low-frequency activation triggering technology. Under common conditions, semi-active RF recognition items are in a dormant status, and only power parts of the tags keep the data so the power consumption is low, and is able to be kept for a long period of time.
When the tag enters the RFID reader recognition range, the reader will first precisely activate the tag to make it enter the working state with a 125KHz low-frequency signal in a small range, and then transfer the information through the 2.4GHz microwave. That is to say, the low-frequency signal will be first utilized to achieve precise positioning, and then the high-frequency signal will be applied to realize fast transmission data. The common application scenario is that several low-frequency readers are put at different positions to activate semi-active RF recognition items in a wide range that can be covered by HF signals. This accomplishes both locating and information collection as well as transmission.
Woraus besteht RFID hauptsächlich??
- – Tag: composed of coupling components and chips. Every tag has a special electronic code, attached to the object to recognize the target.
- – Reader: read (can write as well) tag information devices, can be designed for handheld or the fixed type.
- – Antenna: transmit radio frequency signal between the label and the reader.
The basic working principle of Radio Frequency identification technology is not complicated: Der Tag tritt in ein Magnetfeld ein und empfängt ein Hochfrequenzsignal vom Decoder.
Mit der aus dem Induktionsstrom gewonnenen Energie, Die im Chip gespeicherten Produktinformationen werden versendet (passive Tags, passive Tags oder passive Tags), oder der Tag sendet aktiv das Signal einer bestimmten Frequenz (Aktive Tags, aktive Tags oder aktive Tags). Der Decoder ist in der Lage, die Informationen zu lesen, zu dekodieren und sie dann an das zentrale Informationssystem zu übertragen, um die zugehörigen Daten zu verarbeiten.
Die Stärken und Schwächen des RFID
Die Stärken des elektronischen Radio-RFID-Tags

– Reusability: RFID tags can be added many times, modified, and deleted from the data stored in the Radio Frequency recognition roll tag to boost the information update.
– Miniaturization of volume and shape diversification: When reading the information, RFID will not be restricted in size and shape. Auch, it doesn’t need to read the accuracy of the paper with the fixed size and printing quality. Zusätzlich, RFID tags can be more miniaturized and diverse kinds of development in order to be applied to different products.
– Security: RF recognition stores electrical messages and its data can be protected by a password so that the data is difficult to be forged and tampered.
The drawback of the RFID electronic tag
Although RFID technology has many benefits, there are also some shortcomings that don’t follow the laws of the market in the face of rapid changes in the market. The shortcomings of RFID technology are described below:
- Immature technology: RFID technology has emerged in a relatively short period of time so its technology is not very mature. Due to the retro-reflective characteristics of Ultra High-Frequency RFID tags, it is more difficult to be applied to metals, liquids and other goods.
- High cost: compared to ordinary bar code tags, RFID electronic tags are more expensive, which is dozens of much costs than ordinary bar code tags. If it is utilized in large quantities, the cost will be too high, and to a large extent, greatly decrease the market enthusiasm for the use of RFID technology.
- Weak Security: RFID technology faces several security problems, which are mainly manifested in areas like the RFID electronic tag information is illegally read and malicious tampering.
- Non-uniformed technical standards: RFID technology has not yet formed a unified standard, and a variety of standards on the market coexist, resulting in the incompatibility of different enterprise products RFID tags, which in turn, in einem gewissen Ausmaß, causes chaos in the application of RFID technology.
- Although RFID technology faces a lot of issues, the success of RFID is in line with the market development in the modern market development law so whether the future applications of RFID technology can be better developed is mainly based on the market demand.
RFID vs. NFC
Near Field Communication technology originated from RFID but there are some differences between the two, which mainly include the following.
- Arbeitsfrequenz: NFC operates at 13.56MHz while RFID can be operated at low frequency, Hochfrequenz (13.56MHz) und Ultrahochfrequenz.
- Working distance: Theoretisch gesehen, the operating range of NFC ranges from 0 to 20cm. Jedoch, in terms of the implementation of the products, the working distance is only 0 to10cm due to the special power suppression technology, thus better ensuring the security of the business. As RFID has differed frequencies, its worked distance varies from several centimeters to tens of meters.
- Working model: NFC supports both the read-write model and the card model. As for RFID, the reader and the contactless card are two separate entities that cannot be switched from each other.
- Peer-to-peer communication: NFC supports P2P mode while RFID doesn’t s.
- Application areas: RFID is more often applied in manufacturing, Transport, tracing and asset organization while NFC works in access control, bus card, cell phone payments and other areas.
- Standard protocols: The basic communication protocol of Near Field Communication is compatible with the basic communication standard of HF Radio Frequency recognition, d.h., it is compatible with ISO14443 or ISO15693. Near Field Communication technology also gives definition to more complete upper layer protocols including LLCP, NDEF and RTD. Um zusammenzufassen, despite the differences between NFC and RFID technologies, NFC-Technologie, especially the basic communication technology, is fully compatible with high-frequency RFID technology. daher, NFC-Technologie can also be utilized in the area of high frequency RFID.
