In recent years, with the popularization and application of RFID labels. It drives the flourishing of different industries around the world. Wal-Mart, SAP, BEA, Intel, and other prominent international organizations bear the brunt. They are a solid strength to prove the considerable development space of RFID and a wide range of application prospects. So are you using RFID labels now? How much do you know about it? For RFID labels, this article will describe the composition of RFID labels in detail.

What are RFID Labels?

RFID labels can be attached to any part of an object and used to track equipment, inventory, or other objects. It uses contactless automatic identification technology (RFID) to get data on the target object. It is small, versatile, and straightforward to use. It can track animals, mass-produced items in factories, and goods in transit.

Compared to regular barcodes, it is much better. It is waterproof, anti-magnetic, heat resistant, and has a longer life span and more memory capacity. It can read data for single or many items, unlike bar codes that can only identify one type of item and need to be read one by one. The company can place it inside the item, and the reader reads the item through the outer material. In contrast, a bar code must rely on a laser or infrared ray to read the data on the external material surface of the item.

It will vary depending on the power supply method. It can be divided into active, passive, and semi passive labels.

The use of transmitting frequency can be low frequency (LF RFID), high frequency (HF RFID), ultra-high frequency (UHF RFID), and microwave (MW RFID). These are four kinds.

According to different packaging forms, its style will also be different. It can be credit card labels, linear labels, paper labels, and other special-purpose-shaped labels.

On June 13, 2022, Market Research Future (MRFR) published a new comprehensive research report. The report states that the growing adoption of RFID in the healthcare industry has contributed to the growth of the RFID tags market. The report forecasts that the RFID market will reach USD 7,982.2 million by 2027. The market is expected to grow at a CAGR of 13.67% throughout 2020-2027.

What are The Parts Of RFID Labels?

RFID labels are also named RFID tags (RFID smart labels). It has three components: a microchip (IC), an antenna, and a substrate. RFID chips mainly store and process information and modulate. It can demodulate radio frequency signals. The antenna enables the RFID label to receive and send signals from the reader.

RFID Tag Chip

An RFID tag chip can also be called a microchip (IC) or electronic circuit. It is designed and manufactured by a semiconductor manufacturer. It also controls the frequency of the radio waves emitted. It usually has a relatively large memory in its body and can receive signals from other devices on the same channel at the same time. It can read tag information by using RFID readers. It can write new information internally to enable different functional transformations.

IC usually requires power to operate. In the case of an active tag, its power comes from a battery in the body. Passive tags come from the energy harvested from the reader’s radio waves.

IC is created on large semiconductor wafers. There are up to 40,000 IC on a single wafer. The IC on these wafers will be cut, separated by specialized personnel, and then connected to the tag antenna. The size of the IC determines the cost and the amount of power required to run it. The smaller the IC used, the lower the business’s running cost. With the advancement of technology, it is believed that IC designs will become smaller and smaller in the future.

RFID Tag Antenna

It is usually made of three main elements: copper, aluminum, and silver. The RFID tag antenna’s role differs depending on the type of tag. For active tags, the RFID tag antenna mainly focuses on transmitting signals. For semi passive or passive tags, it will reflect the signal. In the case of passive tags, the RFID tag antenna also collects energy from radio waves and provides it to the IC.

Matching the tag’s operating frequency can have a variety of shapes. There are general single dipoles, double dipoles, folded dipoles, etc.

It is generally deposited on the substrate by three methods. There are copper etching, screen printing, and foil stamping. Screen printing is by far the fastest and cheapest method. But the antenna manufactured by this method is also the least efficient. The other two are usually chosen to improve the efficiency of employees.

RFID Tag Substrate

It is the substrate that holds all the components together. Generally, RFID tag antennas are deposited or printed on the substrate. The IC is attached to that antenna. RFID tag substrates can be made of flexible or rigid materials. Most passive tags choose RFID tag substrates made of flexible materials.

When designing RFID tag substrates, one needs to consider more. They can withstand high temperatures, moisture, chemicals, or other corrosion. And whether they can withstand environmental conditions such as shock and abrasion. It is also essential in the selection of materials because the material may have an impact on the frequency of the antenna.

RFID Labels Application Scope

RFID labels have a wide range of applications. For the logistics industry, it can be used as cargo tracking in the logistics process. It can automatically collect cargo information. In the retail industry, it can provide real-time statistics on the sales data of goods so that the goods are always in stock. For the manufacturing industry, it will track production data in real time. It can better control the quality of products. It can better assist companies in achieving the goal of automated production. People also can use it in several industries, such as the apparel industry, Healthcare industry, automotive manufacturing, etc.

The popularity of RFID labels has brought many benefits to businesses. It increases employee productivity and reduces error rates. It allows companies to manage corporate assets better. It makes it easier for people to travel.
