1. How is RFID used in asset tracking?

Radio Frequency Identification (RFID) in asset tracking involves tagging items with RFID labels or tags. RFID readers capture data from these tags, enabling real-time monitoring of an asset's location and status. This streamlined process, integrated with databases, automates tracking, improves accuracy, and facilitates efficient inventory management in diverse industries.

2. How much information can an RFID tag or label store?

Passive RFID tags are powered by the energy received from the RFID reader and can store limited amounts of data, typically between 96 and 496 bits. The size of the RFID tag also affects the amount of information that can be stored. Smaller tags generally have less memory than larger tags, but new advancements in RFID technology are increasing the amount of data that can be stored on smaller tags making it a useful tool for asset tracking and management.

3. Does an RFID tag read through walls or people?

RFID tags typically cannot be read through walls or people. RFID technology relies on radio frequency signals for communication between the RFID reader and the tag. Solid objects, including walls and human bodies, can attenuate or block these signals, making it difficult for RFID readers to detect and read tags on the other side. For effective RFID communication, a direct line of sight or proximity between the RFID reader and the tag is generally required.

4. Can RFID be used for surfaces that are not flat?

Cintura Loop-Tag has been developed specifically to tag items that are otherwise difficult to tag such as cables, tubes, ropes, etc. This all-surface tag is well suited for different kinds of surfaces and can also be adjusted to perfectly fit different item diameters. These tags use radio waves to communicate with an RFID reader. They can be attached to cables and can provide real-time identification and tracking of the cables.

We proudly have introduced one of our innovation:CylTag™, designed specifically for Beer Kegs, Gas Cylinders and Chemical Drums . Our state-of-the-art RFID tag has been engineered to revolutionize inventory tracking and lifecycle management for businesses dealing with beer kegs and gas canisters suitable for various curvatures of the cylinder.

5. Do RFID tags work in high temperatures?

The high temperature can affect the performance of the tag's integrated circuit and antenna, potentially leading to reduced read range, communication errors, and even permanent damage. To address these issues, SIVA has developed high-temperature RFID tags (HT-HTP 4129 & HT-HTP 4215), which are specifically designed to operate in harsh environments and withstand temperatures. These tags are made with materials that are resistant to heat and feature a rugged design that helps to protect the internal components. Additionally, they may also have a protective casing or insulation to further enhance their performance in high-temperature conditions.

6. What is the frequency range of RFID tags and labels?

RFID tags and labels operate within different frequency bands, and the frequency range can vary. The most common RFID frequency bands are Low Frequency (LF), High Frequency (HF), and Ultra High Frequency (UHF). LF typically operates around 125 kHz, HF around 13.56 MHz, and UHF in the range of 860-960 MHz.

7. What is ETSI and FCC in the context of RFID tags?

ETSI (European Telecommunications Standards Institute) and FCC (Federal Communications Commission) are regulatory bodies that establish standards and regulations for electronic communication devices, including RFID tags. ETSI is responsible for setting standards in Europe, while the FCC oversees regulations in the United States.

8. What kind of RFID tags are used in cold chain temperature monitoring?

RFID tags used in cold chain temperature monitoring are typically equipped with temperature sensors that can measure and transmit data about the temperature of the products being monitored. These tags do not have a battery and rely on the energy from the reader to transmit data. These tags also have inbuilt moisture sensors that are designed to detect and report moisture levels in their immediate environment.

9. What is the difference between UHF, HF, and NFC technologies?

UHF (Ultra High Frequency) and HF (High Frequency) are two different radio frequency ranges used in RFID (Radio Frequency Identification) technology. NFC (Near Field Communication) is a subset of HF RFID technology that allows for short-range communication between devices.

10. Do dual frequency RFID labels work with metal assets?

Dual frequency RFID labels are radio frequency identification labels that are equipped with both high-frequency (HF) and ultra-high-frequency (UHF) chips. Yes, dual frequency RFID labels can work with metal assets, although their performance may be affected by the metal's presence. To ensure proper functioning of RFID tags on metal assets, SIVA has developed Ferro MOM 7035 Dual Frequency TE, a specialized "on-metal" tag, offered with an EM4425 chip, this versatile RFID label can be used to secure various types of indoor assets, anti-counterfeiting and product identification. These tags are designed to have a stronger signal and to better withstand the interference caused by metal surfaces.

11. Which industries use RFID technology?

RFID technology is widely used in various industries for asset management. Some of the industries that commonly use RFID for asset management include:

12. Are RFID tags ideal to track reusable shipping containers with high water content?

When it comes to tracking reusable shipping containers which are also referred to as returnable transport items with high water content, the ideal identification tags would be those that are waterproof and can withstand exposure to water and other harsh environmental conditions, tags such as, Re-load Pro 7320 are washable RFID tags designed specifically for reusable shipping containers like plastic crates & wooden pallets.

13. Can RFID tags be used for laundry management?

RFID tags used for laundry management are typically rugged and durable tags that can withstand the harsh environment of industrial laundry facilities. They are often designed to be resistant to high temperatures, moisture, chemicals, and mechanical stress. Lavanda™ by SIVA are RFID laundry tags with small footprint & good read range, The laundry tags robust design combats the industrial wash cycles for linens and other textiles, withstanding the rigors of repeated washings, cleaning chemicals, drying and ironing cycles.

14. How do tamper-proof RFID tags work?

Tamper-proof RFID tags often have physical or electronic mechanisms that make it challenging to remove or alter the tag without triggering a visible indication of tampering. This can include features like destructible materials, special adhesives, or electronic circuitry that detects tampering.
