What Are Hard Tags?

Hard tags are rugged identification tags made from materials such as ABS plastic, metal, polycarbonate, or epoxy-coated composites. Unlike paper or polyester labels, hard tags are engineered to resist extreme temperatures, moisture, chemical exposure, and mechanical stress.

Each hard tag can be embedded with:

• RFID (Radio Frequency Identification) chips for contactless tracking
• Barcodes or QR codes for manual or automated scanning
• Laser engraving or UV printing for permanent branding and identification

Their versatility makes them indispensable in manufacturing units, automotive plants, logistics hubs, warehouses, and outdoor industrial sites.

Applications of Hard Tags in Logistics and Supply Chain

1. Inventory Management

In logistics, where stock turnover is continuous, manual inventory tracking can lead to errors and inefficiencies.
Hard tags provide a permanent, scannable identity to pallets, containers, and bins.
With this system, businesses can:

• Track incoming and outgoing stock automatically
• Simplify stocktaking and cycle counting
• Prevent duplication or misplacement

Barcode Vault offers ABS and Polycarbonate RFID tags designed for long-lasting readability and high scan rates, even in dusty or outdoor warehouse environments.

2. Returnable Transport Item (RTI) Tracking

Returnable items like pallets, crates, and cages often circulate between suppliers, warehouses, and distribution centers. Without proper identification, tracking them becomes difficult.
Using Barcode Vault’s hard tags, companies can:

• Assign unique IDs to each transport item

What is RFID (radio frequency identification)?

What is RFID (radio frequency identification)

RFID, which stands for Radio Frequency Identification, represents a wireless communication method that harnesses electromagnetic or electrostatic coupling within the radio frequency segment of the electromagnetic spectrum. Its primary purpose is to provide a distinct means of identifying objects, animals, or individuals.

• How does RFID work?

In every RFID setup, you've got three main parts: a scanning antenna, a transceiver, and a transponder. When you put the scanning antenna and transceiver together, they make what's called an RFID reader or interrogator. Now, there are two kinds of RFID readers - fixed ones and ones you can move around (mobile readers). The RFID reader is like a device that's connected to a network, and it can be either something you carry around or something fixed in place. It uses radio waves to send signals that wake up the RFID tag. Once the tag wakes up, it sends a signal back to the antenna, and this signal gets turned into data.

The transponder is basically inside the RFID tag itself. How far the RFID tags can be read depends on things like what type of tag it is, what kind of reader is being used, the RFID frequency, and if there's any interference around from other RFID tags or readers. Tags with a stronger power source can be read from a greater distance.

§  What do RFID tags and smart labels refer to?

 RFID tags are made up of an integrated circuit (IC), an antenna and a substrate. The part of an RFID tag that encodes identifying information is called the RFID inlay.

There are two main types of RFID tags: 

• Active RFID -  An active RFID tag has its own power source, often a battery. 

• Passive RFID -  A passive RFID tag receives its power from the reading antenna, whose electromagnetic wave induces a current in the RFID tag's antenna.

There are also semi-passive RFID tags, meaning a battery runs the circuitry while communication is powered by the RFID reader.

Low-power, embedded non-volatile memory plays an important role in every RFID system. RFID tags typically hold less than 2,000 KB of data, including a unique identifier/serial number. Tags can be read-only or read-write, where data can be added by the reader or existing data overwritten.

The read range for RFID tags varies based on factors including type of tag, type of reader, RFID frequency, and interference in the surrounding environment or from other RFID tags and readers. Active RFID tags have a longer read range than passive RFID tags due to the stronger power source.

Smart labels are simple RFID tags. These labels have an RFID tag embedded into an adhesive label and feature a barcode. They can also be used by both RFID and barcode readers. Smart labels can be printed on-demand using desktop printers, where RFID tags require more advanced equipment.

RFID Tags

§  What are the types of RFID systems?

There are three main types of RFID systems: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). Microwave RFID is also available. Frequencies vary greatly by country and region.

·         Low-frequency RFID systems. These range from 30 KHz to 500 KHz, though the typical frequency is 125 KHz. LF RFID has short transmission ranges, generally anywhere from a few inches to less than six feet.

·         High-frequency RFID system. These range from 3 MHz to 30 MHz, with the typical HF frequency being 13.56 MHz. The standard range is anywhere from a few inches to several feet.

·         UHF RFID systems. These range from 300 MHz to 960 MHz, with the typical frequency of 433 MHz and can generally be read from 25-plus feet away.

·         Microwave RFID systems. These run at 2.45 Ghzand can be read from 30-plus feet away.

The frequency used will depend on the RFID application, with actual obtained distances sometimes varying from what is expected. For example, when the U.S. State Department announced it would issue electronic passports enabled with an RFID chip, it said the chips would only be able to be read from approximately 4 inches away. However, the State Department soon received evidence that RFID readers could skim the information from the RFID tags from much farther than 4 inches -- sometimes upward of 33 feet away.

RFID Frequiencies and Range

§  RFID applications and use cases

RFID dates back to the 1940s; however, it was used more frequently in the 1970s. For a long time, the high cost of the tags and readers prohibited widespread commercial use. As hardware costs have decreased, RFID adoption has also increased.

Some common uses for RFID applications include:

·         pet and livestock tracking

·         inventory management

·         asset tracking and equipment tracking

·         inventory control

·         cargo and supply chain logistics

·         vehicle tracking

·         customer service and loss control

·         improved visibility and distribution in the supply chain

·         access control in security situations

·         shipping

·         healthcare

·         manufacturing

·         retail sales

·         tap-and-go credit card payments

Passive RFID tags do not require batteries. In this example of passive RFID from Honeywell, battery-free tags in vehicles are used to collect tolls on highways.

RFID Vs. Barcodes  

Using RFID as an alternative for barcodes is increasing in use. RFID and barcode technologies are used in similar ways to track inventory, but there are some important differences between them.

RFID tags	Barcodes
Can identify individual objects without direct line of sight.	Direct line of sight required for scanning.
Can scan items from inches to feet away, depending on type of tag and reader.	Require closer proximity for scanning.
Data can be updated in real time.	Data is read-only and can't be changed.
Require a power source.	No power source needed.
Read time is less than 100 milliseconds per tag.	Read time is half a second or more per tag.
Contain a sensor attached to an antenna, often contained in a plastic cover and more costly than barcodes.	Printed on the outside of an object and more subject to wear.

RFID vs. NFC

Near-field communication (NFC) enables data to be exchanged between devices by using short-range, high-frequency wireless communication technology. NFC combines the interface of a smart card and reader into a single device.

Radio frequency ID	Near-field communication
Uni-directional	Bi-directional
Range up to 100 m	Range less than 0.2 m
LF/HF/UHF/Microwave	13.56 MHz
Continuous sampling	No continuous sampling
Bit rate varies with frequency	Up to 424 Kbps
Power rate varies with frequency	<15 milliamperes

RFID challenges

RFID is prone to two main issues:

·         Reader collision. Reader collision, when a signal from one RFID reader interferes with a second reader, can be prevented by using an anti-collision protocol to make RFID tags take turns transmitting to their appropriate reader.

·         Tag collision. Tag collision occurs when too many tags confuse an RFID reader by transmitting data at the same time. Choosing a reader that gathers tag info one at a time will prevent this issue.

RFID security and privacy

A common RFID security or privacy concern is that RFID tag data can be read by anyone with a compatible reader. Tags can often be read after an item leaves a store or supply chain. They can also be read without a user's knowledge using unauthorized readers, and if a tag has a unique serial number, it can be associated to a consumer. While a privacy concern for individuals, in military or medical settings this can be a national security concern or life-or-death matter.

Because RFID tags do not have a lot of compute power, they are unable to accommodate encryption, such as might be used in a challenge-response authentication system. One exception to this, however, is specific to RFID tags used in passports -- basic access control (BAC). Here, the chip has sufficient compute power to decode an encrypted token from the reader, thus proving the validity of the reader.

At the reader, information printed on the passport is machine-scanned and used to derive a key for the passport. There are three pieces of information used -- the passport number, the passport holder's birth date and the passport's expiration date -- along with a checksum digit for each of the three.

Researchers say this means passports are protected by a password with considerably less entropy than is normally used in e-commerce. They key is also static for the life of the passport, so once an entity has had one-time access to the printed key information, the passport is readable with or without the consent of the passport bearer until the passport expires.
