Asset tags and their designs
Asset tags made from various materials and for various surfaces are used in just about every industry. The types of tags range from the humble Barcode label to QR (Quick Response) codes, RFID, GPS or Wi-Fi technology. The purpose of tagging your valuable assets, tools and equipment is to reduce human error, reduce asset “misplacement” and automate certain business processes.
Asset labels or tags typically “stick-on” to assets using industrial adhesive backing and can be tamper-evident. The most common asset tag materials are anodized aluminium or laminated polyester. With the asset tag design (what you see on the tag itself) including a company logo. Organisations can colour-code their tags or add a border to the labels, providing a contrast to the equipment.
On the other hand, there is a variety of tags that do much more than uniquely identifying an asset. In this article, we look at the different types of tags/labels. The materials used and environments where industries put these asset tags to use.
Why asset tags are important
Organisations purchase hundreds of different types of assets, tools and equipment for the successful operation of their tasks. Often these assets circulate within different departments or across different locations, and even countries.
Moving assets around an organisation increase the chance of assets being misplaced, lost or even stolen. But not utilising your assets to their fullest doesn’t make good business sense either. And this is where asset tracking comes into play.
Tagging or labelling your high-value assets, tools and equipment is a visible theft deterrent and a unique identifier. That can be used for asset tracking to reduce loss and provide easy physical auditing.Asset auditing benefits
Adding this unique identifier to an asset management system allows you to record and store all sorts of data about your assets. With information being accessed via Web, Cloud and Mobile Apps, asset tracking streamlines your business workflows.
Tagging your assets serves as the foundation for an asset tracking solution. Enabling organisations to monitor equipment usage. Including planned regular maintenance and repairs to maintain compliance. Streamlining reporting, re-ordering and optimising operations.
- Asset tagging makes it easier to perform physical audits for compliance with regulatory bodies
- Standardises asset identification so employees can easily identify and locate assets
- Lowers the risk of misplacement and theft
Asset tags and security
While some asset losses are due to mismanagement and poor tracking, theft is a serious concern in most industries. Barcodes themselves cannot deter theft, they can be tamper-evident. With anti-theft designs (tamper-evident or tamper-proof materials). Making detection easier.
Some barcodes have an invisible passive RFID chip inside the label (think of retail stores) that can trigger an alarm when the item moves through an RFID receiver (shop doorway or chokepoint).
Asset tags are overt methods to alert thieves that your assets are protected, being tracked and are not safe to steal!RFID asset tracking
What to consider when purchasing asset tags
Selecting the right types of asset tags/labels for your applications is crucial for the longevity of your asset management system. With many different types of asset tags, materials, security and durability considerations. Selecting the right asset tags for your business needs can be challenging.
Some asset tags can withstand exposure to the harshest chemicals and solvents, abrasion, salt spray, paint, oil etc. Aluminium tags and rigid plastic tags have a long-standing reputation for durability. Which types of tags or labels you choose will depend on:
- where assets are located (indoor/outdoor)
- the environment they are exposed to (chemicals, water)
- how precise you want the asset’s location to be
- where you attach the asset tag (placement visible or not)
- the surface of the assets to be tagged (flat/curved, metal)
How precise must location data be? Do you need to incorporate barcode tagged assets into your asset register as well as RFID? Do you want to track asset movement at certain points or locations, such as high-security areas? These are some of the questions that need discussion in order to obtain the desired end result.
Tamper-evident asset tags
Organisations working with high-value items need to implement strict asset tracking to protect expensive equipment from theft. Asset tags for this purpose can be “tamper-evident” and break apart if someone attempts to remove it from the asset’s surface. Trying to pry a tamper-evident tag off an asset may damage the tag, but not remove it.
Tamper-evident tags are great for detecting any attempt to pilfer items. A common use for these tags is high-value assets, like laptops, computers and printers.
Coloured asset tags
Asset labels and tags may be coloured such as blue, red and yellow. Colour coding of asset tags is sometimes used as an effective means of quick visual identification of ownership, departmental responsibility or value (such as red tags for high-value and/or sensitive assets).
There is a wide variety of identification technology available today. Customised polyester, aluminium, stainless steel barcode labels, and RFID tags suitable for every type of environmental application. From an indoor situation right through to labels that withstand the most extreme environments.Different tagging applications
Types of barcode and QR code technology
A Barcode label is a machine-readable data representation which is used to store short descriptions about items which can be read by scanners and/or mobile apps for asset and inventory management. The most common and broadly supported standards are 1D Code 39 and Code 128, and 2D QR codes, which enable the encoding of a greater amount of data. QR codes consist of tiny black Squares arranged across a square space and can be scanned easily by a smartphone camera.
QR codes are everywhere! You can find them printed on the packaging of your latest gadgets and included in presentations at conferences. People and companies use them to store and distribute all kinds of information, in a manner that is quickly accessible to anyone with a smartphone.
Surface type for labels
Barcode labels are popular because they can be attached to any sort of equipment and surface (even metal) with minimal infrastructural spend. Which is why they are a good option for small business asset management looking for low upkeep costs.
Plastic rigid and flexible materials
Plastic tags are suitable for mostly indoor use. Where the tag is required to adhere on a variety of difficult surfaces or in applications where occasional exposure to water and mild detergents is expected.
Metal rigid and flexible materials
Rigid aluminium barcode tags are highly durable and backed with a high-performance acrylic adhesive. Holes can be drilled for rivets or other forms of attachment (other than adhering to the surface of the asset). These tags are recommended for flat surfaces due to the firmness of the tag. And are suitable for harsh industrial and external environments.
Foil barcode labels
Aluminium foil barcode tags are highly durable, bendable and backed with a high-performance acrylic adhesive. These tags are recommended for curved and flat surfaces as they are flexible and adhesive enough to stick to uneven surfaces. They are also able to withstand abrasion, chemicals and harsh weather conditions and are suitable for harsh industrial and external environments.
Benefits of barcode labels
Barcode labels are a valuable and viable choice for businesses looking to improve efficiency and reduce overheads. Both cost-effective and reliable, barcodes allow for:
- Barcodes eliminate the possibility of human error
- A barcode scan is fast and reliable
- Barcodes are inexpensive to design and print
- Barcodes are extremely versatile
- Inventory control improvement; barcodes make it possible to track inventory so precisely, inventory levels can be reduced
- Both inexpensive and user-friendly, barcodes provide an indispensable tool for asset, tools and equipment tracking
Types of RFID tagging technology
Asset tags designed for RFID are generally focused specifically on both off-metal and on-metal assets. RFID asset management, using RFID tags is a worthy but slightly more expensive solution. We recommend testing to ensure adequate read range. RFID asset tags are a good option for organisations that use expensive or mission-critical equipment. RFID tags transmit information in the form of radio waves and don’t have to be in the reader’s sight to be scanned.
Two main types of RFID tags
Passive RFID tags; these do not have a power source built-in and are powered from the signal carried by the RFID reader. Passive RFID uses high-power readers and battery-free tags and is often used to track assets that go through a chokepoint such as a doorway.
“Semi-active” and “battery-assisted” are also applied to this type of tag. “Battery-assisted” is probably the best term, since it most clearly explains this type of tag requires power to function.
Active RFID tags; have a built-in power source, and their behaviour can be compared to a beacon. These can operate at a greater distance and at higher data rates. These tags have a limited life (longevity of battery) and higher cost. Please note Hardcat capabilities are with passive tags currently.
RFID on-metal asset tags
Metal surfaces reflect and create interference for RFID. This means the average RFID tag isn’t able to receive power and transmit information. Specific “on metal” RFID tags will work around this issue with technology that allows RFID to work when attached to a metal surface.
As long as you choose the correct RFID equipment for your situation and application, you won’t need to worry about interference from metal. RFID on-metal tags are perfect for equipment tracking. With the recent developments in RFID technology, the possible applications of metal mount RFID tags are expansive in scope.
The metal RFID tag, something thought impossible just a few years ago is on the cusp of changing the durable RFID landscape. Fusing the strength and longevity of a metal asset tag with the technological power of RFID.Best practice guide: RFID
Applications may have different or similar uses for tags; one is successful using passive RFID tags, and the other using barcode labels. The versatility of the tags and the applications are your deciding factors.
Benefits of RFID asset tags
- Automation – system requires minimal manual handling once up and running
- Efficiency, read rate and reduced human error
- Line of sight is not required and items can face any direction, as long as they are in the read range
- Durability – extensive range of RFID tags available dependent on the environmental conditions and tags are selected to match the project
- Security – RFID tags can be internally attached ensuring they are protected from removal and damage
Ensure asset tag scanner compatibility
The most common methods of reading asset tags are with hand-held, hands-free or fixed mount scanners/readers and mobile phones. Most scanners can read common linear symbologies, such as code 39, UPC, EAN, Code 128 and QR if it is enabled in the scanner. High-performance next-generation RFID readers scan RFID and 1D/2D barcodes and are the modern alternative for today and tomorrow.
Difference between a barcode scanner and an RFID reader
A barcode scanner collects information from barcode labels using a light that is reflected on a series of black bars (or tiny black squares in QR codes) to read the barcode label. Whereas RFID scanners or readers use radio waves, that can pass through solid objects to read the tag. Meaning an RFID tag can be hidden from sight but still be readable.
While both devices collect information from tags and/or labels, an RFID reader can collect information from both RFID tags and 1D/2D (QR codes) barcode labels. Allowing for a mix of RFID tags for high-end assets and the more economical barcode labels for other equipment.
Tip; when selecting a specific symbology for an asset tagging application, you need to consider the capability of your scanning hardware to read the tags. Most scanner manufacturers usually ship new scanners with most symbologies disabled, so make sure the symbology is enabled before attempting to scan.Talk to us about your hardware needs
