Security stickers, also known as security labels or void labels, are a critical component in the protection and authentication of products, documents, and assets. They serve multiple purposes, from preventing unauthorized access to ensuring the integrity of products during transport and storage. Here’s a detailed look into security stickers, their types, uses, and benefits.
Top Security Sticker Uses
Computer Hardware Security:
Computers are perhaps one of the most valuable assets of businesses as this electronic device contains valuable and sensitive data. With the introduction of general data protection regulation (GDPR), and the increasing number of data security breaches and frauds that can cause anything from access to personal or confidential details to impacting election results, securing electronic information has become more important. Security labels help protect the server and hardware access and confidential hard drives as well as escalate security breach issues.
Airline Security:
In a flight, there are hundreds of people aside from the cabin crew, and the safety of each one is crucial. Security labels work well in such situations to keep the environment safe. These powerful stickers alert the cabin workers of any unauthorized access to food or anything else. Additionally, these labels are numbered and barcoded individually on luggage upon check-in at the flight desk. This helps identify individual belongings.
Medicinal Products:
The counterfeiting of medical drugs is a risk for consumers’ health, and it is a massive economic loss as well for those manufacturers. The safety of these products is highly important, and it demands the utmost control of process flow from manufacturing to distribution. Security labels are one of the best ways to ensure that drug shipment is untampered during transit.
Ballot Boxes:
The election process may come around after every few years. It goes without saying, but this process demands the coordination of thousands of volunteers, public voters, and of course voting machines. There are possibilities of illegal interference with the process of election. Security labels eliminate the chance of election fraud by protecting confidential documents and ballots. These labels remain unopened until each vote can be securely counted.
Sensitive Documents:
Along with government and defense environments, several organizations have sensitive documents with future business strategies and client information at the workplace. Securing these documents from unauthorized access is the first priority. One of the best ways to ensure their safety is by using security labels on folders, stacks, and cabinets containing classified information. If the label has tampered, they will show evidence of unauthorized access or void marks left behind.
Clinical Laboratory Testing:
When conducting medical tests or experiments, it is difficult to identify and trace individual samples, and it is important that they do not mix or get the wrong label. Security labels are the perfect solution here. Small-sized non-residue labels can easily differentiate each sample. The labels not only identify an individual’s sample but also provide an easy and quick indication of tampering if that happens.
Affordability – Able to be purchased in bulk for a low price, security tags provide an obvious cost-effective solution for retailers. When related to the amount of money that you could potentially lose through theft, then the overall layout of a security system will seem extraordinarily little in comparison.
Quick and easy to use – As part of the excellent features of a security tag is, they are amazingly simple to fix onto a wide range of items, but extremely difficult to remove without a deactivator. Tags such as ink tags will ruin the product they are attached to when tampered with, or improperly removed. This is a benefit denial technique, since the item will be physically damaged, and unsellable on any resale market.
Easy to deactivate
A deactivator can remove a security tag in seconds, cutting down on the time in which your customers need to wait for their products. Different security tags may need different deactivators
Provides retailers with some peace of mind
The last thing you want to worry about is yet another aspect of your already-busy job. With security tags accessories, you and your staff will also be reassured that they are shopping in an environment that is not likely to be infiltrated.
Reliability
Security tags are extremely strong and durable and cannot simply be removed without using a deactivator. Thankfully, various types of security tags and devices will only set the alarm if tampered.
Main Function of Security Label
Maintain product authenticity
Safety labels can help ensure that the product a consumer receives is the original product from the manufacturer. This can be done by using unique and difficult to imitate security features. Consumers can determine whether an item has never been opened before by checking the label.
Sealing the boltholes
Security labels can be used to cover boltholes on products. The label makes it impossible to open the bolt without damaging it. Label damage can be a clue to unauthorized disassembly or repair attempts.

Indicates the warranty period
Security labels can serve as a marker for the product’s warranty period. The label contains information about the warranty period, so consumers can know how long the product is still covered by the warranty. This can help consumers submit warranty claims if the product is damaged during the warranty period.
Proving the originality of the product
A security label can be proof that the product is genuine. In the event of a dispute between the consumer and the manufacturer, the security label can be used as evidence to prove that the product is genuine.
Types of Security Sticker
Hologram Sticker
The most commonly used kind of security labels are holograms. When seen from different angles, hologram stickers display images or patterns that change color and appear in 3D. Because of this characteristic, hologram stickers are particularly effective at preventing the counterfeiting of products. In addition, hologram stickers can enhance brand recognition and become a badge of authenticity for products.
Void Labels
Void labels are a type of security label that serves to prevent product theft and dismantling. Void labels will become damaged or discolored when removed, leaving a trail of “Void” messages. This message will be an indicator that the product has been opened or disassembled, thereby preventing theft and dismantling of the product. Additionally, void labels can also be used as an indicator of product damage or manipulation.
QR Code / Barcode Stickers
QR codes, or barcode stickers, are a type of security label that serves to store product information. Stored product information can include serial numbers, production dates, or website links.
Tamper-Evident Seals
Tamper-evident seals are a type of security label with functionality to prevent product packaging from being dismantled. Tamper-evident seals will break or leave traces when opened, which will be an indicator that the product packaging has been opened or manipulated. This can prevent damage to product contents and ensure product safety.
Security Holographic Overlay Stickers
Security holographic overlay stickers are a type of security label that combines a hologram with a transparent sticker. This combination provides a unique visual security effect that is difficult to imitate. This can increase product safety, serve as a marker of authenticity, and prevent product counterfeiting. Additionally, security holographic overlay stickers can also be used for branding and product aesthetics.
RFID (Radio Frequency Identification) Labels
One kind of security label that makes use of radio frequency identification (RFID) technology is the RFID label. RFID technology reads and writes data using radio waves. A tiny chip on RFID labels is capable of storing product data. You can use radio waves to obtain this product’s information.
Serial Number Stickers
Serial Number Stickers provide security by making each product unique. This unique serial number is difficult to counterfeit, so it can be used to identify genuine products and prevent counterfeiting. Serial Number Stickers can also be used for product tracking, allowing manufacturers to track products throughout the supply chain.
Scratch-Off Security Labels
Scratch-Off Security Labels provide security by hiding important information under a scratchable layer. This information may be a verification code, gift code, or other information necessary to verify the authenticity of the product. Scratch-off security labels can also be used for promotions, as consumers can scratch off the coating to reveal information of interest.
How do Security Sticker Work?
Application
The security label is applied to the product or packaging. This step involves choosing the right type of label that suits the surface material and environmental conditions the product will be exposed to.
Activation
Activation is a crucial step for certain types of security labels, especially those involving electronic tracking or digital verification (like RFID or QR codes). This involves programming the label with specific information or linking it to a database for tracking and authentication purposes.
Detection
When an attempt is made to access the product or information, the security label detects this interaction. This detection is a physical change in the label’s appearance for tamper-evident labels.
Response
Upon detection of tampering or unauthorised access, the label responds according to its design. Tamper-evident labels might leave a “VOID” message or show visible signs of damage.
How to Choose a Security Sticker?
Assess the Surface and Material of the Product
Choose adhesives based on the product’s surface.
For plastics, opt for adhesives that handle bending; metals require abrasion-resistant options. Automotive parts exposed to oil need labels made from chemical-resistant materials like polyester.
Identify Security Needs
The security level depends on the risk and application. Basic tamper-evident labels work for low-risk items. High-value products need advanced features like holograms or unique serial numbers for tracking and authentication.
Consider Environmental Factors
Select labels that are durable against specific environmental conditions. UV-resistant coatings are essential for outdoor use to prevent fading, while chemical environments demand labels made from materials that resist corrosion.
Ensure Regulatory Compliance
Ensure compliance with industry standards. Pharmaceutical labels should align with FDA guidelines, including tamper-evident features. Food packaging requires clear allergen and nutritional information, following food safety regulations.
Customise for Branding
Look for labels incorporating the brand’s logo and colours to enhance visibility and authenticity. Incorporating variable data printing allows for unique identifiers like QR codes on each label for added security and traceability.
