Tamper-evident labels are RFID labels specifically designed to detect and indicate tampering attempts. These labels are vital to maintaining the integrity of the product, ensuring any unauthorized access or interference is promptly identified. These labels can detect physical tampering, providing real-time alerts. Each label has a unique identifier, ensuring authenticity and traceability. These labels not only help protect product authenticity but also increase supply chain security and transparency. This article will introduce the types of tamper labels and their differences, discuss the advantages of the NTAG® 213 TT NFC label chip, and show some cases of actual use of electronic tamper labels.
Types and differences of tampered labels
There are roughly the following types of common tamper-evident labels on the market. Each type of label has its own unique characteristics and application scenarios in terms of anti-counterfeiting, anti-theft and anti-tampering.
- The first type: physical tamper-evident labels. This type of label incorporates physical safeguards either on the label itself or on its materials. For example, destructive tear-off safety seals on product packaging. Once the label is torn or removed, it will leave obvious traces of damage and cannot be reused. Foods in daily life often use this type of label. Physical labels also include hierarchically designed labels. After layered labels are attempted to be torn off or damaged, obvious marks will be left on the location of the label, making it difficult to reuse or repair. It is especially suitable for scenarios that prevent label transfer and reuse, such as electronic products and luxury goods.
- The second type: thermal tamper-resistant labels. The material of this kind of label is sensitive to temperature changes. Once exposed to abnormal temperatures, the label will undergo irreversible color changes or the text will disappear. It is commonly used in products that need to maintain temperature control, such as food, pharmaceuticals and cold chain logistics.
- The third type: optical tamper-evident labels. Such labels use optical effects (such as optically variable inks or holographic images) to enhance tamper-resistance. Labels will display different images or colors at different angles or under light, and are often used for high-end brands and luxury goods to enhance the visual recognition and anti-counterfeiting of products.
- The fourth type: electronic tamper-evident labels. This kind of tag contains an electronic chip of RFID or NFC and has built-in tamper detection function. When the tag is physically tampered with or destroyed, the tamper detection loop inside the chip is triggered, recording the tampering event and reading it through the NFC device. It is widely used in supply chains that require high security and real-time monitoring.
NTAG® 213 TT NFC label is a type of electronic tamper-evident label. Electronic tamper-evident labels also have a more prominent advantage over the other three labels mentioned above. What are the advantages? Let me reveal the secret below.
Features of NTAG® 213 TT NFC label
NTAG® 213 TT NFC label is an electronic NFC label with anti-tampering function, which is widely used in fields such as product anti-counterfeiting and security sealing. The tampered labels we just introduced can ultimately be divided into two types according to type: one is the completely destroyed type mentioned in the first three, and the other is similar to the NTAG® 213 TT NFC label that can detect tampered information. Type (often referred to as “TT” or “Tamper Cycle” type labels), labels of this type are reusable and support repeated editing, identification, and reading.
NTAG® 213 TT NFC label is usually rectangular or round in appearance, made of flexible material, with embedded NFC chip and antenna for transmission. The tag memory is 144 bytes and supports read-only mode. It provides advanced AES-128 encryption operations and protects stored data through 32-bit passwords, limiting the number of error attempts. It is very professional in enhancing brand protection functions and improving anti-counterfeiting capabilities. The tag structure adopts a double-ring design with two built-in coils, one for regular NFC communication and the other for detecting tampering. If the tamper coil is tampered with, the tag will still function normally, but the tampering event will be logged and reported, ensuring users can detect unauthorized openings. It fully complies with the NFC Forum Type 2 and ISO/IEC14443 Type A specifications for RFID applications, can support the ISO/IEC 14443-A protocol, and is compatible with all NFC devices. Users do not need to use special equipment, just use NFC devices such as smartphones. Label information can be easily obtained.
NTAG® 213 TT NFC label can even help consumers get a better brand experience. How is it done?
Create a better brand experience
Brand owners can engage consumers by writing contextual information on labels that prompt real-time product status, which can help build deeper, more lasting consumer relationships.
For example, writing product information, expiration date, provenance, discounts and other pre-sales information can report the status of the product or packaging seal to consumers to verify whether the items have been properly handled.
Furthermore, you can write some after-sales content such as services, membership systems, and social networking. When the user reads the tag, the two-state application is activated. Such programs can be used to emit special sound bites, unlock new characters in toy products, and guide users to like them on social media.
Electronic Tamper Tag Use Cases
Electronic tamper labels have shown great potential and effectiveness in practical applications. For example, the anti-counterfeiting labels used by Adidas.
Adidas launches its limited edition design sneakers every once in a while, and most of the shoes have anti-counterfeiting labels similar to the NTAG® 213 TT NFC label. By scanning the label, consumers can verify the authenticity and unique product number of the product on the official website.
Another common area of use is in the alcohol market. High-end wine brands, such as Château Lafite Rothschild and Hennessy, use tamper-proof NFC labels on the packaging of their reserve wines. Once a package’s label is compromised, the tampering is documented.
FAQs
1. What is the difference between tamper-proof and tamper evident?
- Tamper-proof: The main purpose is to ensure that tampering cannot occur at all.
- Tamper evident: Use some presentation method to provide obvious evidence that the item has been tampered with to prove whether the tampering has occurred.
The former is for prevention and the latter is for detection.
2. Does the NTAG® 213 TT NFC label need to be powered on before it can be used?
No power required. It is a tag containing a tiny chip that works passively.
The information can be read by touching the tag with an NFC-enabled mobile phone or other electronic device.
