RFID (Radio Frequency Identification) is a non-contact automatic identification technology that uses radio signals to automatically identify target objects and obtain relevant data. The identification process requires no manual intervention and can operate in various harsh environments. RFID technology can identify objects moving at high speeds and can simultaneously recognize multiple tags, making it fast and convenient to use.
1. It can identify individual, highly specific objects, unlike barcodes, which can only identify categories of objects.
2. It uses radio frequency signals, enabling data to be read through external materials, whereas barcodes require laser scanning to read information.
3. It can read multiple objects simultaneously, whereas barcodes must be read one at a time. Additionally, RFID can store a significantly larger amount of information.
Biometric Technology is a method of identity authentication that utilizes human biological characteristics.
Biological traits are unique (different from others), measurable, and can be automatically identified and verified. These traits are categorized into physiological characteristics and behavioral characteristics. Biometric methods share three common features:
1. Universality – Everyone possesses them.
2. Uniqueness – They differ from person to person.
3. Permanence – They do not change over time.
Physiological characteristics used for biometrics include hand shape, fingerprints, facial features, iris, retina, pulse, and ear shape. Behavioral characteristics include signatures, voice patterns, and keystroke dynamics.
Based on these features, many biometric technologies have emerged, such as fingerprint recognition, palm geometry recognition, iris recognition, retina recognition, facial recognition, signature recognition, and voice recognition. However, some methods are still in the experimental stage due to high technical requirements, while others face challenges in commercialization because of stringent environmental demands, limiting their widespread adoption.
For instance, iris recognition and retina recognition are highly secure in terms of safety, but the process of extracting biological templates requires optical scanning of the iris or retina. This procedure can cause discomfort or even harm to some people's eyes. As a result, these methods are typically reserved for scenarios requiring exceptionally high-security standards.
RFID and Biometric Technologies are both automatic identification methods that have emerged to meet the need for fast and accurate identification of mobile people and objects in real-life scenarios. The concept of mobility encompasses various aspects, such as large quantities, frequent movement, potential changes, multiple sources and destinations, orderly flow, and time constraints. Relying solely on one identification technology cannot fully address the complex requirements of modern life.
The integration of RFID and biometric technologies has led to the development of security products that combine both methods. For example, access control systems now incorporate RFID modules, fingerprint recognition modules, and facial recognition modules to enable multi-level authentication mechanisms, meeting the identity verification needs under different security levels.
RFID technology is used for data collection across different stages of asset and cargo tracking, while biometric technology ensures both physical security and the digital safety of cargo information. This combination effectively achieves the goal of securely and systematically managing people, assets, materials, and operations.
New business models often gain user acceptance through innovative products or services, eventually expanding existing markets or even creating entirely new ones. With the continuous advancement of RFID and biometric technologies, along with rising demands for higher and more precise security standards, the integration of RFID and biometrics is undoubtedly a market inevitability. It may even evolve into one of the most critical technological applications in the security industry.
Biometric RFID cards combine something you have (the card) and something you are (biometric features), providing dual-factor authentication:
1. Even if the card is lost, unauthorized users cannot access data or permissions without biometric verification.
2. Biometric information is typically encrypted and stored within the chip on the card, preventing duplication or tampering.
A biometric passport, also known as an e-passport or smart passport, integrates biometric technology and RFID chips. It is designed to enhance border security and processing efficiency and is widely adopted globally.
The fundamental principle of this system is to first collect the passport holder's biometric data and store it in the RFID chip. During border crossing, the system captures the traveler's biometric information on-site and then compares it with the biometric data stored in the RFID chip of the biometric passport for identity verification.
1. Fast-Track Processing - Utilizes RFID technology to speed up border crossing without manual intervention.
2. High Security - Equipped with encryption engines and anti-tampering measures, making it difficult to forge.
3. Reliable Authentication - Ensures accuracy through biometric verification methods such as facial recognition, fingerprints, and iris scanning.
4. Versatile Applications - Can be used for passports, visas, credit cards, and other machine-readable documents.
This system combines iris recognition and RFID technology to efficiently manage firearms and their users, ensuring security and transparency.
1. Firearm Management: Each firearm is embedded with a unique RFID chip that records detailed information (origin, model, condition).
2. Identity Verification: Officers must undergo dual verification with iris recognition and an RFID card to check out a firearm, ensuring the correct firearm is assigned to the correct individual. The same firearm must be returned after the task is completed.
3. Information Traceability: The system logs usage and maintenance records, enabling quick tracking in case of firearm malfunctions or loss.
This technological model enhances the efficiency of security management for both people and assets and can be widely applied to other public safety fields.
Technologies based on finger skin surface features can be subdivided into 3 categories: optical sensing methods, DC capacitive sensing methods and thermoelectric strip sensing methods. Recognition is mainly carried out through the characteristics of the finger surface.
The extracted biometric data (e.g., fingerprints) are stored in an RFID card, which serves as a benchmark for identification and is kept by the cardholder. In security check or other occasions where identity confirmation is required, the biometric features (e.g. fingerprints) are extracted on-site and the biometric data stored in the RFID card is read with a reader, and a comparison of the two allows for a quick identification of the identity. The combination of RF card technology and biometric identification technology makes biometric identification further practical and popular, and also makes RFID technology in the security to obtain a better guarantee.
Speech recognition is based on the principle of transforming a speaker's voice into a digital signal and comparing its voice characteristics with a stored reference voice of a speaker to determine whether the voice is that of a person whose voice information has been stored, thereby confirming the identity of the speaker.
1. Activate the Card
First, you need to activate the biometric card through the registration process. This typically involves entering your personal information and biometric features (such as fingerprints, iris, or facial images) into the system. This information is stored in the card’s RFID chip and encrypted for security.
2. Insert or Scan the Card
When using the biometric card, you generally need to insert it into an RFID-enabled reader or bring it close to a scanning device (such as an access control system or a bank terminal). The card will automatically transmit the stored information.
3. Biometric Verification
To complete identity verification, the system will scan your biometric features (such as fingerprint scanning, iris scanning, or facial recognition) to confirm whether you are the legitimate holder of the card. The biometric device typically compares the real-time captured features with the biometric data stored on the card.
4. Permission Verification
If the card information and biometric data match, the system will verify your identity and grant the corresponding access privileges. These may include entering restricted areas, making payments, or obtaining control of devices.
5. Complete the Operation
Once identity verification is successful, you can proceed with the relevant operation, such as entering a secured area, conducting financial transactions, or operating devices. Any attempt that fails the verification will be rejected, ensuring security.
6. Data Protection
Biometric information and card data are typically stored in an encrypted form to prevent illegal copying or tampering. If the card is lost or stolen, the system can lock the card and re-register the biometric features to ensure security.
1. Enhanced Security: Biometric technologies like fingerprint and facial recognition are highly unique and hard to replicate. Combined with RFID’s contactless reading, they greatly enhance security. For instance, storing biometric data on RFID cards allows quick identity verification in security checks.
2. Convenience: RFID cards enable contactless reading without manual intervention. Paired with biometrics, they allow fast and easy identity verification by simply bringing the card near a reader.
3. Versatility: RFID works reliably in various environments, from harsh industrial settings to retail. Combined with biometrics, it suits high-security applications like access control, cargo tracking, and monitoring.
1. High Cost: RFID tags and readers are relatively expensive, especially for large-scale deployment, requiring significant investment. Biometric devices and maintenance also add costs, which may burden small and medium-sized businesses.
2. Privacy and Security Risks: RFID’s wireless transmission can be intercepted or tampered with, leading to potential data breaches. Although encryption and privacy protection measures can reduce risks, privacy threats still need attention.
3. Technical Limitations: RFID may face challenges in certain environments, such as interference from metal objects blocking radio waves, causing reading errors. Biometric methods like iris and retina scans, while highly secure, have complex processes and may cause discomfort, limiting their use cases.
RFID and biometrics as two emerging intelligent identification technology has its own advantages, biometrics based on the human body's own physiological characteristics of human identity identification, with high security features, in the field of human identity authentication has a wide range of applications; RFID without contact and artificial intervention, in the management of goods has a unique advantage. The combination of RFID and biometrics will greatly strengthen the security management of “people and things”, and has a very large market application space.
