In the current digital world, finding a secure method of identity verification has gained increased significance. The level of cyber threats is developing, and our efforts towards safety should follow suit. Near Field Communication (NFC) identity verification is one of the promising new technologies that offer effective and secure authentication. The blog explains how NFC Identity Verification technology has revolutionised the identity verification process across various sectors.
Near Field Communication (NFC) is a short-range wireless technology used to communicate between two devices when they are brought very close to each other, typically within 4 centimetres. NFC was initially designed to be used without a probe in a payment system, but it has been modified to fulfil various functions, such as identity authentication.
The NFC System is based on radio frequency identification (RFID) technology and can be used for bi-directional communication. In contrast to Bluetooth or Wi-Fi, NFC connections are formed automatically when the devices are in contact, i.e., the devices are unpaired. This convenient connectivity renders NFC especially suitable for fast transactions and authentication schemes.
NFC authentication is a system that certifies a person’s identity by utilising NFC technology to access and confirm the details of scheme documents through electronic identification schemes. This is done by embedding NFC chips that store personally identifiable information and biometric data on these documents, such as e-passports, national ID cards, and driver’s licenses, among others.
With the NFC System incorporated in identity checking systems, it offers a valid means to:
The technology represents a significant improvement over conventional verification mechanisms, which are less secure, inaccurate, and inefficient.
The Identity Verification Solution using NFC is a process comprising a few steps:
Document Authentication: This process begins when the user holds their identification document, which contains an NFC tag, against an NFC reader or a smartphone that supports NFC.
Data extraction: The NFC reader connects to the chip embedded in the document and extracts the data stored there, and this usually contains:
Digital Signature Check: This utilises the Digital Signature on the chip to verify that the authoritative party has not corrupted the document and is authentic.
Information: The possible data mentioned is validated against the visible printed information on the document to determine consistency.
Biometric Verification: In most instances, biometric verification will also be performed; the electrical measurement of the facial image in the chip will be compared to the user’s face in real-time.
Success: If the verification process is successful and all verification steps are completed, the identity verification process is accomplished, and the user’s identity is verified.
The entire process takes only a few seconds, making it both convenient.
The technology of NFC identity verification has been used in the following industries:
Globally, immigration agencies are increasingly using NFC identity verification to enhance security at checkpoints. The technology features e-passports that are fast and accurate in verification, thereby saving time and improving security.
NFC Identity Verification Solution can be integrated into front-end processes of banks and financial institutions as a way of customers being identified securely to comply with the KYC and Anti-Money Laundering (AML) rules.
The use of the NFC System in contactless check-in processes by hotels and airlines enables the fast and secure verification of guests using their electronic IDs, which is quicker in performance.
The NFC authentication used by healthcare providers ensures that patient identification is accurate and that only the intended patient receives access to their medical records, thereby preventing the outbreak of medical identity theft.
NFC-based verification systems have also been widely used to control file access in organizations, where traditional key cards are being replaced with more secure mechanisms of verification using digital identity.
The NFC verification is also used in various public services by government facilities, including voting, payouts, and license checks.
The NFC Identity Verification has many benefits compared to classical ones:
This is because cryptographic security infused into NFC chips renders them difficult to forge and even tamper with. The stored data is safeguarded by the use of digital signatures and encryption, making it difficult to hack into and replicate.
NFC technology also eliminates human error in manually verifying documents, as it is done automatically. The system can detect advanced forgeries that could otherwise not be visually identified.
NFC verification takes only a few seconds to complete, processing is significantly faster compared to manual verification. This functionality is especially essential when several people need to be covered, such as at airports or events with high attendance.
The implication of the hygienic identity verification that NFC technology offers is that it is a contactless technology; therefore, this aspect is critical in cases of post-pandemic situations where physical contact should be avoided.
NFC verification can be applied to various devices, starting with dedicated readers and standard smartphones. As a result, NFC verification can be affordable for both large and small organizations.
NFC checking helps organizations meet increasingly stringent identity verification policies with a secure and transparent verification process.
Challenges and Limitations
NFC identity verification has some hardships despite the benefits:
Document Compatibility
NFC does not apply to all identification documents that utilize NFC chips. Although the use of e-passports is everyday, most other types of identification do not have the NFC functionality.
Infrastructure Requirements
Using NFC verification systems requires investment in compatible hardware and software, which can be a drawback for small organizations or those in developing countries.
Biometric data acquisition and processing raise the issue of privacy, which should be addressed by integrating the use of adequate data protection and clear policies.
Although the short range of NFC is a security advantage, it may be a consideration when this technology is used. Additionally, when the chip is physically damaged, it may render NFC verification impossible.
Identity Verification Solution has not been widely used by many users before, which requires education and clear instructions to facilitate entry, as many people are unfamiliar with its use.
The future of identity verification by NFC is very optimistic, and some new roads can be noted:
With the introduction of more smartphones featuring NFC, we will have an extension of identity verification directly into the phones, thus enabling people to authenticate their identity through their phones.
Combining NFC verification with blockchain technology promises to create immutable records of verification events, further enhancing security and trust.
Advanced biometric features, such as liveness detection and behavioral biometrics, will be integrated with NFC verification to provide multi-layered security.
More types of identification documents will incorporate NFC chips, broadening the applicability of NFC verification systems.
Increased international standardization will enhance interoperability between various NFC verification systems, thereby facilitating global adoption.
Artificial intelligence will enhance NFC verification processes by improving fraud detection and automating complex verification decisions.
NFC identity verification represents a significant advancement in secure authentication technology. By combining the security of cryptographic protection with the convenience of contactless operation, NFC verification offers a robust solution to modern identity verification challenges.
As more identification documents incorporate NFC capabilities and more devices become NFC-enabled, we anticipate that this technology will become increasingly prevalent across various sectors. Organizations looking to enhance their security measures while improving user experience should consider implementing NFC-based verification systems offered by KYC Hub.
