What is electronic identity verification (eIDV)? Learn how digital ID checks work and why they’re replacing manual verification.
Electronic identity verification
Turning your face toward a smartphone camera or snapping a photo of an ID has become a familiar part of digital life. Electronic identity verification (eIDV) is steadily gaining traction, but despite its growing visibility, it is still far from universal adoption.
Recent industry research shows that a significant share of businesses worldwide continue to verify identity documents manually, even in remote onboarding scenarios such as video calls or post-upload human reviews. This highlights a clear transition phase: while eIDV technology is widely available, not all organizations fully trust it or have integrated it end to end. At the same time, the technology itself, although highly advanced, is still evolving.
So what exactly is electronic identity verification? How does it work, and why is it increasingly replacing traditional identity checks? Below, we explore the fundamentals of eIDV, its core components, and the trends shaping its future.
What is electronic identity verification?
Electronic identity verification is the digital evolution of traditional ID checks. Instead of relying on human judgment, it uses software and hardware to authenticate identity documents and confirm a person’s identity.
A modern eIDV system typically combines two core elements: document verification and biometric verification.
Document verification focuses on the authenticity of the ID itself. Specialized software can automatically identify the document type and issuing country, verify its physical presence, read printed and electronic data (including RFID chips), and detect signs of alteration or fraud.
Biometric verification, in turn, confirms the identity of the person presenting the document. Most commonly, this involves facial recognition, matching a live selfie to the photo stored in the ID. In higher-security scenarios, fingerprints or iris data stored in the document’s chip may also be used as an additional verification layer.
Traditional identity verification vs. eIDV
Traditional identity verification relies on a human examiner visually inspecting a physical document and comparing the photo to the holder. While still used in many environments, this approach is increasingly being replaced by automated methods, and for good reason.
Electronic verification delivers significantly higher efficiency. Automated systems can complete verification in seconds, while manual checks often take minutes. A prime example is NFC-enabled passport reading, which enables fast traveler processing at airport e-gates.
eIDV systems can also access and verify elements that are invisible to the human eye. Many modern IDs rely on cryptographic security embedded in chips or digital credentials, something no visual inspection can validate. Automated solutions can verify chip data and digital signatures directly against issuing authorities.
Biometric accuracy is another advantage. Instead of subjective visual comparison, eIDV performs precise biometric matching between live captures and securely stored reference data, including facial images and, where permitted, fingerprints or iris scans.
Crucially, eIDV enables remote identity verification. Customers can prove their identity online by scanning documents and completing biometric checks from their own devices, eliminating the need for physical presence.
Finally, security is strengthened through backend validation. Zero-trust architectures ensure that critical checks, such as chip authentication and signature verification, are repeated on secure servers, reducing the risk of client-side manipulation.
Key components of electronic identity verification
The full potential of eIDV becomes evident when verifying modern identity documents both physical and digital, that rely on cryptographic protection. These include ePassports, electronic national IDs, mobile driver’s licenses, and digital identity credentials.
RFID chips and machine-readable data
Most electronic IDs contain a contactless RFID chip that stores personal data and biometrics. In ePassports, this includes printed biographical data, a digital facial image, and often fingerprints. These chips follow international standards such as ICAO Doc 9303 and ISO 18013 and communicate via NFC at 13.56 MHz.
Understanding data groups
Chip data is organized into structured files known as data groups. For ePassports, the Logical Data Structure defines groups such as:
- DG1 for personal details and document number
- DG2 for the facial image
- DG3 for fingerprints (if present)
- DG4 for iris data (if present)
Additional groups store issuance details, digital signatures, and cryptographic keys. This structure allows differentiated access rights, for example, enabling basic verification while restricting biometric access to authorized entities.
Alongside chip data, eIDV systems also read the machine-readable zone printed on documents. The MRZ provides essential identity data and plays a critical role in securing chip access by helping generate encryption keys.
Secure access protocols: BAC and PACE
To protect chip data, secure communication must be established between the document and the reader.
Earlier eIDs rely on Basic Access Control, where encryption keys are derived from MRZ data. This ensures that only someone with physical access to the document can read the chip.
Newer documents use Password Authenticated Connection Establishment. PACE employs stronger cryptography while still relying on document-specific information such as MRZ data or a Card Access Number. As a result, it offers significantly improved protection against interception and brute-force attacks.
Cryptographic validation and authentication mechanisms
Reading chip data is only the first step. Its authenticity must also be verified.
Every electronic ID includes a digitally signed Document Security Object containing hashes of all data groups. These signatures are created using certificates issued by national authorities.
Passive Authentication verifies that chip data has not been altered and originates from a legitimate issuer by validating hashes and digital signatures.
In contrast, Terminal Authentication ensures that only authorized readers can access sensitive data such as fingerprints. The reader must prove its authorization to the document before access is granted.
To prevent chip cloning, eIDs also use Active Authentication or the more advanced Chip Authentication. These mechanisms confirm that the chip is original and establish secure session keys for data exchange.
Biometric verification
Biometric matching is essential for confirming that the document holder is the rightful owner. Facial biometrics are the most widely used, as high-quality facial images are stored directly in the chip.
In line with updated ICAO requirements, document readers must support the new ISO/IEC 39794-5 facial image standard by 2026. This format includes richer biometric metadata, and full adoption by issuing authorities is expected by 2030.
During verification, the user provides a live facial capture, which is compared to the chip’s stored image. Liveness detection ensures the capture comes from a real, present person rather than a photo, video replay, or mask.
A typical electronic IDV workflow
Consider a remote onboarding scenario using an ePassport:
- The user scans the MRZ or Card Access Number.
- A secure NFC connection with the chip is established using BAC or PACE.
- Chip data is read and validated through Passive Authentication.
- Active or Chip Authentication confirms the chip is original.
- The user takes a live selfie, which is matched to the chip photo with liveness detection.
- If all checks pass, the identity is verified; if not, the case is flagged for review.
For additional security, all verification data can be reprocessed on backend servers to ensure integrity.
Current trends shaping eIDV
Electronic identity verification is rapidly becoming a foundational technology across industries.
Digital Travel Credentials
ICAO is actively piloting Digital Travel Credentials as complements, and potential successors to physical passports. Early DTC types allow travelers to create digital passport copies, while future iterations aim for fully digital credentials. While promising, widespread passportless travel remains a longer-term prospect.
Digital IDs and digital identity wallets
Digital identity adoption is accelerating globally. Regulatory initiatives in Europe, the United States, and other regions are driving the rollout of official digital identity wallets that allow individuals to store and share verified credentials securely.
For businesses, this shift means identity verification will increasingly rely on cryptographic validation rather than physical document inspection.
Identity proofing standards and guidelines
Updated digital identity guidelines increasingly emphasize multi-layered verification approaches. Rather than relying on a single factor, best practices recommend combining document authentication with biometric verification, especially in remote scenarios, to achieve higher assurance levels.
The future of electronic identity verification
As digital identity ecosystems expand, electronic identity verification is becoming a core building block of secure digital services. The continued rollout of digital IDs, mobile credentials, and cryptographically protected documents will further reduce reliance on manual checks.
Organizations that adopt robust eIDV frameworks today will be better positioned to support secure onboarding, regulatory compliance, and user trust in the years ahead.
Electronic identity verification is no longer a future concept; it is the foundation of digital trust.
