e-ID: How Electronic Identification Is Transforming Digital Access Across Public and Private Services

An e-ID (electronic identification) is a secure, government-backed digital identity that allows citizens to prove who they are online. The application process for obtaining an e-ID typically involves downloading an app, starting the application, selecting personal attributes, and completing verification steps. Instead of relying on physical documents, passwords, or manual verification, an e-ID enables individuals to authenticate themselves across services using a trusted digital identity system.

Countries across the world — including those in the European Union — use e-ID systems to give citizens faster, safer access to both public and private services. Computers and similar devices play a crucial role in storing, processing, and authenticating electronic IDs, whether through smartcards, mobile SIM cards, or biometric modules. The focus is on strong authentication and reducing administrative complexity.

e-ID is a form of digital identity that stores verified information about a person such as name, birth date, citizenship, or address. Digital identities are created during the enrollment or issuance process, where personal data is securely registered and verified. This digital identity can be used to sign documents, log in to online portals, and verify identity electronically.

Digital identity systems simplify how users prove who they are when accessing important services such as health care, banking, education, and employment portals.

One of the biggest benefits of e-ID is streamlined access to government services. Citizens can complete tasks online that traditionally required in-person visits, including:

In many countries, a valid residence permit or identity card is required to apply for and verify an e-ID, enabling access to government services.

This reduces administrative burden and improves efficiency for both citizens and public authorities.

Electronic identification uses secure authentication mechanisms — such as PIN codes, biometrics, and digital certificates — to verify identity online.
It replaces outdated methods like handwritten signatures and paper documents, enabling a faster and more secure digital experience. Many countries rely on smart cards, SIM-based authentication, or mobile identity apps to support e-ID usage.

The term electronic identity describes the digital representation of an individual in the e-ID system. It combines verified identity attributes with secure credentials, allowing citizens to interact with organizations and digital platforms in a trusted way. Various organizations, including businesses and public authorities, can issue digital credentials through e-ID platforms.

Electronic identity also supports electronic signatures, enabling citizens to legally sign contracts, submit applications, or authorize payments online.

In many regions, e-ID is embedded into a national ID card, enabling contact or contactless verification using a card reader or mobile device. Countries which currently issue government-issued eIDs include Afghanistan, Bangladesh, Belgium, Bulgaria, Chile, Estonia, Finland, Guatemala, Germany, Iceland, India, Indonesia, Israel, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Nigeria, Morocco, Pakistan, Peru, Portugal, Poland, Romania, Saudi Arabia, Spain, Slovakia, Malta, and Mauritius. Belgium has been issuing eIDs since 2003, and all identity cards issued since 2004 have been electronic. In Sweden, the most widespread electronic identification is issued by banks and is called BankID. Norway also issues electronic identity cards through banks, known as BankID. In Switzerland, the e-ID serves as the digital form of an ID card. In Austria, the Handy-Signatur and the Bürgerkarte (Citizen Card) have been upgraded and replaced by ‘ID Austria’ as of December 2023.

In some countries, the national health insurance card also functions as an electronic identification card, enabling secure access to healthcare and other digital services.

The European Union has been a global leader in digital identity through initiatives like the eIDAS Regulation, which sets standards for secure digital identification and trust services across member states.

The European Commission is also rolling out the EU Digital Identity Wallet, a cross-border system allowing citizens to store and use identity data, credentials, and official documents securely on their mobile devices. Germany introduced its electronic identity cards, called Personalausweis, in 2010.

e-ID simplifies how users interact with public services, supporting online access to education systems, health portals, tax authorities, and immigration offices.

Instead of relying on passwords or physical visits, citizens authenticate with their e-ID to retrieve documents, prove identity, or complete applications online. Additionally, electronic IDs can be used to verify age when purchasing age-restricted products.

e-ID systems can also provide proof of specific attributes, such as age or existence, while maintaining user privacy and minimizing the disclosure of unnecessary personal data.

The growth of e-government depends on digital identity. e-ID enables governments to modernize their infrastructure, reduce paperwork, improve service delivery, and secure sensitive information.

e-ID is a foundational part of future digital governance. Furthermore, electronic IDs can be used to order an extract from the criminal record, to prove a minimum age when purchasing age-restricted products, to register in the organ and tissue donation register, to subscribe to mobile plans, or even to order an electronic driving licence.

As electronic identification (eID) becomes the gateway to a wide range of public and private services, security and data protection are more important than ever. One of the main concerns with eID systems is the risk of data breaches, which could expose sensitive identity information. To address this, modern eID solutions are built with advanced security features such as encryption, secure data storage, and multi-factor authentication. Users are given greater control over their identity data, deciding which services can access specific information and for what purpose. For example, some systems use decentralized data storage linked directly to a user’s smartphone, making it nearly impossible to duplicate or misuse the e-ID.

The European Union’s strict data protection regulations, including GDPR, set a high standard for how personal data is managed and shared in electronic identification systems. By prioritizing user consent and robust security measures, eID systems help ensure that individuals can access services with confidence, knowing their identity and data are protected.

The rise of electronic identification (eID) is opening up new opportunities for businesses across sectors. By integrating eID into their processes, companies can significantly reduce the administrative burden of verifying customer identities, whether for opening a bank account, signing contracts online, or checking age for restricted services. This not only streamlines onboarding and reduces paperwork, but also helps businesses comply with regulations like KYC and AML. For example, a telecom provider can use eID to verify a customer’s identity instantly when issuing a SIM card, while a bank can allow customers to open accounts or sign loan agreements online without the need for physical documentation. The ability to verify identities electronically also helps prevent fraud, saving money and resources. By adopting eID, businesses can create more efficient, secure, and user-friendly experiences, ultimately driving growth and building trust with their customers.

The future of digital identity is set to be shaped by ongoing innovation in electronic identification (eID) systems. As technology advances, we can expect to see greater use of biometric authentication — such as facial recognition and fingerprint scanning — to verify identity online, making access to public and private services even more secure and convenient. Artificial intelligence and machine learning will further enhance the ability to detect fraud and streamline the verification process.

The European Union is leading the way with plans for a unified European Digital Identity framework, which will make it easier for citizens to use their eID across borders and access a wide range of digital services, from healthcare and education to banking and government applications. For example, patients will be able to securely access their medical records online, while students can verify their identity for remote learning platforms. As eID adoption grows, new services and applications will emerge, increasing efficiency and security across sectors and creating a more connected digital society for the future.
