Which Industry Sectors MUST Use Electronic Signatures?

Certain industries have a necessity to protect confidential information as well as a requirement for authentication - proving that a document was sent by a particular person. In this blog post, we will not be looking at why specific industry sectors SHOULD use electronic signatures, instead, we aim to educate the reader on where and why certain sectors NEED to use them.

Every industry is looking for methods to optimize its workflow operations, make savings, and decrease waste. Investing in electronic signatures is a safe and cost-effective approach to accomplish the aforementioned. Furthermore, any sector that receives documents in a digital form will also require the necessary software to view, manage and access documents, and preferably, all in one place.

Back to Basics

Digital Signatures for DummiesElectronic signatures have become fairly standard for individuals in many online transactions. For example, signing a document, applying for an online bank account, submitting an electronic tax return, or signing an employment contract. Digital documents contain crucial metadata that can include additional information about the transaction - who signed, the date, and the location. As a result, all of this information contributes to creating a concise digital audit trail, which enhances operations and streamlines costs through reduced human error and a paperless operation, whilst ensuring that client data is safeguarded and secure.

A signature policy is a set of rules for the creation and validation of an electronic signature, under which the signature can be determined to be valid. A given legal/ contractual context may recognize a particular signature policy as meeting its requirements. The signature policy may be explicitly identified or may be implied by the semantics of the data being signed and/ or other external data, like a contract being referenced which itself refers to a signature policy, as well as by the signing context. An explicit signature policy for open usage has a globally unique reference, which is bound to an electronic signature by the signer as part of the signature calculation.

Here we detail three main eSignature standards;

eSignature Standard


Advanced (AES)

Qualified (QES)

Transaction Risk





These are the most general and basic forms of electronic signatures which covers the broad spectrum of all electronic signatures.

Simple eSignatures do not need any form of identification verification from the signer, and the individual receiving the document is responsible for having trust in these signatures.

Advanced Electronic Signatures signatures, unlike simple electronic signatures, require a level of identification verification. They are based on certificates that uniquely link the eSignature to the document or transaction through a series of authentication processes that give it legitimacy and validity. 

Qualified Electronic Signatures are similar to advanced electronic signature standards.

The regulation requires a qualified certificate stored on a qualified signature creation device and must be issued and managed by a QTSP (Qualified Trust Service Provider), and it attests to the authenticity of the electronic signature to serve as proof of the signatory.

Typical Uses

Standard contracts and agreements, all general consent forms

Agreements, legal documents, online bank data and funds transfers

Commercial and residency transactions, calls for tender, business documents


The Qualified Electronic Signature (QES) is the most complete and secure method to digitally prove the identity of a subject and the acceptance of the content of a document.

This qualified electronic signature certificate comprises of an electronic document that links the signer's data and the validation of the QES signature to the irrefutable identification of the subject. 

The qualified certificate means that the qualified electronic signature would not require any form of expert evidence in a court of law in the event of a dispute since it is considered a piece of totally valid evidence with the highest level of legitimacy, originality and inviolability required.

Why These Industries Must Use Electronic Signatures

The following use cases are prime examples and not exhaustive lists:

Banking & Financial Services

  • Online banking - a typical use case is the signature of bank transfers via banking apps where the user’s private key is required to sign the transfer 
  • To digitally sign legally binding transactions from a PC or online device from remote locations, such as bank account openings, loan applications and mortgage services
  • To fulfill the requirement to protect personal data in the form of account numbers, PIN numbers and passwords

Insurance Sector

  • To apply for various types of insurance online
  • To enable swift and streamlined renewal of contracts and coverage
  • Electronic contracts detail accurate information. This means that claims can easily be verified and customers can be held for breach of contract in certain cases
  • Provides the option to electronically report a claim which also involves a signature and timestamp


  • To streamline business-to-business transactions where contracts need to be signed. Geographical locations could vary from business to supplier and therefore, online contracts need to be completed using electronic signatures
  • Many online transactions are considered to be ‘contracts’ upon completion of the transaction, therefore authentication and security are paramount

eInvoicing & Compliance with the EU VAT Directive


  • Various privacy laws protect personal information. Laws concerning the processing, storage and privacy of sensitive data need to be met at all times
  • Provides electronic signing of contracts for patients, vendors, employees, physicians, and other third-party organizations
  • Insurance claims that are health-related - an electronic signature software system would ensure that claims payouts are streamlined 

The Legal Industry

  • Fulfilling contracts and agreements. Delays are avoided as timescales are streamlined. Furthermore, legal documents are constantly revised, and therefore, revisions and signatures can be made remotely and with minimal effort
  • In a court of law, contractual evidence cannot be rescinded when proved that a certain person has electronically signed the contract.

The Retail Industry

  • Online and instore purchases, payments across suppliers, vendors, and employees
  • Securing card payments across the payment network across the flow of components that include the cardholder, the merchant (the store, restaurant etc), the issuer (the bank that issues the card), and the acquirer (that provides the tools to process card transactions).

Government Sectors

  • Public services - provision of electronic applications and payments for government services ranging from housing agreements through to waste disposal
  • Submitting declarations to government (which needs to be signed by mandated person)
  • The option to electronic sign internal agreements
  • The ability to electronically sign third-party contractual agreements, examples being, building work and materials, electricians and plumbers
  • ID- electronic passports, for example.

Property & Conveyancing

  • Registration of transfer deeds or other forms of dispositionary deeds can be electronically signed as a Qualified electronic signature is deemed legally identical to a wet signature.

Accountancy and Tax

  • The ability to complete online tax returns where the tax declaration is signed locally by the taxpayer/ account holder
  • To fulfill employee contracts
  • Remote signing of contracting agreements.


910/2014 European Union Regulation regarding electronic identification and trust services, known as eIDAS (electronic IDentification, Authentication and trust Services), describes the different types of electronic signature. 

eIDAS regulations prohibits EU member states from requiring a higher-level signature – there is no higher form of digital signature than the QES qualified digital signature. (Specified in eIDAS Article 27).

It is apparent that by employing remote QES to streamline business processes will benefit multiple industry sectors. In other circumstances as described above, there are numerous use cases where it is a ‘MUST HAVE’ rather than ‘a nice to have’ if a business intends to remain competitive in the age of digital transformation.
