Automatic immobiliser activation in leased cars, if an instalment has not been paid? International bank transfers credited to the recipient’s account within seconds? Sounds like science fiction? Yes, but blockchain has brought us one step closer to this vision. With many banks now considering blockchain as a viable solution due to its potential to speed up transactions, increase security and transparency, Bertrand Lavayssiere, managing partner at international financial management consultancy, zeb, explores the application of blockchain in retail banking in the fields of identity management, contract management and payment services** ![Bertrand Lavayssiere](https://prod.superblogcdn.com/site_cuid_cm5qst7v3003gwirgwqtxn8i8/images/bertrand-lavayssiere-1736842929151-compressed.jpg) Bertrand Lavayssiere **Identity Management** Authenticating customer identities is a frequent task in the relationship between [banks](https://www.financedigest.com/how-close-can-banks-get-to-their-customers.html "How close can banks get to their customers?") and their customers and requires considerable efforts from both sides. Know Your Customer principles and [anti-money laundering](https://www.financedigest.com/are-compliance-and-anti-money-laundering-aml-regulations-hurting-your-sales.html "Are compliance and anti-money laundering (AML) regulations hurting your sales?") standards do not only require ID checks of new customers but also frequently involve a substantial review of business relations. Different solutions are currently used including a manual check by bank clerks, mailing copies of IDs as well as modern processes like video chat via IDnow or WebID. However, none of these solutions are ideal for banks or customers. When opening a new account, customers need to restart such a procedure from scratch and a prior authentication, e.g. from other banks, cannot be reused. This is where the immutability of blockchains comes into play. In art trade, identity checks are used to allow collectors to verify the [authenticity of a work](https://www.financedigest.com/get-real-how-to-be-your-authentic-self-at-work.html "Get real: How to be your authentic self at work") of art quickly and efficiently. In the [digital world](https://www.financedigest.com/six-reasons-why-digital-world-classtm-finance-organizations-outperform-peers.html "Six Reasons Why Digital World ClassTM Finance Organizations Outperform Peers"), these solutions work like a digital signature. In the trade of physical works of art, [technologies use a special watermark to either prove the authenticity of a work](https://www.financedigest.com/what-is-5g-technology-and-how-it-works.html "What is 5G technology and how it works") of art or the complete documentation of all transactions. The latter depends on authorised parties entitled to verify the authenticity of a work of art and the consistent use of technology for all resales. Its application can be expanded to the [banking sector](https://www.financedigest.com/is-automation-key-to-esg-success-in-the-banking-and-finance-sector.html "Is automation key to ESG success in the banking and finance sector?") and the following scenario might soon become reality: _A customer verifies their [personal data](https://www.financedigest.com/data-privacy-and-navigation-how-our-personal-data-is-used-in-navigation-apps.html "Data Privacy and Navigation: How our personal data is used in Navigation Apps.") with an authorised party. This could include banks, public authorities or specialised companies, for example. From now on, this [data can be checked by all members of the blockchain using a public/private key process](https://www.financedigest.com/crowdsourcing-of-data-to-drive-the-high-throughput-process-development-market.html "Crowdsourcing of data to drive the High Throughput Process Development Market"). This enables the customer to open a new [bank account](https://www.financedigest.com/now-is-the-time-for-banks-to-introduce-intelligent-account-analysis.html "Now Is the Time for Banks to Introduce Intelligent Account Analysis") without filling out endless KYC questionnaires or to sign their tax declaration at the “online tax office”._ This procedure is not only convenient for customers, it also facilitates processes for banks by completely [automating onboarding processes and even allowing partial automation](https://www.financedigest.com/the-implantable-biomaterials-market-to-move-ahead-on-rpa-robotic-process-automation.html "The Implantable Biomaterials Market to move ahead on RPA (Robotic Process Automation)") to perform in-depth authentications more quickly. The FATCA (Foreign Account Tax Compliance Act) authentication of customers for US tax obligations can also be simplified. In particular, a legally compliant procedure approved by US authorities would significantly facilitate the authentication process for banks, which would make it highly appealing. The use of blockchain in identity management is not limited to the onboarding process but can be applied to additional [services in the course of the customer relationship—the previously mentioned identity verification](https://www.financedigest.com/how-digital-identity-verification-will-revolutionize-security-defenses-in-the-financial-services-industry.html "How Digital Identity Verification Will Revolutionize Security Defenses in the Financial Services Industry") can replace a signature. **Contract management** The second broad field of application for blockchain in [retail banking](https://www.financedigest.com/transforming-the-retail-banking-ecosystem-its-all-about-technological-innovation.html "TRANSFORMING THE RETAIL BANKING ECOSYSTEM: IT’S ALL ABOUT TECHNOLOGICAL INNOVATION") is concluding contracts. The blockchain is not limited to storing information such as the account balance or date of birth but can also store functions. In a nutshell, key components of contracts can be automatically activated. The following example shows the numerous [application areas](https://www.financedigest.com/high-barrier-packaging-films-for-pharmaceuticals-market-set-for-5-cagr-through-2029-blisters-remain-top-application-area-says-a-new-fmi-report.html "High Barrier Packaging Films for Pharmaceuticals Market Set for 5% CAGR Through 2029; Blisters Remain Top Application Area, Says a New FMI Report") of these “smart contracts”: _A customer takes out a consumer loan to purchase an entertainment system. Full access to the system is granted as long as the [customer pays](https://www.financedigest.com/uks-nationwide-to-pay-340-million-pounds-to-customers-after-profit-leap.html "UK’s Nationwide to pay 340 million pounds to customers after profit leap") the instalments. If an instalment payment is missed, the [screen will turn](https://www.financedigest.com/from-chasing-deals-to-turning-off-screens-cineworld-on-the-brink.html "From chasing deals to turning off screens: Cineworld on the brink") blank._ This idea can be developed further and expanded to other [bank products such as car or construction financing](https://www.financedigest.com/how-is-green-finance-reshaping-the-banking-industry.html "How is green finance reshaping the banking industry?"). In particular, the combination with the internet of things provides major opportunities for [banks to assert their contractual rights without the need for a collection agency or legal proceedings](https://www.financedigest.com/sse-and-equinor-to-proceed-with-4-billion-dogger-bank-c-offshore-wind-farm.html "SSE and Equinor to proceed with billion Dogger Bank C offshore wind farm"). If customers agree to such a contract, they can be offered more favourable terms. A similar concept exists for insurance customers who can pay reduced premiums if they share fitness and [activity data](https://www.financedigest.com/oil-slips-on-china-covid-curbs-weak-factory-activity-data.html "Oil slips on China COVID curbs, weak factory activity data") with their insurance. Current legislation, however, does not include smart [contracts yet and a changed](https://www.financedigest.com/pharmaceutical-contract-packaging-market-current-impact-to-make-big-changes-2020.html "Pharmaceutical Contract Packaging Market Current Impact to Make Big Changes 2020") legal situation may throw a spanner into the works. Smart contracts are not only a blessing for banks. They might also directly affect their business model. With smart contracts, [retail customers will be able to agree on financing directly with the seller when buying a car or home and forcing banks](https://www.financedigest.com/how-effective-talent-management-could-disrupt-the-retail-banking-sector.html "HOW EFFECTIVE TALENT MANAGEMENT COULD DISRUPT THE RETAIL BANKING SECTOR") into the role of the passive onlooker. [P2P lending](https://www.financedigest.com/peer-to-peer-lending-how-to-use-p2p-lending-for-loans-and-investments.html "Peer-to-Peer Lending: How to Use P2P Lending for Loans and Investments") takes a similar line: currently still requiring a bank in the background, smart contracts might make them redundant in the future. This is a direct attack on the core business of a [retail bank](https://www.financedigest.com/insight-into-tomorrows-retail-banking-customers.html "INSIGHT INTO TOMORROW’S RETAIL BANKING CUSTOMERS"). **Payment transactions** The [third field of application directly interferes with payment](https://www.financedigest.com/polands-bank-millennium-third-quarter-results-hit-by-payment-holidays.html "Poland’s Bank Millennium third-quarter results hit by payment holidays") transactions. [Blockchain can simplify and accelerate international payment](https://www.financedigest.com/three-ways-blockchain-is-transforming-payments.html "Three ways blockchain is transforming payments") transactions, in particular. At the moment, international transfers still take several days and involve high fees whereas with [blockchain technology](https://www.financedigest.com/how-blockchain-technology-can-help-the-fashion-industry-make-verifiable-green-claims.html "How Blockchain Technology Can Help the Fashion Industry Make Verifiable Green Claims"), they can be realised almost instantly and at minimal transaction costs. Payment transaction products based on blockchain, such as Ripple, have the potential to replace centralised systems like SWIFT and to jeopardise the business model of the small number of [large banks](https://www.financedigest.com/swiss-national-bank-makes-another-large-draw-on-fed-swap-line.html "Swiss National Bank makes another large draw on Fed swap line") in the area of cash management. In this context, Ripple is the [system currently](https://www.financedigest.com/ventricular-restoration-systems-market-development-history-current-scenario-industry-insights-2030.html "Ventricular Restoration Systems Market Development History, Current Scenario & Industry Insights 2030") used in practice (e.g. by Santander) and works as follows: _Customer A authorises their gateway (e.g. the bank) to [transfer a certain amount to Customer](https://www.financedigest.com/natwest-limits-customers-crypto-transfers-citing-scam-concerns.html "NatWest limits customers’ crypto transfers, citing scam concerns") B. An algorithm is used to find the shortest path between the customers’ gateways and completes the transaction after the next blockchain update._ Another use of blockchain in payment transactions is bitcoin. Even though the currency has been quite popular for a while, [bitcoin is not expected to replace the common currency](https://www.financedigest.com/bitcoin-sterling-volumes-spike-to-record-high-as-british-currency-flounders.html "Bitcoin-sterling volumes spike to record high as British currency flounders") system.  However, it is very likely that [bitcoin will be established as the standard](https://www.financedigest.com/bitcoin-could-hit-100000-by-end-2024-standard-chartered-says.html "Bitcoin could hit 0,000 by end-2024, Standard Chartered says") currency for certain purposes. [Bitcoin or other crypto](https://www.financedigest.com/low-carbon-bitcoin-crypto-miners-green-power-talk-angers-texas-locals.html "Low-carbon bitcoin? Crypto miners’ green power talk angers Texas locals") currencies can currently be obtained or managed by wallet services. Wallet [services are not always easy to use and sometimes not particularly secure](https://www.financedigest.com/a-culture-of-cyber-security-throughout-financial-services-organisations.html "A Culture of Cyber Security Throughout Financial Services Organisations") as a number of hacker attacks have revealed. Banks as managers and [payment processors of crypto](https://www.financedigest.com/why-are-companies-implementing-crypto-payments.html "Why are companies implementing crypto payments?") currencies can tap into new business segments and use the public trust and their secure and efficient IT systems to compete with other providers. It [remains to be seen if and how soon blockchain will succeed in retail banking](https://www.financedigest.com/bank-of-england-consults-on-remaining-basel-bank-capital-rules.html "Bank of England consults on remaining Basel bank capital rules"). As with any technology depending on networks, its usability and security depend on the number of users. Santander with Ripple as well as bitcoin prove nevertheless that there is a [demand for applications using blockchain technology](https://www.financedigest.com/computer-assisted-anesthesia-systems-market-industry-analysis-opportunities-technology-demand-top-players-and-growth-forecast-2027.html "Computer Assisted Anesthesia Systems Market Industry Analysis, Opportunities, Technology, Demand, Top Players and Growth Forecast 2027"). --- This blog is powered by Superblog.
