2.1	Digitalization and Transaction Banking
The advent of the digital revolution has brought about a significant transformation in the operational landscape of businesses, including the banking sector. The incorporation of digital technologies into diverse facets of business operations, commonly referred to as digitalization, has emerged as a crucial element for enhancing growth and competitiveness in contemporary banking, as per Haddad's (2018) definition. The exploration and implementation of innovative digital solutions by banks in the UK to improve their transaction banking services necessitates an examination of the effects of digitalization on banks' performance and customer satisfaction. The objective of this literature review is to furnish a thorough examination of the impact of digitalization on transaction banking within the United Kingdom. The analysis will concentrate on four key areas, namely efficiency and productivity, customer experience and satisfaction, innovation, and risk management. Moreover, the present review will analyse the obstacles, difficulties, and prospective developments that could influence the trajectory of digital transaction banking in the United Kingdom.
The term digitalization pertains to the conversion of analogue data into digital form and the integration of digital technologies into diverse facets of an enterprise's activities (Gartner, 2019). The banking industry has embraced digitalization, which involves the incorporation and utilisation of Information Communications Technology (ICT) to optimise transaction banking procedures, augment customer service provision, and stimulate business expansion (Mishra et al., 2017). The advent of novel technologies has prompted banks to adopt digitalization as a means of bolstering their operations, enhancing productivity, and fortifying their competitive advantage.
Transaction banking is a distinct subset of the financial services industry that concentrates on furnishing banking amenities to expedite financial transactions among individuals or entities. The range of services offered may encompass cash management, trade finance, securities settlement, and payment schemes, as per McKinsey & Company (2021). Transaction banking is a crucial component of the worldwide commercial system, serving as a fundamental support for the daily financial operations of the banking industry in the United Kingdom. The digitalization of traditional transaction banking services has resulted in significant transformation, as banks endeavour to cater to the changing requirements of their customers in a swiftly evolving banking environment (Frazier-Logue & Datta, 2018).

2.2	Key Authors and Theories on Digitalization and Banking
In recent years, several authors have made significant contributions to the understanding of digitalization in the banking sector. One of the prominent scholars in the field of digitalization and banking is Brett King, who authored the book, “Bank 3.0: Why Banking is No Longer Somewhere You Go But Something You Do” (King, 2012).

2.3	The Rise of Digitalization in Banking
The rise of digitalization in banking can be traced to the increasing dependence on technology across various sectors of the global economy. One of the earliest technological advancements in banking started with the advent of the automated teller machine (ATM) in the 1960s, which allowed customers to withdraw cash without the need for human intervention (Bátiz-Lazo, 2018). This landmark innovation paved the way for subsequent digital developments in the banking sector, transforming transaction banking and improving the customer experience.
As the internet gained prominence in the 1990s, the first instances of online banking emerged, providing customers with access to their bank accounts through electronic channels (Zagalaz-Garca et al., 2015). The availability of online banking significantly reduced the need for physical branches and paved the way for further advancements in digitalization. Over time, banks began to offer more sophisticated services online, such as secure money transfers, electronic bill pay, and balance inquiries, among others.
With the growth of mobile technology and the widespread adoption of smartphones, mobile banking rapidly became the next frontier of digitalization in the banking sector (Shaikh & Karjaluoto, 2015). Mobile applications allowed banks to offer comprehensive banking services accessible anytime, anywhere. Customers experienced increased convenience and control over their finances, enabling transactions, account management, and financial planning, all executed with just a few taps on their mobile devices (Datta, 2018).
As financial technology (FinTech) companies emerged, they challenged traditional banking models with innovative platforms and services, further accelerating the pace of digitalization in the banking sector (Arner et al., 2016). FinTech firms have introduced new payment modes, peer-to-peer lending, and robo-advisory services, which have compelled banks to reconsider their strategies and adopt new technologies to stay competitive (Boillat & Legner, 2015).
Recent trends in digitalization, such as artificial intelligence, blockchain, and big data analytics, also have the potential to revolutionise the banking sector (Miles, 2019). Banks are increasingly leveraging these technologies to enhance efficiency, reduce costs, and manage risks more effectively (Kauffman et al., 2015). Furthermore, the rise of open banking initiatives, which promote collaboration between banks and FinTech firms, facilitates the creation of innovative products and services designed to meet evolving customer needs (Dorfleitner et al., 2021).

2.5	Impacts of Digitalization on Transaction Banking
2.5.1	Efficiency and Productivity
Digitalization has significantly impacted transaction banking, leading to increased efficiency and productivity in processes and services. Advancements in information and communication technology (ICT) have played a crucial role in the transformation of the banking sector, improving service delivery and supporting risk management (Ozili, 2018). The introduction of new digital banking services and platforms, such as mobile banking and online banking, has streamlined banking processes, reduced transaction times, and improved overall service quality (Jumaev & Hanaysha, 2019).
The automation of banking processes and the use of artificial intelligence (AI) and machine learning technologies has further enhanced productivity in the transaction banking space (Huang & Chiu, 2018). According to Accenture (2019), digitalization enables banks to optimize their operations, resulting in an estimated 20-40% reduction in operational costs. Moreover, by investing in digital infrastructure, banks can handle a higher volume of transactions, ultimately leading to increased profits (Boyd, Mooney & Hill, 2019).
Improved data management has also been a vital aspect of digitalization, allowing for better utilization and analysis of customer data, thereby enhancing banks’ ability to make informed decisions and optimize their operations (Mishra & Singh, 2018). Digitalization has accelerated the adoption of electronic payment systems, reducing the need for physical cash and checks, which in turn has resulted in faster transaction processing times and decreased fraud (Demirgüç-Kunt et al., 2018).
2.5.2	Customer Experience and Satisfaction
Digitalization has had a significant impact on customer experience and satisfaction, primarily by offering convenience, personalization, and accessibility to banking services (De Koker & Jentzsch, 2013). Internet banking and mobile banking platforms have made it easier for customers to access and manage their accounts, transfer funds, pay bills, and apply for loans, among other services, without needing to visit a physical branch (Shaikh & Karjaluoto, 2015).
Through the implementation of AI, chatbots, and other virtual assistants, banks can now provide personalized recommendations and responsive customer support, leading to increased satisfaction (Aker & Mbiti, 2010). Mobile banking applications, in particular, have been a game-changer in the industry, offering customers a convenient way to perform transactions on-the-go and enabling banks to engage with a wider customer base (Chibelushi, 2018).
Digitalization has also allowed banks to gain valuable insights into customer behavior through the analysis of data generated by digital banking activities (De Koker & Jentzsch, 2013). Banks can use this data to improve customer communication, offer personalized products and services, and enhance overall customer satisfaction (Mishra & Singh, 2018).
However, despite the numerous benefits of digital banking, it is important to recognize potential challenges, such as security concerns and privacy issues, which may affect customer satisfaction (Nguyen & Nguyen, 2018). Therefore, it is crucial for banks to invest in robust security measures and ensure data privacy to maintain customers’ trust in digital banking services (Van der Aalst et al., 2018).
2.5.3	Innovation and Competition
Digitalization has spurred a wave of innovation in the transaction banking industry. The development and adoption of new digital technologies, such as mobile banking applications, peer-to-peer payment platforms, and digital wallets, have created a highly competitive environment, as banks strive to attract and retain customers by offering a variety of digital banking services (Hawksworth & Jacobsen, 2019).
Innovations such as artificial intelligence (AI), machine learning, and data analytics have played a significant role in transforming the competitive landscape of transaction banking in the UK by enabling banks to offer personalized financial products and services tailored to individual customer needs (KPMG, 2019). For instance, AI and machine learning technologies are being used in credit scoring and risk assessment processes to provide more accurate and efficient lending decisions (Lukoianova & Rubin, 2019).
Furthermore, the rise of FinTech companies and non-bank players has heightened the competitive landscape of transaction banking, as these new entrants offer innovative financial solutions that may challenge traditional banking services (Ali et al., 2020). For example, peer-to-peer lending platforms have emerged, providing alternative financing options for individuals and businesses that may not qualify for traditional bank loans (Zetzsche et al., 2020).
As competition in the banking industry intensifies, banks must continue to innovate and enhance their digital offerings to remain relevant and maintain a competitive edge. However, the rapid pace of digital transformation and the perpetual need for innovation also present challenges for banks, as they must prioritise their investments in new technologies while remaining compliant with relevant regulations and security standards (Lopez-Claros et al., 2020).
2.5.4	Risk Management and Security
While digitalization has undoubtedly transformed transaction banking, it has also introduced new risks and security challenges for financial institutions. Cybersecurity risks, such as data breaches, phishing attacks, and malware infections, pose significant threats to the integrity of banks’ IT systems and may lead to substantial financial losses and reputational damages (KPMG, 2019).
Banks must invest in robust security measures to protect their customers’ personal and financial information from these cyber threats. This includes regular security audits, vulnerability assessments, and penetration testing, as well as the implementation of advanced security technologies, such as encryption, multi-factor authentication, and real-time fraud detection systems (Haworth & Kangatharan, 2019).
Another challenge that banks face in managing digital risk is the evolving regulatory landscape surrounding data privacy and consumer protection. The introduction of regulations such as the General Data Protection Regulation (GDPR) in the European Union has set new privacy standards that banks must adhere to when handling customer data (Bannister, 2018). Compliance with these regulations requires banks to implement strict data governance and risk management procedures, which can be complex and resource-intensive (Liébana-Cabanillas et al., 2020).
Moreover, the rapid pace of innovation in transaction banking implies that banks must continually update and adapt their risk management strategies to address emerging digital risks. This may involve collaborating with technology vendors, security experts, and industry regulators to share knowledge and best practices (Marshall et al., 2020).
2.5.5	Regulatory and Compliance Implications
Adoption and implementation of digital technologies in transaction banking can have a substantial effect on regulatory and compliance requirements. As the use of digital tools continues to increase, banks must adapt to evolving laws and regulations to ensure compliance, preserve customer confidence, and mitigate potential risks. With the advent of digitalization in transaction banking, there has been an increase in the number of regulatory bodies and compliance requirements imposed on banks to ensure that their operations remain compliant. As banks adopt digital technologies, they must also comply with regulations such as the General Data Protection Regulation (GDPR) to safeguard customer information and privacy (European Parliament, 2020). The Financial Conduct Authority (FCA) in the United Kingdom has also introduced various initiatives to monitor and regulate digital banking operations, including the establishment of the Regulatory Sandbox, which allows fintech firms to test new digital technologies in a controlled environment (FCA, 2020).
Data security and privacy are crucial concerns in digital banking transactions. Banks must maintain robust security measures to safeguard the personal and financial information of their customers (Prasad, Shankar, and Raghavan, 2020). This includes implementing advanced encryption technologies, multi-factor authentication, and continuous system monitoring (Ali et al., 2020). Compliance with GDPR requirements, such as obtaining customer consent for data processing and ensuring anonymization of data when required, is also essential. Banks must also maintain transparency in their data handling practises in order to build customer trust and comply with regulatory requirements (Moria, 2019).
As digitalization expands the range of services offered by banks, they must also modify their AML and CTF policies and procedures, as well as develop more effective risk management systems. Digital banking presents new opportunities for money laundering and terrorism financing, necessitating updated AML and CTF measures for detecting, preventing, and reporting suspicious activities (Bevilacqua, 2019). This may involve the implementation of advanced analytical tools and machine learning algorithms to monitor transactions, improve customer due diligence processes, and comply with regulations such as the EU's Fifth Anti-Money Laundering Directive (Europe, 2020).
In order to maintain relevance and efficacy as digital technologies continue to evolve, regulators must continually update and modify regulations and guidelines. This can make it difficult for banks to keep up with regulatory changes, ensure compliance, and maintain positive relationships with regulatory authorities. Banks must theefore develop agile compliance strategies to respond swiftly to changes in the regulatory landscape and invest in continuous professional development for employees to keep them abreast of new laws and best practises (Cummings, Babbage, & Zhou, 2021).

2.6	Barriers and Challenges of Digitalization in Transaction Banking
Although digitalization offers numerous benefits for transaction banking, banks must overcome significant obstacles and challenges to implement digital technologies effectively. These obstacles may stem from a variety of sources, such as technology adoption, regulatory compliance, and security concerns.
To start with, banks face difficulties in integrating new digital technologies with their existing infrastructure and processes (Beck et al., 2020). Incompatibility between legacy systems and new digital platforms may result in inefficiencies and siloed operations. Moreover, the rapid pace of technological advancements in the banking industry necessitates that banks continually update their systems, which can be expensive and time-consuming (Stulz, 2019). Incorporating new digital technologies may expose banking institutions to a skills gap, according to Kim et al. (2020). In order to successfully navigate the digital transformation, banks must invest in training current employees and recruiting new personnel with the necessary technological skills.
Also, the digitalization of transaction banking also poses regulatory difficulties (Basel Committee on Banking Supervision, 2018). To guarantee the stability, integrity, and efficacy of the financial system, financial institutions must adhere to stringent regulations. Digital innovations such as cryptocurrencies, peer-to-peer lending, and digital identity verification may present regulatory challenges, as existing rules may not be designed to accommodate these new forms of financial transactions (Philippon, 2016). Moreover, as digital transactions transcend national borders, international regulatory harmonisation is required to address issues such as data privacy and anti-money laundering measures (Buchak et al., 2018).
Furthermore, the increased reliance on digital platforms for transaction banking has also prompted concerns regarding the security of customer data and protection from cyber threats (Li et al., 2018). Banks must invest in robust security measures to prevent unauthorised access to sensitive customer data and financial systems as more transactions move online (Herath & Rao, 2017). Moreover, the increasing sophistication of cybercriminals poses a significant challenge for banks to continuously update their security infrastructure in order to stay ahead of new threats (Romanosky et al., 2019).
Despite the many advantages of digitalization in transaction banking, customer trust and acceptance of digital banking services continue to be a challenge (Roy et al., 2017). (Ho et al., 2019) Some customers may be hesitant to switch from traditional banking methods to digital channels due to privacy and security concerns or unfamiliarity with new technologies. Banks must improve customer education and awareness of digital banking services, as well as address any potential issues or concerns, in order to increase customer adoption and satisfaction (Hamari et al., 2015).

2.7	Future Trends and Opportunities in Digital Transaction Banking
The digital revolution in transaction banking is far from over. New technologies and trends continue to emerge, transforming the way banks operate and interact with their customers. Here, we see key future trends and opportunities in digital transaction banking that have the potential to shape the industry further and present possible challenges for banks, customers, and regulators alike.
Artificial Intelligence (AI) and Machine Learning: Advanced data analytics powered by AI and machine learning algorithms can revolutionize transaction banking by providing real-time insights into customer behavior and preferences. This can help banks offer more personalized services and better risk management. It also facilitates the automation of routine tasks, freeing up human resources for more complex decision-making processes (Chui et al., 2020). However, the increased reliance on AI and machine learning may raise ethical and regulatory concerns, such as data privacy and discrimination, which need to be addressed proactively.
Blockchain Technology: Blockchain, a decentralized and secure ledger system, has the potential to transform transaction banking by enabling faster and more efficient cross-border payments and verification processes. It can also improve transparency and reduce the risk of fraud in trade finance and syndicated loans (Mills et al., 2016). Despite its potential benefits, blockchain technology faces various challenges, including a lack of standardization, scalability, and interoperability with existing systems (Lee & Pilkington, 2017).
Open Banking and Application Programming Interfaces (APIs): Open banking, driven by regulations such as the European Union’s Revised Payment Services Directive (PSD2), requires banks to provide third-party service providers access to their customer data through APIs (Haddad & Hornuf, 2019). This encourages innovation and competition, enabling customers to benefit from a wider range of financial services. Banks will need to adapt to this new paradigm by developing robust, flexible, and secure API platforms (Hayes, 2018).
Digital Identity and Biometrics: Digital identity solutions and biometric authentication technologies can enhance transaction banking security and user experience. For example, customers can access their accounts using fingerprint or facial recognition, reducing the need for cumbersome passwords and security questions (Marr, 2018). Banks will have to consider possible privacy concerns and invest in secure and reliable identity management systems as these technologies become more prevalent.
Financial Inclusion and Mobile Banking: With the increasing ubiquity of smartphones, mobile banking has become an essential tool to promote financial inclusion, especially in developing countries (Demirguc-Kunt et al., 2018). Digital transaction banks need to ensure their services remain accessible to everyone, including those without access to traditional banking. This may involve partnering with telecommunication companies or developing innovative mobile banking solutions tailored to the needs of the unbanked population.
Cybersecurity and Regulatory Compliance: As transactions become increasingly digitized, banks continue to invest heavily in cybersecurity and data protection measures to safeguard customer information and comply with evolving regulatory requirements (Dorantes et al., 2019). This may involve adopting new technologies, implementing robust risk assessment frameworks, and ensuring consistent employee training to improve security awareness.
