The dilemma of digital wallets: convenience vs. security
Digital wallets, with their promise of quick and secure payments, have gained increasing popularity worldwide. However, as these technologies advance, questions arise regarding their security and consumer trust.
The growing adoption of digital payment wallets
F
actors such as convenience, speed, and integration with smartphones have driven the uptake of digital wallets, particularly among younger generations, as described in a study published last July focusing on the US market.
The data shows that American consumers are increasingly willing to abandon cash and physical cards in favour of digital solutions. The 2020 crisis accelerated this trend by encouraging contactless payments. Additionally, the proliferation of mobile banking apps and the provision of financial services by non-traditional companies have contributed to this paradigm shift.
According to the same report, 71% of citizens would not face significant issues in transitioning to a cashless society. The segment aged between 18 and 34 is the most inclined to digitalise their daily lives, showing a greater preference for non-traditional banking compared to older generations.
However, market penetration in the US still lags behind countries like the UK and Australia, suggesting considerable room for growth.
Identity theft and fraud: the dark side of digital wallets
Digital wallets are projected to reach an astonishing 5 billion users worldwide by 2026. However, another study conducted by researchers from the Universities of Pennsylvania and Massachusetts raises concerns about certain security aspects, warning that changes in authentication methods are needed to prevent identity theft and fraud.
The study suggests that banks should enforce uniform policies regarding authentication systems. Delegating these methods to digital wallets creates security gaps that can be exploited by cybercriminals, according to this research.
The severe consequences of such attacks are well known: identity theft, unauthorised access to bank accounts, and fraudulent transactions. The researchers warn that criminals can exploit vulnerabilities in authentication systems to make purchases with stolen cards, even if the banks have blocked them.
Overcoming challenges to unlock the potential of digital wallets
Digital wallets, both for payments and identity, offer a wide range of possibilities beyond traditional monetary transactions. Their potential to transform how we interact with both the digital and physical worlds is immense. As we have seen, it is crucial for them to actively collaborate with merchants and banks to identify needs and vulnerabilities, and from there, to leverage their capabilities. For instance:
- Micropayments: The ease and speed of transactions through digital wallets have paved the way for micropayments, enabling low-value transactions to be carried out simply and efficiently.
- Integration with loyalty programs: Another option is for these wallets to become central to loyalty programmes, allowing consumers to accumulate points, redeem rewards, and access personalised offers more easily and quickly. This fosters customer loyalty and provides businesses with valuable data on consumer habits. However, best practices should always prioritise user privacy and minimise the amount of data collected.
Identity Wallets: the SSI Model as a safeguard for rights and freedoms
Digital identity wallets, designed to securely store verifiable personal attributes, are set to play a crucial role in transforming how individuals interact with both public and private services. However, not all approaches are created equal, and the Self-Sovereign Identity (SSI) model stands out as the one that best protects citizens’ fundamental rights and freedoms.
From verification to digital empowerment
Beyond facilitating identity verification, the SSI model gives individuals full control over their personal information. Instead of relying on centralized third parties that collect, store, and share data without sufficient transparency, SSI allows users themselves to decide which attributes to share, with whom, for how long, and for what purpose.
This decentralized architecture, based on verifiable credentials and cryptographic proofs, reinforces key principles such as:
- Privacy by design: data is shared only when necessary and in a minimized form.
- Consent: users can grant or revoke permissions with ease.
- Portability and autonomy: a citizen’s identity is not tied to any single platform or provider.
Practical applications with democratic safeguards
By adopting SSI as a foundation, identity wallets can enable a digital ecosystem that is fairer, more transparent, and more resilient. Key examples include:
- Streamlined procedures and services: opening a bank account, applying for benefits, or accessing healthcare can be done smoothly and without unnecessary bureaucracy—while retaining sovereignty over one’s own data.
- Cross-service authentication without silos: the same set of credentials can be used across multiple services, both public and private, without replicating records or relying on centralized intermediaries.
- Innovations like secure electronic voting: ensuring anonymity, integrity, and verifiability through cryptographic proofs and decentralized traceability.
A defense against abuse and surveillance
In an era of growing concern over mass surveillance, commercial data exploitation, and opaque uses of artificial intelligence, the SSI model emerges as both a technological and legal counterbalance. By returning identity control to individuals, it limits the power of centralized platforms and supports a more balanced ecosystem—one aligned with democratic principles and fundamental rights enshrined in constitutions and international charters.
It is essential that companies developing and deploying these technologies prioritize user privacy and collect and use only the data strictly necessary for each service. Only then can we fully harness the growth projected by experts without putting users at risk. In the digital world, trust is the most valuable asset.
