In Brief (TL;DR)
Digital wallets like Apple Pay and Google Pay protect your sensitive data through a process called tokenization, which replaces your real card number with a unique code to secure every transaction.
Thanks to a process called tokenization, your real card numbers are never shared during payments, drastically reducing the risk of fraud.
The key to this security is tokenization, a process that replaces your card number with a unique digital code, or "token," for every purchase.

Paying for coffee with your watch, buying a train ticket by tapping your smartphone on the reader, shopping online without ever taking out your credit card. Actions that seemed like science fiction just a few years ago are now part of our daily lives. Digital wallets, like Apple Pay, Google Pay, and Samsung Pay, have turned our devices into smart wallets, making transactions faster and more convenient. But behind this simplicity lies a fundamental question: how safe is our money? The answer lies in a technology as powerful as it is invisible: tokenization.
This process is the heart of digital payment security. In a world where data breaches are increasingly common, tokenization acts as a shield, protecting our sensitive card information. Instead of transmitting the actual card number during a purchase, the system replaces it with a unique, random code called a “token.” This small adjustment completely changes the game, making any intercepted data useless to potential malicious actors. In this article, we’ll explore how this technology works, analyzing its impact in the Italian and European context—a market balanced between a historical preference for tradition and the push toward digital innovation.
The Era of Invisible Payments: What Are Digital Wallets
Digital wallets, or e-wallets, are software applications that allow you to securely store digital versions of your credit, debit, and prepaid cards on smartphones, smartwatches, or other devices. The most well-known names are Apple Pay, Google Pay, and Samsung Pay, which integrate seamlessly into their respective ecosystems. Their success is undeniable: in the first half of 2025, digital payments in Italy reached 236 billion euros, a 6% increase from the previous year. This figure highlights a cultural shift, where the convenience and efficiency of “invisible” payments are becoming the norm for millions of people.
These tools represent a bridge between the physical and digital worlds. They not only replace the plastic of cards but also the need to carry a bulky wallet. For Mediterranean culture, and particularly Italian culture, historically tied to the use of cash, this transition is not trivial. However, the growing adoption, also driven by the spread of contactless payments, shows a new openness to innovation, provided it guarantees a level of security perceived as solid and reliable. And this is where tokenization plays its crucial role.
The Secret to Security: What Is Tokenization?
Imagine leaving your coat at a theater’s coat check. In return, you get a numbered token. That token isn’t your coat, but it gives you the right to get it back. If you lost the token, whoever found it couldn’t do anything with it, because only the coat check staff knows which coat it corresponds to. Tokenization works in a very similar way: it replaces your sensitive card data, like the 16-digit number (PAN), with a “token,” which is a randomly generated string of characters.
Tokenization is a security technique that replaces sensitive payment information, such as credit card numbers, with a unique, random set of characters called a token.
When you add a card to a digital wallet, the real number is not saved on the device. Instead, it is sent securely to your card network (e.g., Visa, Mastercard), which stores it in a digital “token vault” and generates a device-specific token. During a payment, only this token is transmitted to the merchant’s POS terminal. Your card number remains protected, never exposed to risk. This mechanism makes fraud and credit card cloning extremely difficult, as the token is useless outside of its specific context.
How Tokenization Works in the Most Popular Wallets
Although the basic principle is the same, the main digital wallets implement tokenization with some specific features that define their security architecture. Understanding these differences helps to grasp the level of protection offered by each solution.
Apple Pay: The Digital Fortress
Apple has placed security at the core of its payment strategy. When a card is added to Apple Pay, the generated token (called a Device Account Number or DPAN) is stored in a dedicated hardware chip called the Secure Element (SE). This chip is a true physical safe, isolated from the device’s main operating system. Access to the token is only granted after biometric authentication (Face ID or Touch ID) or via the device’s passcode. Each transaction also generates a dynamic security code, similar to a CVV, which ensures its uniqueness. This combination of tokenization, hardware storage, and biometric authentication makes Apple Pay one of the most secure solutions on the market.
Google Pay: Flexibility and Security
Google Pay’s approach is slightly different, prioritizing flexibility across a wide range of Android devices. Instead of always relying on a hardware Secure Element (not present on all models), Google Pay uses a technology called Host Card Emulation (HCE). The tokens are managed primarily in the cloud and securely loaded onto the device. For each transaction, in addition to the token, a one-time cryptogram is generated to validate it. Even without a dedicated chip, security is ensured by multiple software layers and the requirement to unlock the device for payments above a certain threshold, offering an effective balance between accessibility and protection.
Samsung Pay: The Technology That Unites Past and Future
Samsung Pay stands out for its dual transmission technology. In addition to the common NFC (Near Field Communication), also used by Apple and Google, Samsung Pay supports MST (Magnetic Secure Transmission). This technology emulates the swipe of a card’s magnetic stripe, making the wallet compatible even with older POS terminals that don’t have a contactless reader. Despite this backward compatibility, security is not compromised. Even in MST transactions, the system transmits a token and not the actual card number, ensuring the same protection standards as NFC payments. This feature has allowed Samsung Pay to accelerate the adoption of mobile payments in markets with older infrastructure.
Italy and Mediterranean Culture: A Bridge Between Tradition and Innovation
Italy is undergoing a significant transition. While still ranking among the last in Europe for per capita transactions, the country shows a growth rate in digital payments that is above average. This indicates that initial skepticism, rooted in a culture that for decades has favored cash as a symbol of control and tangibility, is giving way to an awareness of the practical benefits of innovation. The pandemic certainly accelerated this process, but the trend is solidifying because users perceive real value.
Tokenization is a key factor in this dynamic of trust. Communicating that your card number is never shared with the merchant or stored on your smartphone directly addresses the main concern of Italians: the fear of fraud. In a context where online scams are a real threat, knowing that a robust technological shield exists encourages even the most cautious to give it a try. Security thus becomes not just a technical requirement, but a fundamental argument for overcoming cultural barriers, proving that innovation and tradition (understood as the need for safety and protection) can and must coexist. Protecting yourself from phenomena like phishing and smishing becomes easier when fundamental data is not exposed.
The Concrete Advantages of Tokenization for Everyday Life
Beyond the technical aspects, tokenization brings tangible and immediate benefits to the daily life of anyone using a digital wallet. These advantages go far beyond mere convenience.
- Superior security: If your smartphone is lost or stolen, no one can use your wallet without your fingerprint, your face, or your passcode. You can also remotely block the tokens without having to block your physical card, which remains usable.
- Enhanced privacy: The merchant you shop with never sees or stores your card details. This drastically reduces the risk of your information falling into the wrong hands in the event of a cyberattack on the store’s systems.
- Convenience without compromise: Tokenization allows you to combine the speed of contactless payments with a level of security comparable to that of a safe. You no longer have to choose between speed and protection.
- Fraud reduction: Stealing a token is almost always useless. It cannot be used for online purchases on other sites or to create a cloned card.
- Seamless shopping experience: In online stores and apps that support digital wallets, you can pay with a single click or tap, without having to enter your card details and shipping address every time, with the certainty that the transaction is protected.
Beyond Wallets: The Future of Tokenization
The impact of tokenization is not limited to smartphone payments. This technology is laying the groundwork for an even broader and more secure future for digital transactions. One example is the evolution of online shopping with solutions like Click to Pay, which apply the same security principles to eliminate the manual entry of card data on e-commerce sites. Recurring payments, such as subscriptions to streaming services or utilities, also benefit from tokenization: if your card expires, the token can be automatically updated by the network, preventing service interruptions.
Looking even further ahead, tokenization will extend to the Internet of Things (IoT). Imagine a refrigerator that orders milk when it’s running low or a car that autonomously pays for parking and electric charging. In these scenarios, each device can have its own token associated with a payment method, enabling secure and automatic transactions without human intervention. Tokenization, born to protect cards, is evolving into a fundamental pillar for the security of the entire digital economy.
Conclusions
Tokenization represents a quiet but fundamental revolution in the world of digital payments. It has transformed our smartphones and smartwatches into payment tools that are not only convenient but also extremely secure. By replacing the actual card number with a unique digital code, this technology creates a robust shield that protects consumers from fraud, effectively addressing the security concerns that often accompany technological innovation.
In the Italian and European context, where trust is a key element for the adoption of new financial habits, tokenization acts as a bridge. It allows us to embrace the modernity of digital wallets without sacrificing peace of mind, a value deeply rooted in our culture. Understanding how this mechanism works is not just a technical curiosity, but an essential step toward becoming more aware and secure users in an increasingly digitized world. The next time you pay with your phone, you’ll know that behind that simple gesture is a powerful technology working to protect your money.
Frequently Asked Questions
Tokenization is a security process that replaces your real credit or debit card number with a unique digital code, called a ‘token’. When you pay with wallets like Apple Pay or Google Pay, only this token is sent to the merchant, not your actual card data. If a malicious actor were to intercept the token, they couldn’t use it because it doesn’t contain the original card information, making the transaction much more secure.
Yes, paying with a smartphone via digital wallets is generally considered safer. Every transaction requires biometric authentication (fingerprint or facial recognition) or a PIN on your device, a layer of security the physical card doesn’t have. Additionally, thanks to tokenization, your card number is never shared with the merchant, drastically reducing the risk of cloning or fraud.
Your payment data remains secure. Authorizing a payment always requires unlocking the phone via PIN or biometrics. In case of theft or loss, you can use services like Google’s ‘Find My Device’ or Apple’s ‘Find My’ to remotely lock or erase all data from the phone. This action immediately deactivates the payment tokens associated with the device, without needing to block your physical cards, which remain usable.
Compatibility is very broad but not yet universal. Most major banks and financial institutions in Italy and Europe support these services, but adoption depends on the individual bank and the card network (e.g., Visa, Mastercard, PagoBANCOMAT). Before trying to add a card, it’s always advisable to check compatibility on the payment service’s official website or by contacting your bank directly.
No, for the end consumer, using Apple Pay, Google Pay, and other digital wallets to make payments is free. There are no additional fees on transactions made via smartphone. Standard transaction costs are handled between the merchant, the bank, and the payment network, just as they are for payments with a physical card.
