Forgetting your card’s PIN or your password for online shopping could soon be a thing of the past. Biometric payments, which use unique physical characteristics like your face or fingerprint to authorize a transaction, are spreading rapidly. This technology not only promises to make payments faster and more convenient but also to significantly raise the level of security, representing a true revolution in how we manage our money. Italy, despite its strong ties to tradition, is proving to be fertile ground for this innovation, fitting into a European context undergoing a full digital transformation.
Biometric payments are based on the idea that every individual has unique and hard-to-replicate characteristics. Whether it’s the lines of a fingerprint, the map of blood vessels in the palm, the geometry of the face, or the pattern of the iris, biometric technology turns our body into our password. This approach eliminates the need to memorize complex codes or carry physical cards, offering a more seamless and integrated shopping experience. The adoption of this technology is on the rise, driven by the proliferation of smartphones equipped with biometric sensors and growing consumer trust.
The principle behind biometric payments is simple yet technologically advanced. In an initial phase, known as enrollment, the user registers their biometric features, such as a fingerprint or face, through a secure device like a smartphone or a terminal at a bank branch. This data is converted into an encrypted digital template and stored securely. When making a payment, the sensor captures the biometric data again in real time and compares it with the saved template. If there’s a match, the transaction is authorized instantly. This process, which takes just a few seconds, ensures that only the legitimate account owner can make the purchase.
The most common biometric technologies for payments are diverse and constantly evolving, each with its own unique features.
The European market for biometric payments is booming and is expected to grow exponentially in the coming years. Italy, despite starting from a strong tradition tied to cash, is decisively embracing digital innovation. In 2024, for the first time, the value of digital transactions surpassed that of cash. This shift is driven not only by new consumer habits but also by European regulations like PSD2 (Payment Services Directive 2), which has pushed for stronger authentication systems (Strong Customer Authentication), indirectly favoring the adoption of biometrics.
Several pilot projects have already been launched in Italy. As early as 2018, Intesa Sanpaolo and Mastercard launched a trial for a contactless biometric payment card in Milan, Rome, and Turin, which used a fingerprint to authorize transactions with no amount limit and no need for a PIN. Visa has also actively promoted the use of biometrics, highlighting that a large majority of Italian consumers are ready to use these technologies for payments. The growing trust in these solutions is a clear signal: the traditionally more cautious Mediterranean culture is recognizing the benefits of a system that combines innovation and security.
The benefits of biometric payments are undeniable. The main advantage is increased security. Biometric features are unique and nearly impossible to steal or replicate, unlike PINs and passwords. This drastically reduces the risk of fraud and unauthorized access. Another key strength is speed and convenience: transactions become faster and more seamless, improving the shopping experience both online and in physical stores. For businesses, this translates into lower operational costs related to fraud management and greater customer loyalty, as customers feel more secure.
However, the large-scale adoption of biometrics also raises important questions. Privacy is the main concern. Biometric data is extremely sensitive, and its collection and storage must be handled with the utmost care to prevent misuse or breaches. The General Data Protection Regulation (GDPR) in Europe imposes very strict rules on the processing of this data, classifying it as a “special category” that requires explicit consent and enhanced security measures. A breach of a biometric database would have far more serious consequences than a stolen password, as our biological data cannot be “changed.” Finding the right balance between technological innovation and protecting fundamental rights will be the real challenge for the future of these systems.
The future of payments is an increasingly integrated and invisible ecosystem where biometric authentication will play a central role. It is predicted that by 2025, a significant share of digital payments globally will use biometric technologies. Innovation doesn’t stop: networks like Mastercard and Visa are already working on solutions that could make traditional credit cards obsolete, combining biometrics and tokenization for even greater security. Artificial intelligence will help make recognition systems even more accurate and secure by analyzing micro-behaviors to prevent fraud in real time. This path will see a progressive standardization of technologies at the European level to ensure interoperability and a consistent user experience across all countries.
Italy is at the center of this transformation, with a market showing great interest and growing adoption by younger consumers. The challenge will be to accompany this transition by educating citizens about the benefits and risks of these new technologies while ensuring a solid regulatory framework that protects privacy without stifling innovation. The synergy between tradition and innovation could lead Italy to become a benchmark for adopting a payment system that is not only more efficient but, above all, safer for everyone—a crucial step in preventing risks like credit card cloning. The use of systems like two-factor authentication (2FA), already widespread, represents a bridge toward the full adoption of biometrics as a security standard.
Biometric payments represent much more than a simple technological innovation; they are a symbol of a cultural shift in our relationship with money and security. From facial recognition to fingerprints, these technologies offer a previously unimaginable combination of convenience and protection, promising to simplify daily life and effectively combat fraud. In Italy and across Europe, the path is clear: increasing digitalization and regulatory push are accelerating the adoption of these systems. Although challenges related to data privacy and security require constant attention, the benefits in terms of efficiency and protection are evident. The future where our body becomes the secure key for every transaction is no longer science fiction, but an increasingly concrete reality that will redefine the very concept of payment.
Yes, biometric payments are considered very secure, often more so than traditional methods like PINs and passwords. Your biometric features (fingerprint, face, iris) are unique and extremely difficult to replicate. Furthermore, the device doesn’t save a photo of your fingerprint or face, but rather an encrypted mathematical representation of it. This data is stored in an ultra-secure, isolated area of your smartphone (like Apple’s Secure Enclave), making it inaccessible to malicious actors.
In most cases, such as with Apple Pay and Google Pay, your biometric data never leaves your device. It is converted into an encrypted code and stored on a separate, secure hardware chip inside your smartphone or smartwatch. It is not sent to external servers or shared with the merchant, or even with Apple and Google themselves. This approach is designed to ensure maximum privacy and comply with strict regulations like Europe’s GDPR.
The process is simple and fast. When you’re in a store, you bring your smartphone or smartwatch near the contactless payment terminal (POS). An authorization request will appear on your device’s screen. At that point, you just need to look at the camera (for facial recognition) or place your finger on the sensor (for fingerprint). Once the system recognizes you, the payment is approved instantly. It all happens in a few seconds, with no need to enter any codes.
There’s no need to worry. If the system fails to recognize your fingerprint or face (for example, due to a wet finger, poor lighting, or an incorrect angle), the device will automatically ask you to use your alternative unlock method. You can then authorize the payment by entering the PIN, password, or pattern you normally use to unlock your phone. You’ll never run the risk of not being able to pay.
Yes, the use of biometric payments is very common in Italy. You can use them in almost any physical store, as they work on any contactless-enabled POS terminal. Today, the vast majority of stores in Italy are equipped with these terminals. For online purchases as well, more and more websites and apps allow you to pay using your smartphone’s biometric recognition, making transactions faster and more secure.
