Evolution on the Wrist: From Tradition to Digital Innovation

The watch has always played a role beyond simple timekeeping. It is a style accessory, a status symbol, sometimes a family heirloom. Today, this highly personal object is enriched with a new dimension: the digital one. Mediterranean culture, and Italian culture in particular, despite being tied to traditional gestures like using cash, is embracing the convenience of electronic payments with surprising speed. The smartwatch perfectly embodies this transition, maintaining its classic form while hiding sophisticated technology inside.

The heart of this innovation is NFC (Near Field Communication) technology, a short-range wireless communication system that allows two devices to exchange data securely and quickly. When you bring your smartwatch close to an enabled payment terminal (POS), the NFC chip integrated into the watch communicates with the reader to authorize the transaction. It is the same principle as contactless cards, but with a superior level of convenience: you don’t even have to take your wallet out of your pocket.

The process for paying with a smartwatch is incredibly simple and fast. Once you have configured your credit, debit, or prepaid card in the appropriate application on your smartphone, you are ready to start. At the time of payment, you just need to activate the function on your watch, usually with a double click on a button or by opening the wallet app, and bring the watch face close to the POS reader. In a few moments, a slight vibration or an acoustic signal will confirm that the transaction was successful. This speed is ideal in many situations: when grocery shopping, taking public transport, or when you are in a hurry.

The magic behind this simplicity hides a very robust security mechanism called tokenization. When you add a card to your digital wallet, the real card number is not stored on the device nor transmitted to the merchant. Instead, a “token” is created, which is a unique digital code associated with that specific card and that device. During payment, it is this token that is sent to the POS, protecting your sensitive data. This is one of the reasons why secure payments with tokenization are considered extremely reliable.

For iPhone owners, the Apple Watch represents the natural extension of their digital ecosystem. Apple Pay on watchOS is renowned for its fluidity and integration. Configuration is guided and takes place via the Watch app on the iPhone: simply access the “Wallet & Apple Pay” section and add your cards. Once the procedure is complete, which takes a few minutes, the cards are ready for use directly from your wrist.

User experience is one of Apple’s strong points. To pay, simply press the side button of the Apple Watch twice to view the default card. By bringing the watch close to the POS, the payment is authorized instantly. Security is guaranteed by the fact that the watch must be unlocked and on the user’s wrist to function. If it is removed, it automatically locks and requires the PIN code to be reactivated. This system, combined with tokenization, makes Apple Pay one of the safest solutions on the market, supported by the majority of Italian banks.

Wear OS and Google Wallet: Versatility on the Wrist

Wear OS is Google’s operating system for wearable devices, adopted by a wide range of manufacturers such as Samsung, Google (with its Pixel Watch), Fossil, and many others. This variety offers users a great choice in terms of design, functionality, and price. The integrated payment system is Google Wallet (formerly known as Google Pay), which allows you to digitize payment cards, event tickets, loyalty cards, and more.

Configuring Google Wallet on a Wear OS smartwatch is similar to Apple Pay. It is managed primarily through the Google Wallet app on the connected Android smartphone, where you can add and manage cards. To pay, simply open the Wallet app on the watch and bring it close to the NFC terminal. In this case too, it is necessary to set a screen lock (PIN, pattern, or password) to ensure security. Compatibility with Italian banks is very broad, making Google Wallet a versatile and accessible solution for the vast majority of Android users.

Security First: Wrist Payments Are Reliable

One of the most common questions concerns security: is it really safe to pay with an object we wear on our wrist? The answer is a definite yes. As mentioned, tokenization is the first and most important level of protection: your real card data is never exposed. Secondly, both watchOS and Wear OS require setting a secure unlock method on the device, such as a PIN or pattern. The watch automatically locks when removed from the wrist, preventing anyone else from using it to make payments.

In case of loss or theft of the smartwatch, it is possible to immediately block payment functions remotely via Apple’s or Google’s “Find My” services. This makes wrist payments even safer than a physical card, which, if lost, could be used by malicious actors for contactless purchases under the threshold that does not require a PIN. The combination of on-device authentication and the possibility of remote locking offers unparalleled peace of mind, making the comparison between contactless vs chip and pin even more favorable to new digital technologies.

The Italian and European Market: An Unstoppable Trend

The adoption of digital payments in Italy and Europe is growing constantly and rapidly. According to data from the Innovative Payments Observatory of the Politecnico di Milano, in 2024 the value of digital payments in Italy surpassed that of cash for the first time. Payments via smartphones and wearable devices showed explosive growth, reaching 56.7 billion euros with a 53% increase compared to the previous year. Transactions specifically with wearables alone touched 2.5 billion euros, marking a +57% increase.

This trend is not isolated to Italy. Across Europe, contactless payments have become the norm. Already in the second half of 2022, over 53% of all card transactions in the euro area took place in contactless mode. The pandemic certainly accelerated this change, accustoming consumers to the convenience and safety of touch-free payments. Today, this habit has consolidated, and using a smartwatch to pay is no longer seen as a technological oddity, but as a natural evolution of the digital wallet, accepted by an increasing number of merchants, from large chains to small neighborhood shops.

Real Pros and Cons: A Practical Analysis

Adopting smartwatch payments offers undeniable advantages. The most obvious is convenience: paying without having to search for your smartphone or wallet is a liberating experience, especially when your hands are full, you are playing sports, or traveling light. Speed is another point in favor, reducing waiting times at the checkout. Then there is security: as we have seen, the integrated protection systems are superior to those of a traditional card. Finally, one cannot deny a certain “wow factor” which, although superficial, makes the experience pleasant and modern.

However, there are also some disadvantages to consider. The biggest limit is battery dependence: if the watch is dead, the payment function is obviously unavailable. The initial investment for a good quality smartwatch can be significant, and not all banks or card networks might be supported by the chosen service, although compatibility is constantly expanding. For some users, the initial configuration might seem slightly complex, but the guides integrated into the apps are designed to simplify every step as much as possible.

In Brief (TL;DR)

Discover how to transform your smartwatch into a digital wallet by configuring cards for fast and secure contactless payments with Wear OS and watchOS operating systems.

We will analyze step-by-step the procedures to enable contactless payments on both Apple Watch with watchOS and smartwatches with Wear OS.

You simply need to activate the wallet function on your wrist and wait for a vibration or sound to confirm the transaction is complete.

What happens if I lose my smartwatch containing my cards?

If your device is lost or stolen, your financial data remains protected thanks to the mandatory screen lock that activates immediately upon removal from the wrist. Furthermore, you can use remote tracking services provided by Apple or Google to locate the device and block payment functions instantly. This adds a layer of security that physical wallets cannot offer.

Can I make a payment if my smartwatch battery is dead?

No, the smartwatch must be powered on to perform NFC transactions. Dependence on battery life is considered one of the main disadvantages compared to traditional plastic cards.
