Last year, a woman in Manchester ordered a €30 pair of headphones from an online store she had never used before. She entered her credit card number, her address, her phone number, and her email. The headphones arrived. They were fine.

Three weeks later, €2,400 disappeared from her bank account in a series of small transactions she did not recognise. The store had been compromised. Her card details were sold on the dark web before her headphones even shipped.

Stories like this are not rare — they are routine. And the frustrating part? Most of it is preventable. Knowing how to shop online safely does not require technical skills. It requires breaking a few habits you probably do not even realise you have.

Mistake 1: Saving Your Card on Every Website

It is convenient. You check out faster. And you have probably done it on dozens of sites without thinking twice.

But every site that stores your card details is a potential breach waiting to happen. In 2024, over 1,100 e-commerce data breaches were reported globally. Each one exposed thousands of stored payment cards. The convenience of one-click checkout is not worth the risk of handing your card number to a database you have no control over.

The fix: Stop saving cards on websites. Enter your details manually each time, or better yet — use a payment method that does not require sharing your card details at all.

Mistake 2: Using the Same Card for Everything

Your salary goes into your main account. Your main debit card is linked to it. And you use that same card to buy a €5 app, subscribe to a streaming service, and order from a new online store you found on Instagram.

This means every online merchant has a direct line to your primary bank account. If one of them gets compromised — or turns out to be fraudulent — your entire balance is exposed.

The fix: Separate your online spending from your main account. Use a dedicated card with a limited balance, a virtual card, or a prepaid code for online purchases. That way, the worst-case scenario is losing the prepaid amount — not your rent money.

Mistake 3: Shopping on Public Wi-Fi

The coffee shop, the airport, the hotel lobby — public Wi-Fi feels convenient, but it is one of the easiest environments for attackers to intercept your data.

A technique called a “man-in-the-middle” attack allows someone on the same network to capture the data flowing between your device and the website you are using. If that data includes a credit card number, they have it.

The fix: Never enter payment details on public Wi-Fi. If you must, use a VPN to encrypt your connection. Or use a payment method that does not involve typing in sensitive card information — such as a prepaid code that works as a one-time payment token.

Mistake 4: Ignoring the URL Bar

Phishing sites have become remarkably convincing. A fake website can look identical to the real one — same logo, same layout, same product photos. The only giveaway is often the URL.

Common tricks include replacing letters (amaz0n.com instead of amazon.com), adding extra words (amazon-deals-shop.com), or using a different domain extension (.net instead of .com).

The fix: Before entering any payment information, check the URL carefully. Look for “https://” (the ‘s’ means the connection is encrypted) and verify the domain name matches the official site. If something feels off, it probably is.

Mistake 5: Clicking Payment Links in Emails

“Your order could not be processed. Click here to update your payment details.” You have seen this email. Maybe you have even clicked it.

Legitimate companies rarely ask you to re-enter payment information via email. When they do, the email is almost certainly a phishing attempt designed to capture your card details.

The fix: Never click payment links in emails. Instead, go directly to the website by typing the URL in your browser. If there is genuinely a problem with your order, you will see it in your account dashboard.

Mistake 6: Not Checking Your Statements

Fraudsters know that most people do not review their bank statements line by line. That is why they often start with small charges — €1.99 here, €4.50 there — to test whether a stolen card is active. If nobody notices, the bigger charges follow.

The fix: Review your statements at least weekly. Set up notifications for every transaction on your card. The earlier you catch an unauthorised charge, the easier it is to reverse.

Mistake 7: Trusting a Website Just Because It Looks Professional

In 2026, anyone can build a professional-looking website in an afternoon. A polished design does not mean a legitimate business. Fake online stores are one of the fastest-growing categories of online fraud, particularly around holiday shopping seasons.

Warning signs to watch for:

  • Prices that are too good to be true — 80% off a new iPhone is not a deal. It is bait.
  • No physical address or contact information — legitimate businesses tell you where they are.
  • Only accepting bank transfers or crypto — these are harder to reverse than card payments.
  • No customer reviews outside the site — if the only reviews are on the store itself, they are likely fake.
  • Recently created domain — you can check a website’s age using free WHOIS lookup tools.

The fix: Research unfamiliar stores before buying. A quick search for the store name plus “scam” or “review” can save you from a costly mistake. And when shopping on a site you are not sure about, use a safe online payment method that limits your exposure — like a prepaid code from Sasono, which does not require you to share any bank or card details with the merchant.

The Real Problem: We Give Away Too Much

Every time you type your credit card number into a website, you are trusting that website — its developers, its hosting provider, its security practices, and every third-party service it uses — with direct access to your money.

That is a lot of trust for a pair of headphones.

The smartest shift you can make is simple: stop giving every website your real payment details. Use methods that put a barrier between your bank account and the merchant. Prepaid codes, virtual cards, payment wallets — all of these reduce what a merchant (or a hacker) can access if something goes wrong.

The Bottom Line

Learning how to shop online safely is not about being paranoid. It is about being practical. You lock your front door — not because you expect a break-in every day, but because the cost of prevention is tiny compared to the cost of getting it wrong.

Online payment security works the same way. Small changes — not saving cards, separating spending accounts, using prepaid payment methods, checking URLs — add up to a dramatically lower risk of losing money to fraud.

Your money. Your data. Keep both where they belong — with you.
