Your bank card PIN may seem trivial—almost unimportant. That’s exactly what fraudsters exploit. They know common number patterns, observe people at ATMs, and test predictable combinations. Choosing a convenient code can open the door to your account—without you realizing it.
The PINs Criminals Try First
Security researchers have seen the same suspects for years: sequences like 1234, 0000, 1111. Also popular: 1212, 7777, 6969, or 2580 (a straight vertical line on the keypad). These combinations appear frequently in leaked data and forensic analyses. Many people also use years of birth, like 1990, or anniversaries—patterns that save attackers both time and effort.
If your PIN matches one of these common patterns—1234, 0000, 1111, 1212, 2580—change it immediately. If in doubt, block your card via 116 116 and create a new code.
Risky PINs and Better Alternatives

How to Choose a Strong PIN
A strong PIN looks random, has no link to your personal life, and avoids visible patterns. It doesn’t repeat numbers or follow sequences (1234, 4321), and it doesn’t trace a shape on the keypad. Use different PINs for different cards.
-
Avoid personal data: no birthdays, addresses, or license plates.
-
Avoid visual patterns: no lines, crosses, or squares on the keypad.
-
Change your PIN regularly—at least once a year or after travelling.
-
Memorize it—don’t write it down or store photos of it.
-
Use your banking app’s security tools: geoblocking, limits, and push alerts.
Safe Memory Tricks
Use a memory aid no one can guess. Example: pick four random digits and link them to a tiny story. Or roll a dice four times and use those numbers directly. Another option: take a random word, convert its letters to numbers using a phone keypad, and choose four digits—but only if the word isn’t personally connected to you.
Monitoring and Quick Reaction
A secure PIN is only the first layer of protection—vigilance is the second. Activate account and card notifications in your app. Check transactions regularly. Watch for small test charges of a few euros or pounds—criminals often use these to test cards before larger withdrawals.
Report any suspicious activity as soon as possible—your bank can freeze the card quickly and refund the money more easily.
Limits, Geoblocking, and Contactless Payments
Set daily limits for cash withdrawals and payments. Disable international card use if you’re not travelling. Contactless payments are convenient, but use your app to cap the amount. After several contactless transactions, most systems will require a PIN again—always insist on entering it yourself.
What to Do If You Suspect Fraud
Act immediately. Block the card via 116 116 or your banking app. Then notify your bank, note the time, place, and amount, and take screenshots. File a written report and, if necessary, request a police reference number.
Your Legal Protection
Under German law, you are not liable for unauthorized transactions. Until the card is reported lost, you may be charged up to €50, unless no PIN was entered or the bank cannot prove strong customer authentication. Refunds can be refused if you acted with gross negligence.
When Banks Can Refuse Refunds
-
You kept your PIN with the card or wrote it on the card.
-
You shared your PIN with someone (e.g., over the phone or via messenger).
-
You ignored clear ATM warnings (jammed slot, fake keypad).
-
You delayed blocking the card even though it was visibly missing.
Gross negligence begins where convenience replaces caution: using the same PIN for several cards, storing it on paper, or typing it loudly without covering the keypad.
Why Weak PINs Are Riskier Than Ever
Card fraud has become highly professional. Mini-cameras, fake keypads, and shoulder surfing give criminals access to PINs. Many ATMs allow three attempts; some offline transactions verify the PIN later. Combined with stolen cards or leaked data, simple PINs have a much higher success rate.
Social engineering adds another layer: criminals posing as bank staff may call and pressure you to “test” your card—asking for your PIN.
Everyday Security Habits
Always cover the keypad with your free hand—even if no one seems to be watching. Stop your transaction if the ATM looks or feels unusual. Use well-lit cash machines inside bank branches. Regularly check your wallet’s card slot. Keep your banking app and phone up to date—security patches close vulnerabilities.
Example: Creating a Strong PIN
Roll a dice four times: 6–1–5–3 gives you 6153. Too abstract? Use a random postcode from another town and adjust each digit by +1 or –1. For example, 93047 becomes 0415 when you apply this rule. The key point: no personal connection, no pattern, nothing guessable.
Added Protection: Digital Wallets and Insurance
When you pay with your smartphone or smartwatch, the terminal receives a token instead of your real card number—reducing the risk of merchant fraud. Still, the PIN may be required for larger amounts or limits.
Check if your account includes cyber insurance or fraud detection with callback verification.
Before travelling, plan for backups: store the 116 116 hotline outside your phone, keep a spare card in your wallet, and withdraw a small amount of cash. Activate geoblocking and lower withdrawal limits—so even in a worst-case scenario, your loss stays minimal.
Also note: company and prepaid cards often follow different rules. Review their limits, liability, and replacement policies. Some issuers allow one-time PINs or temporary card numbers for online purchases. Using these tools reduces both your risk—and your stress—after a loss or card block.
