"LINDA protects against phishing!" – This is the slogan of the 2026 Card Security campaign, a police initiative on the subject of card security. Fisherwoman LINDA helps card users remember the most important rules of behaviour when handling debit and credit cards. Each letter of LINDA's name stands for a mnemonic that can be used to prevent phishing.
According to the Federal Statistical Office's crime statistics, phishing attacks increased by 56% in 2024. In 2025, cybercrime in Switzerland saw a slight decline (–2.2%) for the first time in years. Card offences often begin with a phishing attack. In this scam, fraudsters contact potential victims via a text message or email, for example, and try to obtain personal data and card information by trickery. If you're not careful, you can lose a lot of money.
This can be avoided with LINDA: Each letter of her name stands for a mnemonic phrase that prevents card fraud.
#L = Links and attachments must be questioned
#I = Information must be carefully checked
#N = Neutral greetings are suspect
#D = Deadlines and urgency are fishy
#A = Addresses must always be verified
Take part in the big card security competition from 15 September to 14 October 2026 – and with a bit of luck, win an online voucher worth CHF 1,000!
Test your knowledge of the key rules for using debit and credit cards safely, and find out how LINDA the fisherwoman can support you.
