Card security

Payments with Viseca cards are now more secure than ever. Nonetheless, fraudsters are always finding ways to get hold of cards or card details, so you should always err on the side of caution. If you take the main precautions, you will always be one crucial step ahead of the card fraudsters - at home, on the move and when travelling.

Security measures

Sign your new credit card immediately on the reverse. Cut up your old card's magnetic strip and chip.
Do not use personal details such as date of birth, car registration etc. as your PIN code. Never write down your PIN code, and make sure nobody is looking over your shoulder when you are entering the code.

Please note:
Writing your PIN code on the card, keeping it in your wallet with the card or leaving your card unattended (including in a car, while playing sport or at the office) constitutes negligence and may mean you are liable for the damages suffered.
Do not choose a password for "one" that you are already using for other online accounts. The same applies to your e-mail account. Encrypt your passwords as well as possible.
Never divulge your credit card details (card number, expiry date, security code on the reverse of the card) for information purposes if you are not placing a telephone order or reservation. Requests for credit card details and passwords by e-mail or phone are usually spurious. Delete the e-mails immediately, without clicking on links or opening attachments. 
Contact us immediately if your card is lost or if it appears that your card has been fraudulently used. The emergency number for the Viseca 24-hour card blocking service is: +41 58 958 83 83. You should also make a note of your credit card number and keep these numbers separate from the card, in a safe place.

NEVER allow third parties to distract or even "help" you at machines. Inform your bank or the police if you notice anything suspicious about a machine (ATM, ticket machine, automated refuelling machine). Have your card blocked immediately if it is retained by a machine.

Travel tips

Before you travel

  • Check the expiry date on your credit card and memorise the PIN code.

  • Save the Viseca emergency telephone number +41 58 958 83 83 (24-hour service) in your mobile phone.
  • Set up your free "one" account, download the app and turn on push notifications. You will then have control over your spending even while on holiday.
  • Take a second card with you as a back-up.

During your trip

  • Keep your card in a safe place, as if it were a large quantity of cash.
  • While travelling, you should keep your card on you at all times or lock it in the hotel safe. Under no circumstances should you leave it unattended in a suitcase, in a car or on the beach.
  • Keep your credit card receipts in case of complaints.
  • Always request bills in the national currency.
  • If your card is lost or stolen, call the Viseca 24-hour card blocking service immediately. Always report any theft to the police and ask for a copy of the subsequent police report.

Control measures

You can easily check your spending at any time with the free"one" app and the handy text message services. If there are any discrepancies, contact our customer service immediately.
Each time you make a payment, check that the amount is correct before you sign or enter the PIN code. Always enter the amount under "Total" if it is not already printed or entered. Always draw a line before the amount.
Keep all order, booking, return and cancellation confirmations, along with your correspondence with the merchant. This documentation is essential when making claims and complaints.
When registering your credit card in an app store, please check in the settings whether in-app purchases have been turned on. There are various types of automatic charges: game currency, experience points, upgrades, activations, maps for navigation systems, subscriptions, etc. Find out about these terms before installing an app.
