Never disclose any personal access data, such as contract numbers, card numbers or security codes in case you are asked for such. Never disclose such data, even if allegedly requested by UBS. UBS will never take the initiative to ask you for such data - neither by telephone nor by e-mail or via the Internet.
After you log in, use your Access Card and card reader to confirm only character strings that you have entered or determined yourself. In this way, you can make sure they are correct. For example, these may be account numbers when making a payment or changes to your own contact data (e.g. telephone number).
