It is the world’s largest shopping event of the year. And a battle for the best bargains. A number of online retailers such as Amazon, Microspot and Zalando tempt shoppers with huge Black Friday discounts. But this is also a busy time for fraudsters. With tempting offers and fake online shops, they induce innocent consumers to buy, thereby obtaining their data.
A number of online shops use two-factor authentication. This ensures that credit card payments are secure and can be carried out in various different ways. Depending on the provider, you set a code once and then enter this additional piece of information during each payment transaction or you receive a new code by text message for each purchase you make. Other providers, meanwhile, ask for confirmation in an app. When shopping online, it is important that you avoid making ill-considered purchases and keep an eye on what you are spending, no matter how attractive the deals are on Black Friday.
