The limitations of magnetic stripe cards, which led to widespread fraud, and the subsequent introduction of chip and PIN technology are discussed. The podcast further examines the vulnerabilities of contactless NFC cards, including digital pickpocketing, and offers advice on how to protect against fraud, such as enabling notifications and using mobile wallets.
