NFC (Near Field Communication) is a short-range wireless technology used for contactless payments. NFC is a transmission technology, and its security depends on the services that utilize it. At Vezo, we ensure security by using encryption with applets and keys embedded in the wearable, approved by Visa and Mastercard, to establish a secure communication channel. Additionally, Vezo does not store your actual card details on the NFC chip. Instead, an encrypted token is assigned to represent your card, ensuring your credentials are never stored or transmitted. This means that even if someone intercepts the wireless transmission, the data remains secure. Our NFC devices are passive (they don’t require a battery), which adds another layer of security. Since they are offline devices, they cannot be hacked remotely or online, making them inherently more secure than active, connected devices. This approach is commonly used in industries like payments, transport, and access control.
