Easy Steps to Connect Your OPZ NFC Card with dApps
Integrating the OPZ NFC Card with decentralized applications (dApps) on the OPZ app is straightforward. Here's a user-friendly guide to get you started:
Check Device Compatibility: First, ensure your device has NFC capabilities and is compatible with the OPZ app.
Navigate to the Web3 Browser: Open the OPZ App on your device and go to the built-in Web3 browser. This is where you can access various dApps.
Choose Your dApp: Select the dApp you wish to use from within the OPZ Web3 browser.
Connect with WalletConnect: When you choose to interact with a dApp, typically, you'll use WalletConnect or a similar service within the dApp. This creates a secure connection between the dApp and your OPZ NFC Card.
Authenticate with a Tap: A popup will appear asking for authentication. At this point, tap your OPZ NFC Card on the back of your NFC-enabled device.
Additional Authentication Steps:
Biometric Verification: After tapping, your phone will request a biometric verification, such as facial recognition or Touch ID.
Two-Factor Authentication (2FA): If you have enabled an extra layer of security, you will be asked to enter a code sent to your phone or email as part of 2FA.
Complete the Interaction: The OPZ NFC Card automatically signs the blockchain transaction upon successful verification.
