Secure vCard Storage: Store personal information for vCards securely on your server, rather than using standard vCards.
Each vCard creation should generate a unique URL, embedded in a QR code for secure downloads.
Example: Scanning the QR code leads to a secure link that directly downloads the vCard without exposing the underlying data.
Protection Against Bots: Implement bot and crawler protection for vCards stored on your server.
Example: Using CAPTCHA when accessing the vCard download link can prevent automated access.
