How to Configure and Customize rz_vCard for Your Project

How to Fix Common rz_vCard Import and Export Errors You can fix most rz_vCard import and export errors by changing the file version, fixing text encoding, or breaking large files into smaller pieces. Moving contacts between phones, email apps, and customer databases often causes formatting errors. Most systems will drop your files if they find a single misplaced character or an old file version. Mismatched File Versions

Platforms like iCloud, Google Contacts, and Microsoft Outlook use different standard formats. An old format can stop an entire transfer.

The Problem: Your file uses version 2.1 or 4.0, but your new application requires version 3.0.

The Symptoms: The system shows an “Invalid Format” error or fails silently without saving anything.

The Fix: Open the .vcf file in a plain text editor like Notepad. Find the line that says VERSION:2.1 or VERSION:4.0. Change it to read VERSION:3.0. Save the file and upload it again. Broken Characters and Special Symbols

Names with accent marks, emojis, or foreign letters frequently cause file structures to break.
