vCard QR Code Generator (Digital Business Card & Contacts Builder) — Reference Guide

Create contact vCard 3.0/4.0 QR codes containing full name, phone number, email, company, title, address, and website for instant scanning into smartphone address books.

Key Parameters & Controls

versionstring

The vCard specification standard to target, typically '3.0' (RFC 2426) for universal native iOS/Android camera compatibility, or '4.0' (RFC 6350) for modern IANA features and UTF-8-by-default encoding.

formattedNamestring

The display full name mapped to the 'FN' property (e.g., 'Dr. Jane Doe'), accompanied by structured name components ('N:Doe;Jane;;Dr.;').

contactChannelsobject

Key-value map containing telecommunications records including 'TEL' (with TYPE=WORK,VOICE or CELL), 'EMAIL' (INTERNET address), and 'URL' endpoints.

organizationDetailsobject

Professional metadata mapping to 'ORG' (company or unit name), 'TITLE' (job designation), and 'ROLE' fields within the payload.

postalAddressobject

Structured street address mapped to the 'ADR' property (e.g., ';;100 Market St;San Francisco;CA;94105;USA').

errorCorrectionLevelstring

QR Reed-Solomon error correction level ('L' ~7%, 'M' ~15%, 'Q' ~25%, 'H' ~30%), where 'M' or 'Q' is recommended to balance data capacity and scan reliability.

Pro Tips & Best Practices

Common Gotchas & Troubleshooting

Smartphone camera scans the QR code as raw plain text rather than prompting to 'Add to Contacts'.

Verify the payload starts strictly with 'BEGIN:VCARD\r\nVERSION:3.0\r\n' without leading whitespace or byte order marks (BOM), ensure valid CRLF terminators on every line, and end with 'END:VCARD'.

QR code becomes overly dense, distorted, and difficult for standard mobile cameras to decode in low light.

Lower the error correction level from 'H' to 'M' or 'L' if no logo overlay is used, and omit non-essential fields (such as embedded avatars or extensive notes) to lower the QR version matrix density.

Accented or non-ASCII characters appear corrupted or as garbled text (mojibake) on imported contacts.

For vCard 3.0, explicitly declare the character set parameter on affected properties (e.g., 'FN;CHARSET=UTF-8:René Müller') or ensure the QR encoder generates an explicit UTF-8 byte sequence with ECI (Extended Channel Interpretation) 000026 header.
