QR code error correction determines how much damage the code can withstand while remaining scannable. L (Low) recovers 7%, M (Medium) 15%, Q (Quartile) 25%, H (High) 30% of data. If you plan to add a logo in the center, use H level for best reliability.
Maximum capacity depends on version and error correction level. At Version 40 with L-level correction: 7,089 digits, 4,296 alphanumeric, 2,953 bytes, or 1,817 Chinese characters. For URLs and short text, lower versions are typically sufficient.
The vCard QR code supports: name, company, job title, phone, email, website, and address. When scanned, it can be saved directly to the phone's contacts — one of the most popular ways to share digital business cards.
