WP vCard Manager WordPress Plugin creates a new custom post type "vcards" where you can manage all common properties of a vcard. VCF File and QRCode with vCard data will be generated on save. hCard and h-card output is also supported. Alternative QRCode images with white or black color transparent are generated too.

Generated output is according to vCard RFC#2426, hcard spec, h-card spec
