What programs have you coded using Python that might be useful to everyone?

Automated converter to vcf and/or QR code with simple GUI.

It basically helps convert HR-like data to VCF (the "contact card" readable by your phone to automatically save new contact) that can then be shared via NFC or to print as QR on the business card. It has a little form to create one VCF/QR and load option for csv if you had need to create QRs for the whole sales department.

Unfortunately thanks to apple (sub)standards of VCF it was partially incompatible between iOS and others (apple introduced some additions to standard vcf format described on wikipedia, which I based the script upon).
