Python Requires Chilkat v11.7.0+

QR Codes for Email, Phone, SMS and Location

See more QR Code Examples

Demonstrates QR codes that start an action on a phone. A QR code only holds text, and what happens on scanning depends on the form of that text: mailto: starts an email, tel: dials a number, SMSTO: starts a text message, and geo: opens a map at a latitude and longitude. A web address opens in the browser. Chilkat2-Python
