How do you scan a QR code?

Nowadays, every verification software especially SaaS solutions like electronic signature apps and document management solutions heavily depends on verifiable QR codes to prove the authenticity of any documents to the users/verifiers. 

QR cord is a verification system that uses Blockchain technology and smart contracts to combat fraudulent activities, document forgery, and data theft.

Here are some simple ways to scan QR codes using any smart device to verify data easily.

Here are the steps to scan a QR code using iPhone:
