A QR code (fast response code) is a type of bar code that stores digital information in its data matrix. It was first introduced in 1994 and since then it has become an omnipresent feature for various products, including smartphones, mobile payment systems and even certain industrial equipment. QR codes are known for their high security level, as they can only be scanned by devices with correct scan.

How do you use the payment function of the QR code in your Ethereum portfolio?

To use the payment functionality of the QR code in your Ethereum portfolio, follow these steps:

• Open the Ethereum Waller Application: Go to the Ethereum wallet app on your smartphone or computer.
