Show QR Code for Address

A Quick Response code, commonly known as a QR code, is an image containing scannable information. In the context of Bitcoin and Counterparty, QR codes usually represent Bitcoin addresses. (Although private keys can also be displayed as QR codes for paper wallets as well.) QR codes make it easier for users on mobile devices to send GASP, ASP, or user-created assets to your address by using the built-in camera of their device.

It is also a great way to display a GASP address on a poster or sign. Someone passing by will only need a camera or phone with a camera (even low resolution will do) in order to save your address for later payment. Also if they have a GASP wallet on their device, they will be able to send money immediately.

In AspireWallet, the QR codes always represent your public address. You can make the QR code of an address public, just as you would with the regular address.

To display the QR code for your address, simply click on “Address Actions” and then click on “Show QR Code”.

You can then right-click and save the QR code image for printing, or later use. It is also possible to scale the QR code to a larger size, as long as you preserve the ratio between width and height so that it stays a perfect square. Always leave a white border around the QR code so that it can be scanned correctly. Also make sure that you preserve the contrast of colors: black QR on a white background.
