6. Please click "Bind" button to bind the device. If the Bind button is greyed off, this means the binding code is expired. Principal account holder has to extend the binding code's expiry time by going to merchant platform > Sub-account > "CoinSend" (Actions column) > "Bound CoinSign device" tab and click on the extend icon > change the expiry time to a later time and submit the changes. Once this is done, the sub-account holder can pull down the screen of the CoinSign App to refresh the screen and the "Bind" button should now be clickable.<br>
