If the QR code on a station is removed, falls off, is defaced or otherwise cannot be scanned:
open the Brick dashboard, navigate to the station page searching for the Station ID
Under 'QR Code' on the station's page in the dashboard hit 'Print QR Code'
You'll most likely want to print horizontally and/or adjust the scale of the print
Contact your local print shop for a sticker or contact your Partner Success Manager at Brick for a replacement.
