Manan, for use cases that are heavily reliant on barcode scanning we do not recommend Glide’s standard scanner. We’ve partnered with Dynamsoft and can easily integrate their scanner into an existing Glide app. You are able to purchase plans directly through them on their website, Dynamsoft Barcode Reader SDK online store. Their scanner is much faster and has way more features, including QR code scanning. Before you purchase a plan please PM me so I can ensure you are on the appropriate plan.
Adding the Dynamsoft scanner into an app requires engineering effort. Due to this we only offer this solution to Business and Enterprise plans.
