Scan barcode from Iphone Keyboard

I am using an online based inventory tracking system called Tracmor. I'm wondering if there's an app for Iphone or some feature that allows you to scan barcodes from your iphone keyboard. The way I am able to input data inventory data into tracmor is by selecting the field in the Tracmor online portal, which pulls up the iphone keyboard. Ideally, I would like to scan the bar code from this point for the field. I know this is possible for android, but I have not found the solution for iphone. I am currently using an Iphone6.

Thank you, Maya
