Create Unique Barcodes for clients to scan my Recips/Meals

Hi there,

My question is - Is there way to get unique barcodes or QR Codes to link to my recipes/meals for my clients?

I'm currently building my meal plan books and would like to add a barcode to it so my clients can just scan it and it pops up on their my fitness pal profile?

I've seen it get done how is it possible?

Thanks
