Hi there, @williamwm1 - thanks for reaching out to us here on the Seller Community! Good to hear from you again.
Would you mind clarifying your question/post a bit more? - Are you inquiring about using an iPad or iPhone camera software to scan barcodes? If so, this capability is currently considered a Feature Request for our Hardware. As of now, we only offer the ability to scan barcodes by using an approved barcode scanner for your POS.
If I missed the mark on interpreting your question, feel free to shoot me a reply here! We are here to help.
