There are many barriers to purchase on mobile web, such as users being less likely to have enough time to complete the purchase, user distrust of mobile web sites / card forms, potential network disconnect during transaction, difficulty typing the card number (and I bet near 0% of potential customers know about the scan card feature), small screen makes it hard to know if you're really on the right product for you, etc. This might reduce barriers but there will still be some. Also, I doubt that Safari's credit card autofill had much impact on conversion overall - is there any data about this?
