What's the best mobile payment method to reduce abandonment?

I've been running my Shopify store for three years now, and mobile conversion has been a constant headache. Every time I look at my analytics, I see this frustrating pattern: mobile users browse extensively, add products to cart, but then mysteriously disappear before completing the purchase. It's like they hit a invisible wall during checkout. I've tried multiple payment gateways, simplified my checkout process, but something still feels off. The mobile experience just isn't smooth enough. My conversion rate on mobile hovers around 1.2%, which is painfully low compared to desktop's 3.5%. I know customers are using smartphones more than ever, so this isn't just a minor issue—it's potentially killing a massive chunk of potential revenue. I've heard whispers about one-click payments and streamlined checkout experiences, but implementing them feels technical and risky. What I need is a solution that doesn't require me to become a payment engineering expert overnight, but still makes purchasing as frictionless as possible for my mobile shoppers.
