The Technology Stack Wars
The Technology Stack Wars
The infrastructure wars that play out are largely invisible to customers, but they fundamentally shape which wallets win in different markets. Western providers bet heavily on near-field communication technology, which lets users tap their phones against existing contactless terminals. It feels seamless but requires merchants to upgrade their hardware.
Asian markets took a different path, embracing QR codes that need nothing more than a printed square on a checkout counter. China’ s merchants adopted mobile payments at breakneck speed precisely because they didn’ t need expensive new terminals. Apple’ s device-specific tokens keep credentials off servers – good for security, awkward for multi-device users. Competitors who centralise tokenisation make switching between devices effortless but create more tempting targets for hackers.
Fraud detection has become an arms race, with providers deploying machine learning models that analyse spending patterns in real-time to spot suspicious transactions.
