Invisible Giant
One code every wallet in Indonesia reads.
In the Global South, interoperability is not left to the market. The state mandates one standard, and every wallet becomes a public rail.
Interoperability is not always left to the market. Sometimes the state simply mandates it.
By 2019, Indonesia had dozens of wallets, each with its own QR code, so a shop needed a wall of stickers to be paid. The central bank set one national standard, QRIS, and required every wallet to read it. Some 26 rival providers were unified onto a single rail; today around 42 million merchants, most of them small shops, accept the one code, and about 59 million people pay with it, past every target set.
The decision that mattered: make the standard a public mandate, not a private race.
In the Global South, one mandated standard turns every wallet into a shared public rail.
