Ecosystem

In business, an ecosystem is a structure in which multiple companies, services, technologies and users depend on one another and create value as a whole. Apple's ecosystem (iPhone + App Store + Apple Pay + iCloud) and Google's (Android + Play Store + Google Pay + Google Cloud) are examples of that arrangement: a platform at the center, with a multitude of participants around it.

QR codes are an unusual technology in that they span multiple ecosystems at once: payment (PayPay, WeChat Pay, UPI), authentication (TOTP, digital certificates), logistics (GS1, traceability) and marketing (access analytics, CRM integration). In every one of them, the QR code acts as the entry point to information.

The reason QR codes work so well as a common interface across ecosystems is that they are an open standard. No single company owns the technology: it is internationally standardized as ISO/IEC 18004, and anyone can generate and read codes free of charge. That openness is what underpins interoperability between otherwise separate ecosystems.

The flip side is that each ecosystem uses QR codes in a slightly different way, which can leave users confused. That a payment code and an informational code are indistinguishable at a glance is a problem whose resolution is expected to come from the spread of unified specifications such as GS1 Digital Link.
