There’s a particular kind of exhaustion that comes with traditional performance testing. You spend weeks building perfect load scenarios, run them overnight and wake up to a wall of red in your monitoring dashboard. Half your day disappears into log files, trying to piece together what went wrong. And just when you think you’ve got it right, a minor UI update breaks everything and you’re back to square one. If this sounds familiar, you’re not alone.

The digital economy has upgraded from simple transactional interactions with users. Now consumers demand the Autonomous Digital Experience (ADE) – the customer journey is driven by predictive, self-learning systems, which is essential for competitive success. This is driven by Predictive Personalisation, which uses machine learning to predict personalised affinity and intent of user actions, delivering personalised content, products and messages in real-time.

They support P2P payments, merchant transactions, loyalty programs, identity services, transit use cases and embedded financial services. Reports from McKinsey, Deloitte and Worldpay show strong growth in digital wallet usage. Wallets now power a large share of global e-commerce and POS transactions. Adoption is rising in both developed and emerging markets. Many organisations can launch a wallet fast. Scaling it is harder.
