Payment Wallet Security Testing: Mobile Wallets, Digital Payments, and Stored Value for Australian Enterprises

Payment wallet applications — mobile wallets, digital payment platforms, stored-value cards — handle real monetary value, making security testing critical. Testing covers: transaction integrity (can amounts, recipients, or currencies be manipulated?), double-spending prevention (can the same funds be spent twice through race conditions?), balance manipulation (can account balances be artificially inflated?), peer-to-peer transfer security, top-up and withdrawal flow integrity, and referral/reward program abuse. Our extensive experience testing payment wallets across multiple geographies identifies the business logic flaws that lead to direct financial loss.
