Questions about this engagement
How was PCI DSS compliance achieved on the mobile devices?
Transaction data was protected with AES encryption and token-based authentication, and API keys were moved to server-side storage rather than being held on the device. The platform meets PCI DSS in full.
Does the app keep working when a device loses connectivity?
Yes. The architecture is offline-first: transactions are cached locally and synced automatically once the connection returns, which matters for ticketing in transit and at remote sites.
Which point-of-sale hardware does it support?
Card readers, barcode scanners and printers, through a device compatibility framework built to absorb Android fragmentation. Coverage across the client's IoT ecosystem reached 95%.
Which business systems does the platform integrate with?
Adyen for payments, SAP and Oracle on the ERP side, and Salesforce and HubSpot for CRM, alongside the connected point-of-sale hardware.
