Security First for Small Business Financials
Small business ledgers store sensitive customer balances, supplier credits, and cashier records. Storing this information in plain SQLite exposes businesses to data theft if a device is stolen. For AZ Khata, we implemented 256-bit AES database encryption using SQLCipher for Android.
Device-to-Device Peer Synchronization
Instead of routing every checkout transaction through an expensive cloud server, AZ Khata supports local socket discovery over Wi-Fi. Cashier phones communicate directly with the manager’s primary terminal, updating running balances in real time.
