The Quickei WhatsApp Bot enables conversational banking — users can check balances, send money, exchange currencies, and view history directly from WhatsApp.

​
Features

Balance Check

Check wallet balances across all currencies by sending “balance” or “solde”.

Send Money

Transfer funds with a guided step-by-step flow including PIN verification.

Currency Exchange

Exchange between currencies with real-time rates — “change” or “exchange”.

Transaction History

View recent transactions by type — send “history” or “historique”.

​
