A system and method are disclosed in which cash deposits may be made at merchant locations who support such deposits. Using a mobile phone or other hand-held device, a bank customer requests a cash deposit from a banking app, receives a barcode on the mobile device, the barcode containing embedded information indicating the cash deposit amount, and presents the barcode to the merchant, along with the cash to be deposited. Once the transaction with the merchant is complete, the account of the bank customer's account is credited with the cash amount. The bank uses behavioral and historical data of the bank customer to customize a cash deposit limit for the customer.
