Online broker E*Trade is now offering a mobile deposit app for the iPhone, enabling customers to electronically deposit checks to their brokerage or E*Trade bank accounts remotely using the smart phone’s camera.

Eligible customers simply photograph the front and back of a paper check with the iPhone’s built-in camera and upload the deposit electronically via E*Trade’s mobile banking and investing application, according to today’s release. The transaction is complete once the deposit amount and selected bank or brokerage account are confirmed, said E*Trade.
