An electronic card holder includes a fixed member, a tray slidably attached to the fixed member and defines a notch thereon, and a latching member. The latching member includes a main body fixed to the fixed member, a pressing portion extending from the main body and a latching portion extending from the main body towards the fixed member. When the latching portion is received in the notch, the tray is engaged with the fixed member. When the latching portion is driven to move away the notch by an external pressure applied on the pressing portion, the tray is disengaged from the fixed member.
