Card Configured To Receive Separate Battery

A method for inserting a battery into an electronic card comprising:

• providing an electronic card having electrical circuitry embedded in a thin, flexible substrate, the card having a cavity formed in a surface thereof for receiving a battery and tabs on at least two opposing sides of the cavity and extending over a portion of the cavity;
• bending the electronic card with the surface having the cavity being on a convex side of the card such that the tabs move away from each other when the card is bent;
• inserting a battery into the cavity while the card is bent, wherein the battery has a width that is wider than the distance between the opposing tabs when the card is not bent;
• and
• releasing the card to return to an unbent orientation wherein the tabs extend over portions of the battery, thereby retaining the battery in the cavity and in electrical communication with the electrical circuitry of the electronic card.

A method of transporting an electronic device such that it is not powered during transport, comprising:

• mounting an electronic card to a substrate, the electronic card being thin and flexible, and having electrical circuitry and at least one electronic component embedded therein, the electronic card being in an unpowered state when fastened to the substrate;
• mounting a battery to the substrate;
• and
• mailing the substrate with the electronic card and the battery mounted thereto, wherein the battery is configured to be inserted into a cavity in the electronic card by a recipient for powering the electronic device.
