Abstract: A method for a secured purchase process. The method may include encoding a device with a unique identification code related to a specific item, attaching the device to the item by a locking mechanism included in the device, receiving, by a receiver included in the device, a signal upon a completion of a payment transaction related to the unique identification code, enabling an unlocking movement of the locking mechanism upon receipt of the signal, and unlocking the locking mechanism to enable releasing the device from the item.

Abstract: Some embodiments of a low profile intramuscular auto-injector optionally comprise a contact surface contoured to fit a body surface. Optionally a height of the injector is less than ¼ a perimeter of the contact surface. Optionally a cover protects said contact surface. Optionally the device includes a priming mechanism coupled to the cover wherein removal of the cover activates the priming mechanism for priming the injector and/or increasing a height of the injector. Optionally the injector includes a cylindrical pharmaceutical reservoir rigidly attached to an injection needle. Optionally in a compact storage state the injection needle is at a low angle to the contact surface. Optionally during priming the needle and/or reservoir rotate to orient the needle at a higher angle to the contact surface.
