A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.

An embodiment of an electronic vaping device includes: a memory; a light emitting device configured to optically transmit information associated with the electronic vaping device to an external device; and processing circuitry coupled to the memory and the light emitting device. The processing circuitry may be configured to: collect the information associated with the electronic vaping device; store the information in the memory; detect a triggering event; and initiate optical transmission of the information by the light emitting device in response to detecting the triggering event.
