The combination of the user's thumbprint with the bioimpedance signature defines a unique identity data combination for the user that can be compared to stored identity data combinations of authorized users. If the identity data combination of the active user matches, within a statistical confidence level, a stored identity data combination of an authorized user, the vaping device “unlocks” its heating chamber such that power is supplied to the coil/heating element for vaporizing e-juice. ## Claims ### Claim 1 A method for age authenticated vaping, comprising: reading a thumbprint and measuring a bioimpedance signature, wherein the thumbprint and bioimpedance signature define an identity data combination for an active user of a vaping device; based on the identity data combination for the active user of the vaping device, determining that the active user is an authorized user of the vaping device; and unlocking the vaping device such that power is supplied to a coil operable to vaporize e-juice. ### Claim 2 (depends on 1) The method of claim 1, wherein determining that the active user of the vaping device is an authorized user of the vaping device comprises comparing the identity data combination of the active user with one or more stored identity data combinations associated with authorized users of the vaping device. ### Claim 3 (depends on 2) The method of claim 2, further comprising calculating that, within a statistical confidence interval, the identity data combination of the active user is equivalent to one of the one or more stored identity combinations associated with authorized users of the vaping device. ### Claim 4 (depends on 1) The method of claim 1, wherein the thumbprint is read simultaneously with measuring the bioimpedance signature. ### Claim 5 (depends on 1) The method of claim 1, wherein there are a plurality of authorized users of the vaping device and each authorized user is associated with a unique identity data combination. 6 The method of claim 1, further comprising: based on the identity data combination of the active user, updating a bioimpedance signature stored in association with an authorized user. ### Claim 7 (depends on 1) The method of claim 1, further comprising providing visual feedback to the active user of the vaping device that the thumbprint has been successfully read. ### Claim 8 A vaping device for age authenticated vaping, comprising: a heating coil operable to vaporize e-juice;
