The invention relates to a method of vending and authorizing age-restricted goods from a vending system. The vending system comprises a vending machine and a video camera, or equivalent means, for capturing an image of a person desiring purchasing of an age-restricted good. An image of the person is captured and transmitted to a (remote) age verification centre. If, from the person image, it can be determined at the age verification centre that the person is of the required age for purchasing the age-restricted good, a purchase authorization signal from the age verification is received centre at the vending system. Subsequently, the age-restricted good may be provided from the vending machine. On the other hand, if, from the person image, it can be determined at the age verification centre that the person is not of the required age for purchasing the age-restricted good, a purchase denial signal is received from the age verification centre at the vending system. The age-restricted good will then not be provided to the person. In some cases, it will not be possible to determine whether or not a person should be authorized to purchase the age-restricted good. Only in those cases, an identification request signal will be received at the vending system from the age verification centre to present an identification document.
