1. A non-transitory computer readable medium storing computer executable instructions that, when executed by a processor, cause a portable terminal to: capture an image of at least a part of an image forming apparatus; transmit image data containing the captured image to a network server that stores model information and image patterns indicating models of image forming apparatuses and consumables information indicating consumables in association with the models of the image forming apparatuses; receive consumables information indicating consumables stored in the network server in association with a model of the image forming apparatus identified based on the image data by pattern matching by the network server the transmitted image data from the stored image patterns; store the consumables information in a storage unit of the portable terminal; receive an input from a user related to consumables information indicating a consumable for verification; determine whether the stored consumables information in the storage unit includes the consumable for verification; and determine whether the consumables indicated by the consumables information is usable with the model when the received consumables information matches the stored consumables information.
