Mastercard Asia to patent Tangle-based device billing system

The patent claim proposes a pay-as-you-go system that uses a transparent data storage system and aggregation. Users must provide their credentials to gain access to copiers and 3D printers and billed strictly for what they used. The proposed data storage systems could be based on a Tangle or a generic blockchain. The patent makes no mentions of the Iota network or its currency, as the system could also be used in private environments.
