RECEIPTIUM is a transaction management, consumer engagement and identity platform (CEIP) that allows business applications to publish their detailed receipts, invoices, purchase orders or electronic documents or data artefacts to their consumers in real-time and anonymously (optional) via the RECEIPTIUM Network. Consumers are then able to access all their “publications” via the RECEIPTIUM web application, on their desktops and smartphones, whilst extracting value from the entire Consumer-to-Business (C2B) or business-to business (B2B) relationship value chain. RECEIPTIUM’s proprietary solution aggregates and organises all the published data artefacts from retail and non-retail businesses on behalf of the consumer and is designed to redefine the C2B or B2B internet interactions like never before using the receipt of each transaction as the reference point. The RCPT protocol defines the data and system architecture that allows businesses to integrate and process data to the RECEIPTIUM Network. This trust protocol is governed by the RCPT Utility Token. The RECEIPTIUM Identity Protocol (RiDP) also allows the consumers to maintain and control their data and privacy in accordance with the relevant local Data Protection legislations.
