METI Conducts Experiment for Examination of Standard Specification of Digital Shopping Receipts

Standard specification of purchase history data and API formulated

June 29, 2018

From February 13 to 28, 2018, the Ministry of Economy, Trade and Industry (METI) conducted an experiment examining a standard specification for digitized shopping receipts (digital receipts)* in Machida City, Tokyo. After the experimental examination, nearly 90% of participating consumers answered that they would like to continue to receive their shopping receipts digitally. This results helped METI to ascertain the public need to improve shopping convenience through the use of digital receipts, and to formulate an official standard for purchase history data and APIs.**

METI will further strive to advance the development of environments under which businesses are able to efficiently and effectively make use of individual-sourced consumer purchase history data.

2. Results of the experiment

In the experiment, the following matters were examined:

The results of this experiment discovered that participating stores in a variety of industries successfully issued digital receipts under the test standard specification to 815 participating consumers. Moreover, making use of the test API, 790 consumers succeeded in connecting their data to the data pool, while 248 consumers in total succeeded in establishing a connection to other smartphone applications.

In addition, METI conducted a questionnaire for the participating consumers and found in the responses that nearly 90% consumers would like to continue to receive their shopping receipts digitally and that nearly 70% consumers would like to use stores issuing digital receipts under a standard specification if they can.

3. Formulation of an official standard specification and AIP

Through this experiment, METI successfully demonstrated that stores in a variety of industries are able to issue digital receipts under a standard specification, and that consumers are able to integrate and manage their data on digital receipts and connect the data to other applications using an API through their own provision of such data. In addition, METI modified the test standard specification based on the results of the experiment and went on to formulate an official standard specification and API for purchase history data.

METI will further strive to advance the development of environments under which businesses are able to efficiently and effectively make use of individual-sourced consumer purchase history data by developing use cases of companies that have adopted the standard specification that METI formulated.
