长宁推广餐饮“一码通识” - 2020年07月15日

A QR code allowing customers to find basic information about catering businesses is being trialed in Changning District, authorities announced on Tuesday.
By scanning the code, consumers can access bilingual information about staff and licensing, ingredients and how they deal with kitchen waste oil and make comments, the Shanghai Greenery and Public Sanitation Bureau said.
At the same time, collection workers can record the type and amount of waste oil they collect using the code, the bureau said.
