The article mentions that Food Link and Giant (both part of Ahold Delhaize USA) are two supermarkets that responded to the ACLU survey saying that they do not use face recognition. I searched around and found the more complete list of companies' responses: https://www.aclu.org/blog/privacy-technology/surveillance-te... (near the bottom). The tl;dr though is that most companies refused to answer.
