TikTok's new shopping platform, a competitor to Amazon.com Inc. (NASDAQ:AMZN), is raising concerns about product authenticity and data security. Many products on the platform come from China, and there are issues with product choices and brand names. Despite these concerns, TikTok Shop's daily consumer spending has risen from $500,000-$1 million in June to $3-$4 million currently, and is expected to surpass $10 million by year-end.
