According to the report, customers are concerned about releasing credit card details online, the lack of opportunity to check goods before paying and the risk of fraudulent suppliers.
The report also revealed that Internet users are more worried about shopping online than people who do not use the Internet. While almost 35% of adults think the Internet is the most risky place to shop, among Internet users this figure is over 50%.
Alison Hopkins, senior policy officer at NCC, who took part in discussion groups for the report, said that what came through in the study was that consumers, even consumers who knew about security and encryption, were uneasy about online shopping.
"It was as if they didn't have confidence in their own knowledge. They never quite trusted that they were going to get what they had asked for until it arrived," she said.
A spokeswoman for flight company EasyJet, which now sells 70% of its seats online, said that she could understand how people were concerned when Internet businesses first started, but thought that people were becoming more confident about shopping online.
She suggested this had a lot to do with people becoming more confident in the specific businesses they were buying from.
