On 4 October 2007,  The National Retail Federation (NRF) Chief Information Officer and Senior Vice President, David Hogan wrote a letter to the Payment Card Industry (PCI) Standards Council requesting that the card industry to stop requiring merchants to store complete card numbers. Currently, some merchants are required to keep credit card numbers for up to 18 months to satisfy card retrieval and dispute requests. The letter said, “"Instead of making the industry jump through hoops to create an impenetrable fortress, retailers want to eliminate the incentive for hackers to break into their systems in the first place." NRF proposes that credit card companies and their banks should provide merchants with the option of keeping nothing more than the authorization code provided at the time of sale and a truncated receipt, rather than requiring merchants to keep the data for an extended amount of time.
