For years, ATM owners have relied on expensive and risky manual installation of encryption keys. The traditional method relies on two technicians, each carrying a portion of the secret code, to enter the code into each and every machine in a portfolio.
Susceptibility to fraud and error are two of the drawbacks to this method, not to mention the cost. Of course, regulatory mandates for remote key loading (RKL) are on the horizon as well. Version 1.2 of the Payment Card Industry Council Data Security Standard requires keys to be changed every 12 months. Updating keys manually every year could turn into an expensive, time-consuming proposition.
