"This guide describes the problem of check and card fraud, and reviews factors that increase the risks of it. It then identifies a series of questions to help you analyze your local problem. Finally, it reviews responses to the problem, and what is known about them from evaluative research and police practice. The guide covers fraud involving all types of checks and plastic cards, including debit, charge, credit, and "smart" cards. Each can involve a different payment method . While there are some obvious differences between check and card fraud, the limitations and opportunities for fraud and its prevention and control by local police are similar enough to warrant addressing them together. Furthermore, some cards (e.g., debit cards) are used and processed in a similar way to checks, and electronic checks are processed in a similar way to cards, so that the traditional distinction between cards and checks is fast eroding. Table 1 summarizes the essential differences between check and card fraud."
