Raul owns a small shop that sells sports gear with a special focus on outdoor sports like bicycling, hiking, and kayaking. He has a small website, but it doesn't yet support online purchases. He's decided to expand his business by targeting a larger geographical region, and that means his website needs extensive upgrades. Raul is concerned, though, about what kinds of regulations he will have to meet in order to handle online transactions and customer payment information. Research basic PCI requirements for small businesses. Who do these standards apply to? What are the cutoff points for each level of compliance requirements according to number of transactions per year?
