Big Drop Inc carries a solid portfolio in e-commerce design and online marketing. This New York City-based company works exclusively with local merchants who have great ambitions for commercial operations on the World Wide Web. On the back end, several types of scripts and codes have to be deployed to support complex operations that involve product displays and payment processing. For example, PHP is a versatile syntax that supports the framework of data-driven content. SQL and MySQL should also be used to control databases that store information on products and digital items for sale. Big Drop Inc makes sure that e-commerce websites comply with the most recent guidelines of the Payment Card Industry Data Security Standard. Google Wallet, Apple Pay and PayPal are some payment solutions that are compatible with this important industry standard. Additionally, First Data, Braintree and Authorize.net can be used to collect money from credit cards and debit cards.
