Multiple card data breaches in the retail industry demonstrate the importance of payment application security. Existing magnetic stripe data (MSD) card payment technology, which was created several decades ago, is highly vulnerable by design. In order to protect cardholder data, many merchants follow Payment Card Industry Data Security Standards (PCI DSS). However, security controls prescribed by PCI DSS are not effective in many situations. Extra measures, such as encrypting the sensitive card data “end to end,” are required in order to provide an adequate level of security and protect the payment transactions from fraud. The HP Mobile POS solution enables hardware encryption of sensitive cardholder data at the entry point which allows merchants to implement a point-to-point encryption (P2PE) solution.
