Abstract: A system for a secure cardholder and storage device includes a mobile communication device and a secure card transporter (SCT). The SCT includes a Near Field Communication (NFC) chip, a microprocessor, a magnetic stripe card reader, a contact chip card reader, a contactless card reader, an audio jack interface and a micro-USB interface. The SCT interfaces with the mobile communication device via the audio jack interface or the micro-USB interface, and the SCT captures payment card data and transmits the captured payment card data to a merchant point of sale (POS) checkout system both in the physical and virtual environments. The system provides convenient buying experience for buyers, and secure and informative transaction for sellers.
