1. A method of using a universal card in a proxy card transaction, the method comprising:
receiving, by a computing device, a request to use a universal card as a proxy card and a selection of a selected account, wherein the computing device comprises a first processor, a first memory, a first power source, a first user interface, a first short range transceiver, and an e-wallet application executable by the first processor; and wherein the universal card comprises a second power source, a second processor, a second memory, a second short range transceiver, a dynamic data communication mechanism including a dynamic magnetic stripe, and a secure element; generating, by the computing device, proxy card data comprising an indication of the proxy card and an indication of the selected account; transmitting, from the computing device to a proxy card server, the proxy card data; transmitting, from the computing device to the universal card using the first and second short range transceivers, the proxy card data; and emulating a static data communication mechanism of a proxy card by configuring the dynamic data communication mechanism of the universal card using at least a portion of data stored in the secure element; wherein the static data communication mechanism of the proxy card is emulated by writing data indicative of the proxy card to one or more required fields of the dynamic magnetic stripe and by writing an indication of the selected account to one or more discretionary data field of the dynamic magnetic stripe; and wherein the dynamic data communication mechanism of the universal card passes data indicative of the proxy card and the selected account to a terminal during a transaction with the terminal. |
