Method and apparatus for providing real time mutable credit card information and for providing sleep mode functionality

A method for using a smartcard, the smartcard comprises a microprocessor chip, a button, a dynamic transaction authorization number, a Bluetooth low energy (“BLE”) device, a battery configured to power the BLE and the microprocessor chip, memory configured to store the dynamic transaction authorization number, a dynamic magnetic strip comprising a digital representation of the dynamic transaction authorization number, the method comprising:

• transmitting, upon depression of the button, an instruction to a smartphone for a request for an updated dynamic transaction authorization number;
• receiving the updated dynamic transaction authorization number from the smartphone;
• entering a sleep mode, by the smartcard, after a predetermined time period of inactivity by the smartcard.

A system for changing smartcard information on one or more smartcards comprising a microprocessor chip, a button, a dynamic transaction authorization number, a Bluetooth low energy (“BLE”) device, a battery configured to power the BLE and the microprocessor chip, memory configured to store the dynamic transaction authorization number, a dynamic magnetic strip comprising a digital representation of the dynamic transaction authorization number, a sleep mode, the system comprising:

• an administrative database network in communication with a plurality of smartcards, via applications on a plurality of smartphones;
• the administrative database network configured to transmit discrete dynamic transaction authorization numbers to one or more of the smartcards, the transmission being instructive to the smartcard to change the digital representation on the dynamic magnetic strip based on the transmitted discrete dynamic transaction authorization number;
• the smartcard being configured to enter the sleep mode after a predetermined period of inactivity.
