Method and system for a seamless transition between a smaller sized display and a larger sized display during purchasing interactions

A computerized method for providing a seamless transition between a first device with a first display size and a second device with a second display size during a purchasing transaction comprising:

• receiving, by a transaction server, authentication information of a user from a first device, wherein the transaction server is accessible to a data storage unit and the first device via a communications network;
• storing, by the transaction server, the authentication information;
• receiving, by the transaction server, a potential authentication information from the user captured by a second device, for comparison of the potential authentication information to the authentication information stored in the data storage unit;
• determining, by the transaction server, the potential authentication information matches the authentication information stored in the data storage unit;
• transmitting, by the transaction server, a response to the second device in response to the determining;
• and
• in response to the transmitted response being a successful verification of the potential authentication information, receiving, by the transaction server, a transaction request from the first device to complete the purchasing transaction at the transaction server.

A computerized method for providing a seamless transition between a first device with a first display size and a second device with a second display size during a purchasing transaction comprising:

• instantiating a set of computer executable instructions on the first device in response to receiving the set of computer executable instructions;
• interacting, executing the set of computer executable instructions by a processor on the first device, with the user on the first device to receive authentication information;
• transmitting, by the processor of the first device, the received authentication information to a transaction server, said transaction server being remote with respect to the first device;
• storing a first session information on the first device;
• receiving a data packet on the first device, said data packet including a second session information, said second session information including information of a state of a purchasing interaction;
• based on the second session information, restoring the state of purchasing interaction on the first device in the instantiated set of computer executable instructions;
• and
• transmitting a transaction request from the first device to the transaction server to complete the purchasing interaction.
