Multi-path communication of electronic device secure element data for online payments

A method comprising:

• receiving, by a device and from a first subsystem via an online resource, potential transaction data;
• generating, on a secure element of the device, secure cryptographic data using at least a portion of token data and a shared secret between the device and a second subsystem;
• transmitting, to a third subsystem, device transaction data that comprises the secure cryptographic data;
• receiving, from the third subsystem, first subsystem data that comprises a transaction identifier associated with the device transaction data;
• and
• transmitting, to the first subsystem via the online resource, second another first subsystem data that comprises the transaction identifier and the token data.

A non-transitory machine-readable medium comprising instructions that, when executed by one or more processors of a device, cause the one or more processors to perform operations comprising:

• receiving, by the device and from a first subsystem via an online resource, potential transaction data;
• generating, on a secure element of the device, secure cryptographic data using at least a portion of token data and a shared secret between the device and a second subsystem;
• transmitting, to a third subsystem, device transaction data that comprises the secure cryptographic data;
• receiving, from the third subsystem, first subsystem data that comprises a transaction identifier associated with the device transaction data;
• and
• transmitting, to the first subsystem via the online resource, another first subsystem data that comprises the transaction identifier and the token data.
