A system comprising:

• a processor in a receiving device comprising a consumer mobile phone configured for receiving documents,
• a tangible, non-transitory memory configured to communicate with the processor,
• the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising:
• creating, by the processor, a digital folder based on an expense classification in a file management system;
• generating, by the processor, a key for a transaction, wherein the key comprises a randomly generated number configured to guard the digital folder;
• transmitting, by the processor, the randomly generated number to the file management system;
• instructing, by the processor and in response to the generating the key, the file management system to instruct a merchant point-of-sale transmitting device to transmit a document to the digital folder, wherein the document comprises a receipt for the transaction;
• displaying, by the processor, the key on a display of the receiving device;
• wherein the point-of-sale transmitting device optically scans the key from the display of the receiving device;
• wherein, in response to the merchant point-of-sale transmitting device scanning the key on the display of the receiving device, the merchant point-of-sale transmitting device is configured to transmit the document to the digital folder based on an expense classification of the document matching the expense classification of the digital folder;
• transmitting, by the processor, a request to access the document to the file management system, wherein the request includes the randomly generated number;
• and
• displaying, by the processor, the document on a screen of the receiving device.

An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a computer-based system configured for transmitting information between devices, cause the computer-based system to perform operations comprising:

• creating, by a receiving device comprising a consumer mobile phone, a digital folder based on an expense classification in a file management system;
• generating, by the receiving device, a key for a transaction, wherein the key comprises a randomly generated number configured to guard the digital folder;
• transmitting, by the receiving device, the randomly generated number to the file management system;
• instructing, by the receiving device and in response to the generating the key, the file management system to instruct a merchant point-of-sale transmitting device to transmit a document to the digital folder, wherein the document comprises a receipt for the transaction;
• displaying, by the receiving device, the key on a display of the receiving device;
• wherein the point-of-sale transmitting device optically scans the key from the display of the receiving device;
• wherein, in response to the merchant point-of-sale transmitting device scanning the key on the display of the receiving device, the merchant point-of-sale transmitting device is configured to transmit the document to the digital folder based on an expense classification of the document matching the expense classification of the digital folder;
• transmitting, by the receiving device, a request to access the document to the file management system, wherein the request includes the randomly generated number;
• and
• displaying, by the receiving device, the document on a screen of the receiving device.
