Abstract
After NFC transaction information is sent from the first device to the second device via the NFC protocol, the second device sends the NFC transaction information to the third-party. Both the first device and the third-party compute the same transaction identifier utilizing the NFC transaction information, and both the first device and the third-party register with a host server utilizing this transaction identifier. The first device may then send a public key to the host server with the transaction identifier, and the host server may send the public key to the third-party. The third-party may encrypt a document using the public key and may send the encrypted document to the host server with the transaction identifier. The host server may then send the encrypted document to the first device, where the first device may decrypt and present/store the decrypted document.
