Abstract: Technology is described for storing and reading a data file using a token encoded in a printed optical code. The method can include receiving the data file over a computer network from a client device. The data file can be sent to be stored in a data store of virtualized data storage accessible via the internet. A token may be received from the data store and the token can be used to access the data file. The data file is returned from the data store when the token is later received from a client device. The token is encoded into an optical code. The optical code can be sent to the client device, where the client device has access to a printer to print the optical code with the token encoded. Any electronic copy of the token can be destroyed.
