Method for transferring a file via a mobile device and mobile device for performing same
View Patent ↗A mobile device, such as a cellular phone, can transfer an encrypted file from a server to a terminal, such as an automated teller machine. The server can specify delivery to a specific terminal. The mobile device can download an encrypted file and identity metadata from at least one server. The mobile device can connect to a terminal, such as wirelessly or via a wired connection such as a universal serial bus (USB). The mobile device can match an identity of the terminal to an identity associated with the identity metadata. For a USB connection, the identity metadata can include a vendor identifier (VID), a product identifier (PID), and a unique terminal identifier. If the identities match, then the mobile device can upload the encrypted file to the terminal. If the identities do not match, then the mobile device can prevent the encrypted file from uploading to the terminal.
