Abstract: Systems and methods for IMS telephony enabled information exchange are disclosed. In some implementations, a transfer request to transfer a file from a first user to a second user is received at a IMS gateway and during an ongoing telephone call established between a first device associated with the first user and a second device associated with the second user. The second user on the ongoing telephone call is identified at the IMS gateway. Upon identifying the second user and responsive to the transfer request, the file is transferred from the first user to the second user.

Abstract: A computing device may receive account information identifying a user account and may authenticate the computing device as authorized to configure pre-authorized transactions for the identified user account. The computing device may receive pre-authorization parameters specifying limitations on transactions to be performed using a payment card associated with the user account, the limitations being separate from limitations on use of the payment card specified in a cardholder agreement associated with the payment card, and may provide a pre-authorization request to a transaction authorization server authorizing transactions performed using the payment card, the pre-authorization request including the account information and the pre-authorization parameters.
