A methods and system of hosted thin-client payment authorization and authentication services for processing payments for value-added service (VAS) providers is described. A method, performed by a host server operating a thin-client device, includes receiving transaction request data at a host server computer from a thin-client device, where the transaction request data can include financial account data and biometric data. The host-server transmits a verification request message to a VAS provider and receives an indication that it is a valid merchant. The host-server transmits an authorization request message comprising the biometric data to a payment processing network (PPN), where the PPN communicates with an authentication server computer to validate the biometric data, sends the authorization request message to an issuer and receives an authorization response message from the issuer. The host-server receives the authorization response message from the PPN and sends a service fulfillment request to the VAS provider.
