Abstract: A method of transferring digital cash comprises establishing (20) a local point-to-point communication link (CL) directly between a mobile communication device (MCD) and a smart card (SC) upon being in proximity of each other (10), then communicating (30) cash transfer data (CTD) over the local point-to-point communication link (CL). The cash transfer data (CTD) defines a local transfer of a monetary amount (Amount) from one of the mobile communication device (MCD) and the smart card (SC), being a cash sender, to the other of the mobile communication device (MCD) and the smart card (SC), being a cash receiver. The method further comprises updating (40) a balance (balance_ow) of a local digital wallet (OW) of the mobile communication device (MCD) as well as a balance (balance_card) of the cash deposit (CD) to reflect the local transfer of the monetary amount (Amount), such that the balance of the cash sender is reduced while the balance of the cash receiver is increased.

Abstract: A computerized method (100) of performing a digital payment of a payment amount (Amount) between a payer (P1) and a payee (P2) provides payment service provider interoperability. A payer communication device (PD1) and a payee 5 communication device (PD2) communicate (112) by short-range data communication during an offline settlement stage (110) to generate payment transaction data (Transaction Data) being digitally signed (114) by the payer communication device (PD1). The generated payment transaction data (Transaction Data) is validated (116) by the payee communication device (PD2).

Abstract: A communication system (100) comprises a thin-client mobile terminal (MT) having a device identity (MT_ID), a thin-client service terminal (ST), and a remote system server resource (SS). The thin-client mobile terminal (MT) is configured for receiving (101) from the service terminal (ST) a short-range wireless communication signal (BA) representing an identification request (ID_REQ), and in response communicating (102) with the remote server resource (SS) by long-range broadband data communication to report the identification request (ID_REQ) as well as the device identity (MT_ID) of the mobile terminal (MT).

Abstract: A method (600) for handling a digital payment between a payer (P1) and a payee (P2) is presented. The payer and payee communication devices (PD1, PD2) uses (610) short-range data communication (SRDC) when the devices are in proximity of each other to agree upon a digital payment (DP) without requiring long-range data communication with a remote digital payment settlement service (DPSS) at that stage. Independently of the other device, the payer communication device (PD1) or the payee communication device (PD2) subsequently communicates (630) buffered digital payment information (DPI) to the remote digital payment settlement service (DPSS) by long-range data communication (LRDC1, 15 LRDC2). The remote digital payment settlement service (DPSS) causes settlement (640) of the digital payment (DP) as indicated by the digital payment information (DPI) received by long-range data communication (LRDC1, LRDC2) from one of the payer communi-cation device and the payee communication device (PD1, PD2).
