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 device (100; 100a) has a processing device (110), a user interface (120), and a short-range wireless communication transceiver (130). The short- range wireless communication transceiver (130) is configured for receiving a short- range wireless communication signal (S) from another communication device (100b). The processing device (110) is configured for reading a communication identifier (CI) of the received short-range wireless communication signal (S), determining - based on the communication identifier (CI) - a particular audio/visual/audiovisual media content (140a) among a plurality of possible media contents (140), controlling the user interface (120) to present the particular media content (140a) to a user (1a) of the communication device (100; 100a), and controlling the user interface (120) to receive an input (INP) from the user (1a).

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).

Abstract: A method for improving the ability to detect passive beacon receiver devices is disclosed. According to the method, a beacon communication system which comprises one or more short-range wireless beacon transmitter devices, at least one of which is configured to repeatedly transmit a short-range wireless beacon advertisement signal on a first beacon broadcast channel, is operated by causing a device among the short-range wireless beacon transmitter devices to temporarily transmit a short-range wireless beacon refresh signal on a second beacon broadcast channel. The beacon refresh signal is adapted to cause one or more short-range wireless beacon receiver devices being in a passive mode to enter into a short-range wireless beacon scanning mode.

Abstract: Asset authentication in a dynamic, proximity-based network of communication devices, each having a first interface for establishing the dynamic, proximity-based network by short-range wireless beacon broadcast messaging, and a second interface for communicating with a server by broadband communication. A first communication device sends (210) via the first interface an authentication request to a second communication device having an associated asset. The second device receives (220) the authentication request via the first interface and in response communicates (230) with the server via the second interface to generate a digital signature by encrypting data which includes the asset with a private key for the second device. The second device sends (240) a signing completed report message about the generation of the digital signature to the first device via the first interface.

Abstract: A method is provided for establishing a dynamic, proximity-based group of wireless communication devices to support potential interaction between a user of a first wireless communication device and one or more users of the wireless communication devices in the dynamic, proximity-based group. In the method, the first wireless communication device sends a short-range wireless beacon broadcast message to other wireless communication devices in a proximity zone around the first wireless communication device. The short-range wireless beacon broadcast message is adapted for requesting the other wireless communication devices to send a response message to a server. The server registers responding devices among the other wireless communication devices.
