  • Service Provider company or organization in charge of providing services for at least one of the parties involved in this business.
  • the POS device was a manual reader which copied the information contained in cards into a sheet. Such sheets were used in financial settlement operations (last financial operation of the transaction, the money transfer from the issuer bank of the card to the seller/establishment).
  • the authorization operation was performed at the purchase, when the seller/establishment checked the validity of the card information in different ways: by comparing the information present in the card with that of ID documents, comparing the signature on the back of the card with the signature presented or calling to confirm the information and the balance.
  • the operations of authorization and settlement have become electronic and the POS device has gained the function of interconnecting with acquirers to process the authorization during the transaction.
  • the paradigm shift to the electronic processing of the authorization and settlement reduced the transaction execution time and increased the system security, becoming indispensable for the functioning of the market.

  • the communication method through fallback link described in this second embodiment is analogous to the previously described method in that a main POS device performs transactions through a second neighboring POS device.

  • Figure 15 shows this case of fallback link.
  • a main POS device 1 temporarily without communication with third network 8a, communicates with either an acquirer 12a or a service provider 12b through the computer 4c and the third network 8b.

  • the devices of the communication system act as intermediate elements of the communication, forwarding the messages between the main POS device and either the acquirer or the service provider. Accordingly, the following communication method through fallback link is proposed:
  • the main POS device Upon loss of connection with an acquirer or a service provider, the main POS device searches the best-classified neighboring device among its neighboring devices of the communication system in order to forward the message. As mentioned above, the classification of the neighboring devices is based on several criteria. The selected neighboring device receives the message and forwards it according to the classification of its neighboring devices or forwards it directly to the acquirer or the service provider through a third network. Each device receiving the message follows these steps and the message is forwarded by multiple jumps to the acquirer or service provider.
  • a main POS device 1 upon loss of connection with either the acquirer 12a or the service provider 12b through the third network 8a, a main POS device 1 connects with them, through multiple devices of the communication system 3 and of the third network 8a, 8b.
  • Each message exchanged between the main POS device 1 and either the acquirer 12a or the service provider 12b does not necessarily follows the same path in the communication system 3. As it was previously described, the path the message has to follow is decided jump by jump, wherein the device receiving the message chooses its better-classified neighboring device to reach the destination and forwards said message to this neighboring device.
  • the embodiments are not mutually exclusive, allowing the same POS device to communicate with either the acquirer or the service provider through fallback links, through any type of neighboring device. This aims at decreasing the chances of failure in the transaction due to network unavailability.
  • the present invention makes provides a seller/establishment to choose to communicate through fallback link. This option makes the communication through fallback link a standard in the communication with either the acquirer or the service provider.
  • POS devices of the installed system of an acquirer should have their applications constantly updated.
  • the acquirer notifies the POS device whether it requires updating.
  • the POS device Upon receipt of the notification, the POS device connects to an update server at the time and date informed in the notification.
  • update server at the time and date informed in the notification.
  • the POS devices can benefit from the exchange of messages with other neighboring devices, as proposed in the present invention, in order to decrease the number of accesses to the acquirer. Accordingly, a method for updating the applications of POS devices is proposed and described as follows.
  • the acquirer or some neighboring devices warn a main POS device that it requires updates. Thus, it exchanges messages with its neighboring devices in order to check if any of them have already been updated. If one of the neighboring devices already has been updated, the main POS device requests the update from this neighboring device which transmits said update.
  • the update is divided into parts, herein referred to as packets, which can be transmitted independently. If none of the neighboring device has been updated, the main POS device requests the acquirer to be updated directly. Upon receipt of the entire first packet, the main POS device requests the acquirer 12a or some neighboring device to send the next packet and, thus, successively until all the update is received.
  • the main POS device sends a control message to its neighboring devices, notifying that a new update packet is available to be sent. Upon request from a neighboring device, then the main POS device transmits the update packet. If the neighboring POS device does not obtain the update packet from the main POS device, the neighboring POS device can connect with either the acquirer 12a or the service provider 12b in order to obtain said update packet.
  • Figure 18 shows a POS device 1 receiving an update 18 from its acquirer 12a.
  • the update 18 is divided into four parts, 18a, 18b, 18c and 18d, and each part is sent to the POS device 1 through messages 19.
  • the POS device 1 has already the first part of the update 18a and an acquirer 12a sends the second part 18b through a message 19.
  • the POS device 1 recognizes that its neighboring devices also need the update 18 and that they have not received the first part 18a of said update yet. Therefore, the POS device 1 sends the first part of the update 18a to its neighboring devices. The foregoing process can be performed until all the devices receive the complete update.
  • the POS device 1 also comprises a memory 190, wherein the update packets 18a, already received, are stored.
  • the POS device 1 upon receiving the first packet, notifies its neighboring devices that a new packet is available. In the notification, the POS device 1 informs a time and date schedule when the neighboring devices should connect with the POS device 1 to get the update packet.
  • the POS device 1 upon receiving the first packet, notifies its neighboring devices that a new packet is available.
  • the neighboring devices connect with the POS device 1 and require the new packet.
  • the POS device 1 replies with a schedule message informing the time and date when the neighboring devices should connect and receive the packet.
