Title: Method and system to activate a mode of a service station

Description:
FIELD OF INVENTION 
     Embodiments of the present invention relate to a method and system to activate a mode of a service station. 
     BACKGROUND 
     Provision of short-term accommodation (by hotels and accommodation facilitators like Airbnb™) has traditionally been charged on a per-day basis. The chargeable rate typically remains constant regardless of the amount of electricity consumed by the customer during their stay. In order to increase revenue and encourage more efficient use of electricity in their premises, it would also be desirable to be able to introduce some control of the usage of electrical appliances provided in the room for the guest by charging guests for their usage of those appliances. 
     In addition, self-service machine manufacturers such as manufacturers of commercial washing machines and dryers, event or gymnasium lockers, or parking ticket machines typically provide for payment by coin or credit card, particularly machines which have been in use or conceived before smartphones were popular. If one did not have the correct denomination of coins, sufficient money or a credit card then payment and use of the self-service machine may not be possible. This leads to inconvenience for the consumer and loss of business for the machine operator/owner. It would be desirable to allow the consumer to use a self-service machine without requiring coins or a physical credit card to be presented to the machine. 
     It is also generally desirable to improve consumer experiences with making payments for goods and services.

     DETAILED DESCRIPTION 
     There is provided a method, and system for making payment to activate a mode of a service station. In at least some embodiments, the method, and system allow users to activate a mode of a service station where in the past, there would be issues doing so, due to for example, lack of change, lack of credit card, and so forth. In addition, the method, and system may lead to enhanced revenues at the service stations as well as improved user experiences when making payments at service stations. 
     An example of a method for making payment to activate a mode of a service station will now be described with reference to  FIG. 1 . 
     For the purpose of illustration, it is assumed that the method is performed at least in part using one or more electronic processing devices such as a suitably programmed microcontroller forming part of an authentication device and in communication with one or more user devices, such as mobile phones, portable computers, tablet computers, or the like. The user devices are also typically in communication with a payment system which may comprise any suitable computer system such as a server that is capable of processing payments made by the user and which may include a number of processing devices associated with each of an issuer, acquirer, card network and payment gateway, or alternatively, the payment processing system may include any one or more of these entities and this will be discussed further below. 
     The term service station is intended to cover any electrical device that consumes power and will typically refer to consumer appliances such as washing machines, dryers, phone or battery chargers, televisions, lamps, fridges, dishwashers, heaters and the like, although commercial machines such as vending machines, ticketing machines, parking meters and the like may also be included. 
     In this example, at step  100  the one or more electronic processing devices provide a service token to a user device, the service token being indicative of one or more pre-selected payment options associated with activating a mode of the service station, and/or also associated with a service session established between the user device and the service station. The payment options associated with a particular appliance will typically have been pre-selected by a merchant who may be the manufacturer or operator/owner of the service station. The payment options will typically be of different payment quantums specific for the service station and the functionality that it provides. For example, a washing machine or dishwasher may provide multiple payment options for particular wash cycles or durations whilst a phone charger may simply provide a single payment option to fully charge a mobile phone. Whilst typically a user will pay to power an appliance for a given period of time, in alternative examples, the user may pay for a pre-determined amount of power or pay for the use of the appliance for a specific purpose such as charging a phone (which would not necessarily be based on time). 
     Typically, the one or more electronic processing devices communicate with the user device to provide the service token via a wireless communications protocol such as Bluetooth, Zigbee, Wi-fi and the like. In one example, the authentication device includes a wireless transceiver such as a Bluetooth™ Low Energy (BLE) module. In one example, the electronic processing device is configured to provide a wireless hotspot to which the user device may be connected or paired. When the user comes within a certain vicinity of the authentication device they will be able to connect or pair with the authentication device in order to establish communication therewith. 
     Having received the service token, the user device is typically responsive to provide the service token to a payment system via a communications network. The payment system is able to interpret the service token to determine the payment options that are associated with the service token for the specific service station. This information will have previously been provided to the payment system from the merchant/owner/operator when configuring the authentication device before use, as will be described in more detail below. 
     The user device then receives from the payment system an indication of the payment options associated with the service token. For example, the payment system may cause a user interface such as payment webpage to be displayed on the user device which provides a representation of the payment options (such as $1.00 for 3 minutes, $2.00 for 6 minutes and so forth). The user then selects a desired payment option for example by clicking on a button indicative of the payment option and proceeds to checkout to pay for the use of the service station. In this way, the user provides payment information to the payment system in accordance with the payment option selected by the user. The transaction may then be processed in a similar way to which a standard e-commerce transaction is performed with a merchant/owner/operator. In response to successful payment using the provided payment information, the user device then receives a payment token from the payment system. 
     At step  110 , the one or more electronic processing devices then receive the payment token from the user device. In this regard, the same wireless communication protocol previously described is used by the user device to send the payment token to the authentication device. In this regard, after receiving the payment token from the payment system, the user may be prompted through a user interface or via a message to send the payment token to the authentication device. 
     At step  120 , the one or more electronic processing devices then use the payment token to control the service station at least partially in accordance with the payment option selected by the user. In this regard, the payment token will be indicative of the payment option selected by the user and the authentication device will be able to interpret the payment token to control the service station in accordance with the selected payment option as will be described in further detail below. 
     Thus, once the payment token has been received, the authentication device can cause the service station to operate in a desired manner (mode). In this regard, it will be appreciated that the authentication device can be located between a power supply and the service station such that the authentication device is operable to cause the service station to operate in a desired manner (mode). As will be described in more detail later, in one example the authentication device forms parts of or comprises an adaptor which may be located between a power outlet and the service station. Alternatively, the authentication device may be embedded into the power outlet such than the service station can be plugged directly into a wall outlet for example, or could be incorporated into the service station. 
     The above described method and apparatus provides a number of advantages. 
     Firstly, the method enables the service station to be used on a ‘pay per use’ basis without requiring any physical coins, bank notes banks cards to be presented for payment. This overcomes many of the drawbacks of using commercial self-service machines such as washing machines and dryers which typically require specific denominations of coins for use that a user might not always have. This simplicity of payment may therefore lead to increased uptake and use of such machines leading to increased sales and profitability for machine owners/operators. 
     Enabling service stations to be operated on a ‘pay per use’ basis also provides accommodation suppliers such as hotels and Airbnb™ room owners the opportunity to create an additional revenue stream from use of appliances provided in their rooms for the use of guests. 
     Furthermore, ‘pay per use’ service stations may assist in reducing energy usage by encouraging users to become more conscious of the amount of electricity that they use, particularly when they learn to correlate use of a service station with a specific cost. This may be more readily achieved by paying each time a service station is used rather than paying an overall energy bill for a property on a periodic basis such as monthly/bi-monthly/quarterly as is typically the case at present. 
     A number of further features will now be described. 
     As previously mentioned the one or more payment options may be associated with various parameters. In one example, the payment options are associated with providing power to the service station for a pre-determined amount of time. In this example the user pays for use of the service station for a certain duration of time, typically defined in minutes or hours of usage (e.g. $1.00 to park a vehicle for 5 minutes, $2.00 to park a vehicle for 10 minutes). In another example, the payment options are associated with payment quantums (e.g. $1.50 for a type A canned drink, $3.00 for a type B canned drink). In yet a further example, the payment options are associated with providing an amount of power to the service station in accordance with an electrical parameter of the service station. For example, an electrical parameter could be the state of charge of a battery and the user pays to fully charge the battery which may be associated with a mobile phone or computer for example. The state of charge may be monitored directly or inferred based on a different parameter such as the current drawn by the service station for example. 
     In one example, the one or more electronic processing devices communicate with the user device via a wireless communication protocol as previously mentioned. In one example, the wireless communications protocol includes Bluetooth™ Low Energy (BLE) protocol however any other suitable protocol or form of wireless communication may be used including Wi-Fi, Zigbee or Near Field Communication (NFC). 
     Typically, the one or more electronic processing devices validate the payment token using a device identifier. The validation step typically occurs after the authentication device has received the payment token from the user device and prior to initiating control of the service station to operate the service station in a desired manner (mode). 
     The step of validating the payment token using the device identifier may include a number of aspects. For instance, the payment token generated by the payment system may be encrypted using a key derived from or associated with the device identifier. In this case, part of the validation step would include decrypting the payment token using the key derived from or associated with the device identifier. In this way, the device identifier may be used to determine that the payment token has been received by the intended authentication device, as well as to ensure the payment token is a legitimate payment token generated by the payment system. A further validation step may include determining that the payment option selected by the user (and associated with the payment token) is valid for the particular service station. The step of validating the payment token may therefore ensure that the payment token has not been inadvertently sent or received by an incorrect service station, and that a payment option that is actually provided is desired by the user. 
     Typically, before the authentication device is ready to be used by a user, it is set up by a merchant/owner/operator in order to provide the pre-selected payment options. The payment options can be stored at the authentication device only, a remote server only, or both the remote server and a merchant device. In this regard, the one or more electronic processing devices typically communicate with the merchant device via a wireless communications protocol in order to pre-configure the authentication device prior to use by the user. The authentication device may communicate with the merchant device via any of the wireless communications protocols previously discussed that may be used to communicate with the user device. It is also possible for the authentication device to be configured for wired communications using protocols such as, for example, Ethernet, serial, I2C, UART, SPI and so forth. The authentication device can be coupled to a merchant-dependent secondary device which enables the wired communications, such as, for example, an SD card with a secure element, a personalized smart card, and so forth. 
     An example of a merchant configuration process shall now be described. In this example, the one or more electronic processing devices firstly generate an initialization data packet. The initialization data packet is generated based on the device identifier such as a unique device key or a shared secret data packet assigned to the authentication device by the manufacturer. The initialization data packet is provided to the merchant device in order to configure the authentication device with one or more merchant selected payment options. The merchant device is responsive to the initialization data packet to register the initialization data packet with the one or more payment options associated with providing electrical power to the service station (for example $1.00 for 3 minutes, $2.00 for 6 minutes). In one example, this step may be performed using a merchant application executing on the merchant device or via any other suitable interface that allows the merchant to associate payment options with the initialization data packet. 
     The merchant device then provides the registered initialization data packet to a payment system, the payment system responsive to generate provisioning data for use in controlling the authentication device as will be described in further detail below. The merchant device receives the provisioning data from the payment system and in turn sends the provisioning data to the authentication device. The authentication device receives the provisioning data and stores it in a data store forming part of the authentication device. The provisioning data is used by the authentication device to configure the authentication device, so that the authentication device can at least partially control the service station in accordance with the payment option selected by the user. 
     As previously mentioned, the initialization data packet is generated using a device identifier associated with the authentication device. The device identifier is typically stored in at least one of a local data store and a remote data store (for example associated with the payment system). The local data store typically forms part of the authentication device. The remote data store is remote to the authentication device and may be in communication with the one or more electronic processing devices via a communications network. 
     The provisioning data for use in controlling the switch typically includes at least one of a merchant identifier associated with the merchant/owner/operator, a device identifier associated with the authentication device, an indication of the payment options provided by the merchant associated with providing electrical power to the service station, and instructions for use in controlling the service station in accordance with the payment options. The provisioning data therefore comprises software and/or firmware that is permanently programmed into the read-only memory of the authentication device in accordance with the payment options provided by the merchant/owner/operator. 
     In one example, the one or more electronic processing devices validate the provisioning data prior to storage in the data store. For example, the validation process may include determining that the device key associated with the provisioning data matches the device key of the authentication device to which the provisioning data has been sent. This can be achieved in any suitable manner, such as through encryption of the provisioning data using the device identifier, in a manner similar to that described above with respect to the payment token. Furthermore, the validation process may check whether a valid merchant identifier has been provided to ensure that payment for use of service stations connected to the authentication device are routed to the appropriate merchant/owner/operator. 
     It is to be appreciated that the above described method is performed by one or more electronic processing devices forming part of an authentication apparatus. The apparatus further includes a wireless transceiver module and wherein the one or more electronic processing devices communicate with the user device (and merchant device) via the wireless transceiver module. In a specific form, the wireless transceiver module is a Bluetooth™ Low Energy (BLE) transceiver module, although it need not be limited to such and could include any suitable wireless transceiver. The apparatus may further include a local data store as previously described for storing the provisioning data, device identifier etc. 
     The above components of the apparatus can be housed within a housing that can include a plug for releasable engagement to a wall mounted electrical power outlet, and a socket for receiving an electrical plug associated with the service station. Alternatively, the apparatus may include a switch housing adapted for securement to a wall mounted electrical power outlet. It is to be understood therefore that the apparatus could form either an adaptor that plugs into a wall socket or it may be embedded into the wall socket or power outlet. In either case, the apparatus is capable of providing an interface between an electrical power supply and an appliance. Whilst typically the power supply will be a mains electricity supply, in some examples the power supply may be from a battery or other form of energy storage. The apparatus can also be integrated with the service station in a manner such that the apparatus is communicatively coupled to a controller of the service station and is able to control the service station. 
     In one example, a user application is provided on the user device for use in controlling the authentication device to control the service station in a desired mode. The user device typically includes one or more electronic processing devices to receive a service token from the authentication device, the service token being indicative of one or more pre-selected payment options associated with providing power to the service station. The user device then provides the service token to a payment system via a communications network and receives from the payment system an indication of the payment options associated with the service token. The user then selects a payment option via the application which thereby receives an indication of a payment option selected by the user. The payment information is then provided to the payment system in accordance with the payment option selected by the user and the user device receives a payment token from the payment system in response to successful payment using the provided payment information. Finally, the user processing device provides the payment token to the authentication device, the authentication device responsive to the payment token to control the service station in accordance with the selected payment option. The authentication device validates the payment token using a unique key. 
     An example of a system for making payment to activate a mode of a service station will now be described with reference to  FIG. 2 . 
     In this example, the system  200  includes an authentication device  214  in communication with any of the service stations, for example, a washing machine  210 , a power adaptor  224 , a ticketing machine  222 , a parking metre  218 , and a vending machine  216 . The authentication device  214  is further in communication with one or more user devices  220  optionally running a payment application and one or more merchant devices  230  optionally running a merchant application. The user and merchant devices  220 ,  230  are in communication with a payment system  240  via a communications network  250 . The payment system  240  may be in communication with a database  241 . 
     The communications network  250  can be of any appropriate form, such as the Internet and/or a number of local area networks (LANs). It will be appreciated that the configuration shown in  FIG. 2  is for the purpose of example only, and in practice the user devices  220 , merchant devices  230 , authentication device  214  and payment system  240  can communicate via any appropriate mechanism, such as via wired or wireless connections, including, but not limited to mobile networks, private networks, such as an 802.11 network, the Internet, LANs, WANs, or the like, as well as via direct or point-to-point connections, such as Bluetooth, or the like. Typically, the one or more user and merchant devices  220 ,  230  communicate with the authentication device  214  via a wireless communication protocol such as Bluetooth, Wi-Fi Zigbee, or through Near Field Communication (NFC) but not limited to such. The user and merchant devices  220 ,  230  may typically communicate with the payment system over a mobile network or via the Internet. 
     User Device  220  and Merchant Device  230   
     The user device  220  and merchant device  240  of any of the examples herein may be a handheld computer device such as a smart phone or a PDA such as one manufactured by Apple™, LG™, HTC™, Research In Motion™, or Motorola™. The user device  220  or merchant device  230  may include a mobile computer such as a tablet computer. An exemplary embodiment of a user device  300  is shown in  FIG. 3 . As shown, the device  300  includes the following components in electronic communication via a bus  306 : 
     1. a display  302 ; 
     2. non-volatile memory  303 ; 
     3. random access memory (“RAM”)  304 ; 
     4. N processing components  301 ; 
     5. a transceiver component  305  that includes N transceivers; and 
     6. user controls  307 . 
     Although the components depicted in  FIG. 3  represent physical components,  FIG. 3  is not intended to be a hardware diagram; thus many of the components depicted in  FIG. 3  may be realized by common constructs or distributed among additional physical components. Moreover, it is certainly contemplated that other existing and yet-to-be developed physical components and architectures may be utilized to implement the functional components described with reference to  FIG. 3 . 
     The display  302  generally operates to provide a presentation of content to a user, and may be realized by any of a variety of displays (e.g., CRT, LCD, HDMI, micro-projector and OLED displays). And in general, the non-volatile memory  303  functions to store (e.g., persistently store) data and executable code including code that is associated with the functional components of a browser component and applications, and in one example, a payment application  308  executing on the user device  220  and a merchant application executing on the merchant device  230 . In some embodiments, for example, the non-volatile memory  303  includes bootloader code, modem software, operating system code, file system code, and code to facilitate the implementation of one or more portions of the payment application  308  as well as other components well known to those of ordinary skill in the art that are not depicted for simplicity. 
     In many implementations, the non-volatile memory  303  is realized by flash memory (e.g., NAND or ONENAND memory), but it is certainly contemplated that other memory types may be utilized as well. Although it may be possible to execute the code from the non-volatile memory  303 , the executable code in the non-volatile memory  303  is typically loaded into RAM  304  and executed by one or more of the N processing components  301 . 
     The N processing components  301  in connection with RAM  304  generally operate to execute the instructions stored in non-volatile memory  303  to effectuate the functional components. As one of ordinarily skill in the art will appreciate, the N processing components  301  may include a video processor, modem processor, DSP, graphics processing unit (GPU), and other processing components. 
     The transceiver component  305  includes N transceiver chains, which may be used for communicating with external devices via wireless networks. Each of the N transceiver chains may represent a transceiver associated with a particular communication scheme. For example, each transceiver may correspond to protocols that are specific to local area networks, cellular networks (e.g., a CDMA network, a GPRS network, a UMTS networks), and other types of communication networks. 
     Authentication Device  214   
     A suitable authentication device  214  for use in the system  200  is shown in  FIG. 2 . 
     In this example, the authentication device  214  includes at least one microprocessor  215 , a memory  217  and an external interface  219  interconnected via a bus. In this example the external interface  219  can be utilised by the authentication device  214  when communicating with peripheral devices, such as the user and merchant devices  220 ,  230  Although only a single interface  216  is shown, this is for the purpose of example only, and in practice multiple interfaces using various methods (e.g. Ethernet, serial, USB, wireless, Bluetooth™ Low Energy (BLE), Near Field Communication (NFC), or the like) may be provided. 
     In use, the microprocessor  215  executes instructions in the form of applications software stored in the memory  217  to allow communication with the user device  220 , for example to provide a service token and receive a payment token therefrom, and the merchant device  230 , for example to provide the initialization data packet and receive the provisioning data. The applications software may include one or more software modules, and may be executed in a suitable execution environment, such as an operating system environment, or the like. 
     Accordingly, it will be appreciated that the authentication device  214  may include any suitable processing system, such as any electronic processing device, including a microprocessor, microchip processor, logic gate configuration, firmware optionally associated with implementing logic such as an FPGA (Field Programmable Gate Array), or any other electronic device, system or arrangement. Thus, in one example, the authentication device  214  is a standard processing system such as an Intel Architecture based processing system, which executes software applications stored on non-volatile (e.g., hard disk) storage, although this is not essential. 
     Payment System  240   
     A suitable payment system  240  for use in the system described in anyone of the above examples is shown in  FIG. 4 . 
     In this example, the payment system  240  is a server that includes at least one microprocessor  500 , a memory  501 , an optional input/output device  502 , such as a display, keyboard, touchscreen and the like, and an external interface  503 , interconnected via a bus  504  as shown. In this example the external interface  503  can be utilised for connecting the payment server  240  to peripheral devices, such as user and merchant devices  220 ,  230 , the communication networks  250 , databases  241 , other storage devices, or the like. Although a single external interface  503  is shown, this is for the purpose of example only, and in practice multiple interfaces using various methods (e.g. Ethernet, serial, USB, wireless or the like) may be provided. 
     In use, the microprocessor  500  executes instructions in the form of applications software stored in the memory  501  to allow communication with the user device  220 , for example to receive a service token and to provide payment options, and the merchant device  230 , for example to receive the registered initialization token and to provide provisioning data. The applications software may include one or more software modules, and may be executed in a suitable execution environment, such as an operating system environment, or the like. 
     Accordingly, it will be appreciated that the payment system  240  may be formed from any suitable processing system, such as any electronic processing device, including a microprocessor, microchip processor, logic gate configuration, firmware optionally associated with implementing logic such as an FPGA (Field Programmable Gate Array), or any other electronic device, system or arrangement. However, the payment system  240  may also be formed from a suitably programmed PC, Internet terminal, lap-top, or hand-held PC, a tablet, or smart phone, or the like. Thus, in one example, the payment system  240  is a standard processing system such as an Intel Architecture based processing system, which executes software applications stored on non-volatile (e.g., hard disk) storage, although this is not essential. 
     In other examples, such as described above, the payment system is formed of multiple computer systems interacting, for example, via a distributed network arrangement. As distributed networking is known in the art, it will not be described further in more detail. 
     In particular, the payment system may include or be in communication with a number of processing systems associated with each of an issuer, acquirer, card network and payment gateway, or alternatively, the payment system may be any one or more of these entities. 
     In one example as will be well understood in the art, the payment system sends the user account information and payment information to the merchant&#39;s acquirer. The acquirer then requests that the card network get an authorization from the user&#39;s issuing bank. The card network submits the transaction to the issuer for authorization and the issuing bank then authorizes the transaction if the account has sufficient funds to cover the amount payable. The issuer then routes payment to the acquirer who then deposits the payment into the merchant&#39;s account. 
     To illustrate further features of preferred practical implementations of the method, a further detailed example of a method for making payment to activate a mode of a service station will now be described with reference to  FIGS. 5A-5C . 
     At step  400 , a user connects or pairs their user device to an authentication device, for example through Bluetooth connectivity, Zigbee, Wi-Fi or any other suitable wireless communications protocol. Once a connection has been established, the authentication device provides a service token to the user device at step  405 . The service token is indicative of one or more pre-selected payment options associated with activating a mode of the service station, and/or also associated with a service session established between the user device and the service station. The user device then provides the service token to a payment system, such as a payment server at step  410 . The user device may provide the service token to the payment system in accordance with instructions provided by the user through a payment application executing on their device or other suitable interface. In one example, the service token could be sent from the user device via a text message to the payment server. 
     At step  415 , the payment system retrieves payment options (pre-selected by a merchant/owner/operator) from a data store using the service token which will typically be associated with a device identifier such as a unique device key. In this way, payment options applicable for a particular service station can be linked to the authentication device using the service token and device identifier. At step  420 , the payment system provides the payment options to the user device based on the service token. The available payment options are then displayed on a user interface of the user device including for example an interface provided by a payment application at step  425 . 
     At step  430 , the user selects a suitable payment option and provides payment information. This may be done through a digital wallet or alternatively the user may enter their bank account or card details as would typically occur in a standard e-commerce transaction with a merchant/owner/operator. The payment information is provided by the user device to the payment system at step  435 . 
     At step  440 , the payment system performs the payment and generates a payment token which will be indicative of the payment option selected by the user and be associated with the device identifier for the purposes of validation. The payment system may perform the payment in accordance with standard payment processing techniques involving an acquirer, card network, and issuer and optionally a payment gateway. 
     At step  445 , the payment token is provided to the user device via the communications network (e.g. mobile network, Internet etc.). At step  450 , the user device then provides the payment token to the authentication device in accordance with an instruction from the user to do so. The payment token may then be validated using at least one of, for example, the unique device identifier, decrypted using a unique key, verification of a digital signature generated from the payment system, and determination of whether the payment token is for the particular service station at step  455  to ensure that the correct device has received the payment token and that the payment option selected is valid for the particular service station. 
     At step  460 , the authentication device determines whether the payment token is valid. If it is found to not be valid then the process ends at step  465 . Otherwise, the process proceeds to step  470  where the authentication device determines a desired mode of the service station based on the payment made (for example, e.g. $1:00 to park a vehicle for 5 minutes, $2:00 to park a vehicle for 10 minutes etc.). Finally, at step  475  the authentication device is configured to control the service station in the desired mode in accordance with the payment option selected by the user. 
     Accordingly, it will be appreciated that in at least one example the above described methods and system may enable electrical appliances to be used on a ‘pay be use’ basis without requiring traditional forms of payment such as physical money (coins, notes) and bank cards. The ability to restrict usage of appliances in accordance with specific payment options (for example based on duration of use) may also make users more conscious of their energy usage which may lead to reduced energy consumption and more considered decision making around use of appliances. Furthermore, the ability to simply pay for use of appliances may additionally create a new revenue stream for accommodation providers who traditionally rent out rooms having several appliances available for use by their guests. 
     Whilst there have been described in the foregoing description preferred embodiments of the present invention, it will be understood by those skilled in the technology concerned that many variations or modifications in details of design or construction may be made without departing from the present invention.
