Abstract
A method and system for purchasing credit for a prepay meter comprises a meter, a transaction unit, an information key or token and a remote transaction server. In normal operation the key is inserted into meter and information is exchanged with the meter such as the amount of prepay credit available. To purchase additional credit the token is inserted into a transaction unit, the transaction unit being in communication with a remote transaction server storing details of the customer's bank account or credit card. The token is then updated with information reflecting the amount of supply purchased. On reinsertion into the meter, the updated information relating to the payment is transferred to the meter. The transaction may also be used for part payments or settlement of a bill. The transaction unit may be located in the user's home or at a central point accessible by a large number of users. In a further embodiment the transaction unit may be incorporated into the meter. The key may also carry additional information written to the key by the meter or by the transaction unit. This may include usage information, new software or tariff information. The key maybe used for one of several meters which use the same transaction unit.
Description
<p>METHOD AND SYSTEM FOR PURCHASING ENERGY AND CORRESPONDING</p>
<p>TRANSACTION UNIT</p>
<p>The present invention relates to the way a consumer can purchase and use energy (water, gas, heat or electricity) delivered by a utility.</p>
<p>CurrentLy, consumers for domestic energy can be cLassified in two categories, nameLy on the one hand, what we could call the "prepayment" customers, and, on the other hand, the "non prepayment" customers.</p>
<p>For "prepayment" customers, a specific meter with a built-in key or token interface is installed at the consumer's dwelling. The meter works once a corresponding prepaid key or token (for instance a prepaid card) has been inserted into the interface and energy is delivered until the amount for which the user has paid for is reached. Then, the user has to go back to the shop or other retail premise in order either to buy a new key, or to recharge his key. Today, the applicant selLs such a specific meter either for gas delivery or for electricity delivery. This solution has however several drawbacks for both the consumer and the utility: The user must leave his house to visit the shop. This is inconvenient to the user, especially in case this shop is far away from the user's house or has limited opening hours. The utility must contract with a third party to provide the vending infrastructure. This is expensive. Both third parties (infrastructure provider and shopkeeper) will take a percentage of the transaction value. The money needs to be transferred first to the infrastructure provider rather than directly to the utility.</p>
<p>For "non prepayment" customers, traditional billing methods are used.</p>
<p>Namely the meter is read periodically by a meter reader or the customer. The meter readings are Loaded into the utilities billing system, and a bilL is generated.</p>
<p>Payment is then made when the bill is received, or via a direct debit arrangement. Here again, the non prepayment solution has several drawbacks: The solution of reading and transferring data manually is slow, prone to human error and expensive. In addition, some premises can not be accessed at any time and there is no way to verify data accuracy. Without accurate meter data, erroneous bills can be generated. This leads to additional cost. In addition such customers do not always reliably pay their bills leading to additional costs and cash flow issues.</p>
<p>Even with accurate reads there is a large time lag between consumption of the energy and paying for it. This is bad for the utility's cash flow, and does not allow the customer to manage his usage of energy as efficiently.</p>
<p>Consequently, none of the existing solutions is completely satisfactory, neither for the customer' side, nor for the utility's side.</p>
<p>A first aim of the present invention is to provide a unique solution which enables simplification of the process of purchasing energy for customers, while being satisfactory for each involved party (namely the customer and the utility).</p>
<p>To this aim, a first aspect of the invention is a system for purchasing energy from a utility, comprising at least a meter at a consumer's dwelLing, said meter being adapted to measure and store amounts of energy delivered to said consumer, and a key or token adapted to store information relating to the purchase of an amount of energy, wherein said meter comprises a key or token read/write interface for exchanging data with said key or token and is adapted to control energy delivery according to information read from said key or token, characterized in that said system further comprises -a transaction unit comprising its own key or token read/write interface for exchanging data with said key or token; and -a remote transaction server storing data relating to said consumer's bank account and/or credit card, wherein said transaction unit is adapted to establish a data communication with said transaction server through a data communication link in order to perform a transaction relating to said purchase, and is adapted to update at least part of the information stored on said key or token as a result of said transaction.</p>
<p>Consequently, a direct transaction can be performed in a very simple way.</p>
<p>The transaction may consist of the payment of a monetary value corresponding to a pre purchase of energy. Consequently, said transaction unit is adapted to write updated information in relation to said payment, and said meter is adapted to authorize energy delivery to the limit of said prepaid monetary value. At the time of the transaction, the consumer may have the possibility to determine the amount of energy he wants to purchase in advance. In this case, said transaction unit is advantageously adapted to write updated information corresponding to said amount of energy, and said meter is adapted to authorize energy delivery until a measured amount of delivered energy is equal to said amount of energy. Alternatively or in combination, the consumer may choose to prepay without knowing in advance the corresponding amount of energy. In this case, said transaction unit is advantageously adapted to write updated information corresponding to said prepaid monetary value, and said meter is adapted to equate said prepaid monetary value into a corresponding amount of energy, and to authorize energy delivery until a measured amount of delivered energy is equal to said corresponding amount of energy.</p>
<p>Transaction may also correspond to post-payment, either totaL or part payment corresponding to an amount of energy which has already been delivered to the consumer. Consequently said meter is alternatively or further adapted to write on said key or token information relating to an amount of energy already delivered to said consumer, and said transaction unit and transaction server are adapted to perform a transaction corresponding to payment, or part payment, or at least billing for a post purchasing of said amount of energy already delivered to said consumer from information stored on the key or token; at the end of the transaction, said transaction unit writes updated information on said key or token as a result of said transaction.</p>
<p>Advantageously, said meter may be adapted to authorize energy delivery depending on said updated information.</p>
<p>Transaction may also result from an agreement between the utility and the consumer that energy will be delivered provided payment has been received within a previously agreed prior timescale (e.g. monthly, quarterly, ...) Consequently, the system according to the invention enables a flexible use for a consumer since it may combine prepayment, post payment and even time based payment.</p>
<p>Said transaction unit may be located at the consumer's dwelling for usage limited to said consumer.</p>
<p>Alternatively, said transaction unit may be located at a free access Location, for usage extended to a group of consumers.</p>
<p>During a transaction, the transaction server may also send to said transaction unit additional information. Said additional information may consist of energy usage profile determined by said transaction server from data read from said key or token by said transaction unit and previously written in said key or token by said meter. AlternativeLy, said additional information may consist of a new tariff. In this case, said transaction unit writes said new tariff on said key or token for further usage by said meter.</p>
<p>In one possible embodiment of the invention, said transaction unit is integrated within the meter. In this case, a single read/write interface can be used for exchanging data with the key or token.</p>
<p>Key or token is preferably associated with a specific and unique identification number linked to the consumer which is also sent by said transaction unit to said transaction server through said data communication link. In this case, transaction can be performed only if said transaction server has first recognized said consumer from said identification number.</p>
<p>A second aspect of the invention is a transaction unit for energy purchase, characterized in that it comprises: -a key or token read/write interface for exchanging data with at least a key or token adapted to store information relating to the purchase of an amount of energy; -means for establishing a data communication through a data communication link with a remote transaction server storing data relating to said consumer's bank account and/or credit card, in order to perform a transaction relating to said purchase, and -means for updating at least part of the information stored on said key or token as a resuLt of said transaction.</p>
<p>Said transaction unit may advantageously further comprise displaying means, and/or a man machine interface enabling a consumer to enter data.</p>
<p>A third aspect of the invention is a method for purchasing energy from a utility within a system comprising at least a meter at a consumer's dwelling and a key or token adapted to store information relating to the purchase of an amount of energy, said meter comprising a key or token read/write interface for exchanging data with said key or token, said method comprising the steps of measuring and storing at the meter amounts of energy delivered to said consumer, and of controlling energy delivery according to information read from said key or token, characterized in that said method further comprises the foLlowing steps: -inserting said key or token into a key or token read/write interface of a transaction unit; -establishing, at said transaction unit, a data communication through a data communication link with a remote transaction server storing data relating to said consumer's bank account and/or credit card, in order to perform a transaction relating to said purchase, and -updating, at said transaction unit, at least part of the information stored on said key or token as a result of said transaction.</p>
<p>Another problem lies in the fact that most existing systems for purchasing energy work only with electricity meters, since they require the presence of a mains power supply which cannot be used for gas or water meter mainly for safety reasons. Typical solutions for gas and electricity use a low power transmitter in the gas meter to send data to the electricity meter or to another unit.</p>
<p>Consequently, a need exists to provide a common solution for the purchase of energy and the transfer of energy data whatever the energy type (typically eLectricity, gas, heat and water).</p>
<p>To this aim, in a specific embodiment of a system according to the invention, the system comprises, for a same consumer, one or several meters for measuring different types of energies chosen among electricity, water, heat and gas. In this case, information stored in said key or token and relating to the purchase of a given amount of energy include the energy's type. Consequently, with the same transaction unit and a single key or token, the user can purchase one or several types of energies from the same utility.</p>
<p>Alternatively, separate keys or tokens adapted for use with several different meters can be delivered to a same consumer who can use the same transaction unit.</p>
<p>Features and advantages of the invention will become apparent from the following description of the invention given by way of non-limiting examples only and with reference to the accompanying drawings, in which: -Figure 1 shows schematically the working of a system according to a preferred embodiment the present invention; -Figure 2 shows schematically the front face of a transaction unit, visible from the consumer; -Figure 3 is a schematic functional diagram of a transaction unit according to the invention.</p>
<p>In reference with figure 1, the concept of the invention is to have an ultra low cost vending point or transaction unit 1, preferably located at the consumer's dwelling 2, said unit 1 being adapted to connect to a remote transaction server 3 via a standard communication link 4, for instance the existing telephone line. The consumer has also a key or token 5, and this key is used in combination with transaction unit 1 either to charge one or several electricity, gas or water meters 6a, 6b (transaction corresponding to a prepayment), and/or to enable a customer to send data corresponding to energy aLready consumed for billing or payment purpose (transaction corresponding to post payment).</p>
<p>In case of figure 1, it has been assumed that consumer has chosen to pay immediately each transaction made through transaction unit 1 and transaction server 3 by credit transfer from his bank 7 to utility bank 8. In case transaction server belongs to the utility, there is no other party participating to the transaction than consumer (via his bank 7) and utility (via its own bank 8). As it can be seen from figure 1, in case transaction server 3 does not belong to the utility, transaction server 3 has to communicate also with a separate Customer Relationship Management and bilLing system 9 of the utiLity, in order to notify the utility's own computer systems when a transaction takes place.</p>
<p>In order to provide a secure and reliable means of transferring data, key or token 5 is preferably associated with a specific and unique identification number of the PIN code type linked to the consumer.</p>
<p>Figures 2 and 3 schematically show a preferred embodiment for transaction unit 1. More precisely, figure 2 shows a possible front face of said unit 1, while figure 3 explains the interaction of different components of the unit from a functional point of view. Transaction unit 10 must have first a key or token read/write interface 10 for accepting corresponding key 5 and exchanging data with said key. A keypad 11, or any other type of man machine interface means suitable for enabling the user to enter alphanumeric data, is also provided. Display means 12 will enable to establish a dialog with the user. Of course, other solutions may be adopted (for instance microphone and Loudspeaker), but generally at higher cost. OptionalLy, transaction unit 1 may also include indicator Lights, for instance a red Led 13, and a green led 14, in order to give to the user an indication concerning the transaction's progress. Alternatively, this indication could also been made through specific messages displayed by display means 12. In order to be able to establish a data communication with transaction server 3, transaction unit 1 is also provided with a modem 15 (see figure 3). Transaction unit has also a power supply unit 16 which may supply power to all components either from the main electrical network or from a battery, or both. Inter working of the different components is controlled by a micro controller 17 and corresponding suitable software means (not shown).</p>
<p>A structured walk through of the system operation is explained below: Contract Initiation: In the preferred embodiment, the following steps wilt be sequentially performed: i. Consumer signs a specific contract with utility for one or several energies among electricity, gas and water.</p>
