FIELD OF THE INVENTION
The present invention relates to an apparatus and a method for commercial transactions using a communication device. More particularly, but not exclusively, the present invention relates to an apparatus and a method of transactions via a wireless or a landline communications device using a transaction card.
BACKGROUND OF THE INVENTION
Electronic fund transfer over mobile phones is growing popular. Many systems include combining a point of sale (POS) device with a wireless communication device such as a cell phone.
These POS devices include a processor as well as an input device to receive and process information from a transaction card such as a debit card, a credit card, a cash card, a stored value card, an ATM card or combinations thereof and the like. The input device may include a bar code reader, a magnetic stripe reader, an integrated circuit reader, a smartcard reader, a fingerprint scanner, an optical scanner, a signature pad, an alphanumeric keypad (including a PIN pad), a proximity detector, an audio recording device, a camera or combinations thereof and the like. The processor of the POS device receives information from the transaction card and sends it to a remote computer via a communication network. This information can be transmitted by the processor via the wireless communication device. The wireless communication device includes a transceiver, a communication port or any other type of similar communication device capable of transmitting information received by the portable transaction device processor from the transaction card to the remote computer. The communication link between the remote computer and the wireless communication device can be provided by the processor of the wireless communication device. The portable transaction device can also include a Global Positioning System (GPS) locator chipset so the location of the POS can be tracked by the remote computer. The remote computer sends the information it has received to the processor of the institution that has issued the transaction card that is being used. The processor of this institution validates the requested transaction and sends this information to the processor of the portable transaction device via the remote computer and the wireless communication device which are linked to each other by way of the aforementioned communication network.
Known systems which combine POS devices with wireless communication devices present certain drawbacks such as the inconvenient length of time to receive information regarding whether or not a given transaction has been accepted or refused. Other systems currently available include PayPal mobile, Obopay, Swipepay mobile. These solutions use either SMS or FPRS as the means of communication. However, these communication methods often suffer from an unbounded delay or become unavailable in locations where these services are not provided. Another drawback of existing systems is that they require registration and installation of software which are usually inconvenient for users to install. More importantly, these systems do not work for all mobile phones given the many different combinations of hardware and software platforms. Moreover, these solutions are not secure. They are prone to spyware or keylogger. Hence they are not compliant with payment card industry standards such as PC1 PED.

FIG. 1 shows a transaction network 10 including a transaction apparatus 12 and communication device 14 which together form a transaction and communication assembly 16. The transaction apparatus 12 captures transaction data and, in some implementations, provides a user with feedback. Also shown is a transaction server 18 and a transaction processor/issuer 20 which together form a remote processor assembly 22. A request for a transaction occurs at the transaction apparatus 12 via a transaction card 24 (see FIG. 4). The transaction apparatus 12 captures information from the transaction card and converts this information into an audio signal. The audio signal is transmitted to the communication device 14 for transmission to the transaction server 18 via a communication network 26 (e.g. Internet, GSM/GPRS network). At the transaction server 18, the audio signal is converted into a digital signal and transmitted to the remoter processor/issuer 20 via a communication or payment network 28 (e.g. Internet, VisaNet, BankNet). The remoter processor/issuer 20 validates this request by accepting or denying the request and sends this validation information to the transaction server 18 which then converts this digital signal into an audio signal and transmits it back to the assembly 16 providing the seller and buyer with a confirmation or a rejection message. As such, the communication device 12 acts as a receiver of the transaction data in analog audio format and also as a conduit to transmit the transaction data to a transaction server 18 via the communication network 26.
With reference to FIGS. 2, 3 and 4, an example of a transaction and communication assembly 16 is shown including a portable transaction apparatus 12 in the form of a point of sale (POS) device linked to a communication device in the form of mobile phone 20 via a communication link in the form of a cable 30. The cable 30 includes a pair of opposite connector ends 32 for being mounted to the phone jack 33 (see FIG. 3) of the POS device 12 and the jack 34 of the mobile phone 20.
The POS device 12 includes an output device such as a user interface in the form of a display screen 36 which can be an LCD screen for example. The display screen 36 displays transaction information and instructions as well as providing other feedback to the user. The POS device 12 also includes an input device 38 such as card reader slot 39 for swiping or inserting the transaction card 24 and capturing information therefrom. The POS device 12 can also include an additional input device 40 in the form of a control pad including a PIN pad 42, and other control buttons 44 allowing the user to enter transaction information which is also captured by the POS device 12 and converted into an audio signal for transmission to the communication device 14.
The transaction card 24 includes a magnetic stripe 46 as well as an IC chip 48.
With reference to FIG. 5, the transaction device 12 includes a controller 50 in the form of a microcontroller unit (MCU). The input device 38 can be in the form of an analog signal reader 52 such as a magnetic stripe reader and/or a digital signal reader 54 such as an Integrated Circuit (IC) or Smart Card or EMV reader. In an embodiment, the transaction apparatus 12 is powered by a power source 56 optionally includes a printer 58 such as a thermal printer for example. As mentioned above, in an embodiment, the input system of the transaction apparatus 12 includes the input device 38 as well as an additional input device in the form of a control pad 40.
With reference to FIGS. 1 to 5, the general operation of the invention will now be described in accordance with a non-limiting illustrative embodiment thereof.
In order to execute a commercial transaction, the user swipes the card 24 through the slot 39; the analog information on the magnetic stripe 46 is captured by the magnetic stripe reader 52 and transferred to the MCU 50. In another embodiment, the digital information from the IC chip 48 is captured by the digital signal reader 54 and is transferred to the MCU 50. Optionally, a PIN number may also be required to be entered via the PIN pad 42 and the data is encrypted by the MCU 50.
The transaction data whether originally received in analog format or in encrypted digital format is converted by the MCU 50 into an analog audio signal suitable for transmission over the analog communication link between the transaction device and the communication device. In this example, this audio signal is then transmitted to the mobile phone via cable 30.
Transaction data is then transmitted to the transaction server 18 for processing. The transaction server 18 decrypts the signal and converts it into a digital signal. This data is then transmitted to the processor/issuer 20 for validation. The processor/issuer 20 receives the transaction data and then validates the information in order to accept or reject the requested transaction. Once the transaction has been accepted or rejected, the processor/issuer 20 produces a message confirming the foregoing and transmits this information back to the transaction server 18 in digital format.
The transaction server 18, having received the message from the processor/issuer 20, converts it into an audio signal and transmits this information via the communication network 26 back to the mobile phone 14.
The mobile phone 14 transmits the message back to the portable transaction device 18 via cable 30. The MCU 50 decodes the analog audio signal and converts it back into appropriate data format for processing and display via screen 36.
In another embodiment, the binary digital signal, whether originally received in analog format or in encrypted digital format is compressed by the MCU 50 and converted into a hexadecimal signal. This hexadecimal signal is then further compressed by the MCU 50 and converted into a dual-tone multi-frequency (DTMF) audio signal. This DTMF signal is then transferred by the MCU 50 to the mobile phone 14 and transmitted to the transaction server 18.
The transaction server 18 decompresses the DTMF signal and converts into a hexadecimal signal. This hexadecimal signal is then further decompressed by the transaction server 18 and converted into a binary digital signal. The transaction server 18 then transmits this binary digital signal to the remote processor/issuer 20. The remote processor/issuer 20 receives the binary digital signal and then validates the information in order to accept or reject the requested transaction. Once the transaction has been accepted or rejected, the processor/issuer 20 produces a binary digital signal confirming the foregoing and transmits this information to the transaction server 18. The binary digital signal is compressed into a hexadecimal signal and then recompressed into a DTMF audio signal which is then transmitted to the mobile phone 14. The mobile phone 14 then transmits this DTMF audio signal to the MCU 50 which decompresses the DTMF audio signal and converts it into a hexadecimal signal. Finally this hexadecimal signal is then further decompressed and converted into an appropriate data format to be displayed via screen 36.
Therefore, in an embodiment, there is provided a payment system consisting of a transaction apparatus 12 and a transaction server 18. The transaction apparatus 12 allows for card data and PIN capture via the input device 38 and the control pad 40. The controller 50 controls the operation flow of the transaction apparatus; it provides the encryption required for transaction and other channel encryptions as well as memory. Audio communication between the transaction apparatus 12 and the transaction server 18 is provided by the communication device 14. Operation of the transaction apparatus is displayed on the user interface (the display screen) 36. The transaction server 18 is used to decrypt the data sent by the communication device 14 where the data is translated and forwarded to the payment network 28 including a processor/issuer 20 for further processing.
For example, in transactions such as in taxi or limousine services, the driver swipes the credit card 24 of the passenger in the magnetic stripe reader 52 of the POS device 12 which converts this analog data into an audio signal and is connected to the driver's mobile phone 14 via the hands-free jack 34 for transmitting this data. The mobile phone 14 sends the audio signal to the remote transaction server computer 18 via the communication network 26 between the transaction server computer 18 and the mobile phone 14. The transaction server computer 18 communicates with the remote processor/issuer 20 of the financial institution that issued the passenger's credit card 24 and validates the requested transaction by accepting or refusing it. The foregoing information is then sent back to the transaction server computer 18 which converts it to an audio signal that is sent to the POS device 12 via the mobile phone 14. The display screen 36 informs the driver and the passenger if the transaction was accepted or not.
In another example, the apparatus, system and method provide for online purchasing or money transferring. Hence, the transaction apparatus 12 is used for online purchase or money transfer.
FIG. 6 shows a transaction network 11 similar to the transaction network 10 but including a merchant server 60 in communication via a communication network 62 with the transaction serve 18 and with a merchant interface 66 provided by a remote device such as a computer via a communication network 66 (e.g. the internet).
Therefore, there is provided an online system for commercial transactions using a transaction card 24 via a communication device 14. The system is exemplified by the transaction network 11 and includes a transaction apparatus 12 linked to the communication device 14, a merchant server 60 providing a remote interface 66 to be accessed by the user and a transaction server 18 linked to both the communication device 14 and the merchant server 60. The merchant 66 interface allows for requesting a transaction. The merchant server 60 sends this request to the transaction server 18 which converts this information into an audio signal and sends this audio signal to the communication device 14 since it is linked therewith for the transmission of audio signals therebetween. The audio signal from the communication device 14 is sent to the transaction apparatus 12 which converts it to an appropriate format so as to be displayed through the display screen 36. The user then follows the displayed instructions and makes a payment as previously described.
In one example, the user accesses the merchant interface 66 such as a website to purchase. During checkout, the user selects the present method as payment and enters their mobile phone number in the merchant website 66. The merchant website 66 sends the user phone number along with the purchase details to the transaction server 18 via the merchant server 60 and communication networks 66 and 662. The transaction server 18 receives the request from the merchant and calls the phone number provided by the user. The mobile phone 14 picks up the call, the transaction information including the payment amount, merchant name and the like is sent from the transaction server 18 to the mobile phone 14 in audio form such as through a global system for mobile (GSM) network 26 in DTMF waveform for example. The user connects the transaction apparatus 12 to their mobile phone 14 and proceeds with the payment instructions displayed on the display screen 36. The user may have also connected their mobile phone 14 to the transaction apparatus 12 prior to entering their phone number in the merchant website 64. The transaction apparatus 12 receives the audio signal through the hands-free output interface or jack 34. The controller 50 inside the transaction apparatus 12 decodes the transaction information and the transaction data are displayed to the user on the screen 36. Following the instructions on the screen 36, the user swipes their transaction card 24 in the slot 39 of the magnetic card reader 50.
The data is then sent to the mobile phone 14 in analog audio form. Thus, the mobile phone 14 receives the analog audio data as a normal audio input. The mobile phone 14 then encodes the audio input using for example the normal GSM voice codec and sends this audio to the calling transaction server 18. The transaction server 18 receives the data in analog audio form, decodes the data to recover the transaction card data and the payment details. The transaction data is reformatted and sent to the remote processor/issuer 20 which either approves or rejects the transaction. The transaction result is sent back to the transaction server 18. The transaction server 18 transforms the transaction data to an audio signal such as DTMF waveform and sends it to the mobile phone 14 and in turn to the transaction apparatus 12. The transaction apparatus 12 decodes the data and displays the transaction result on to the screen 36 to inform the user. A receipt is sent to the email of the user as a record and the online purchase is completed. In the above embodiment, it should be noted that the mobile phone 14 does not require installation of any software and it acts only as a conduit of analog audio for data communication between the transaction a and the transaction server.
With reference to FIGS. 7 and 8, there is shown another embodiment of the transaction and communication assembly, denoted here as 16′.
The assembly 16′ includes a communication device 14 (a mobile phone) linked via a cable 30 to a transaction apparatus 12′. The transaction apparatus 12′ comprises one-way device without a screen or control pad and as such, only includes an input device 38′ in the form of a slot 39′ for capturing information from a transaction card 24 and sending this information without conversion directly to the mobile phone 14 via cable 30. The output device of the assembly 16′ is provided by the mobile phone 14 in the form of its display screen 36′. The additional input device of the assembly 16′ is also provided by the mobile phone 14 in the form of a control pad 40′ or keypad. Furthermore, the controller 51 of the mobile phone 14 is the controller of the assembly 16′. As such, in this embodiment, installation of a software application controller 51 is necessary. This software application is used to convert between audio and digital signal and to receive and transmit and audio data to and from the hands-free interface 41.
For example, to send money, the sender plugs the transaction apparatus 12′ into the mobile phone 14 and selects via the keypad 40′ a “send money” function on the software application displayed via screen 36′. The user enters the recipient phone number or email address and transaction amount. Following instructions on the mobile phone application via screen 36′, the user swipes the transaction card 24 against the card reader slot 39′ on the transaction apparatus 12′. The analog signal from the magnetic card 24 is sent via the hands-free interface 41 where the software application of the controller 51 converts the received signal back to binary data for example as stored on the magnetic card 34. Optionally, the user has to enter their PIN for authentication as in the case of a debit card transaction through the software application.
As explained above with respect to the transaction network 10 of FIG. 1, after the user has confirmed the transaction, a call is made to the transaction server 18. The transaction card data, along with the transaction data, are encoded and sent to the transaction server 18 in the form of general-packet radio-service (GPRS) data. The transaction server 18 decodes the transaction data, reformats and sends this data to the processor/issuer 20 for approval. This validation information data is then returned to the transaction server 18. The validation data is sent back from the transaction server 18 to the mobile phone 14 in audio format and converted by the software application in the controller 51 for displayed to the user via screen 36. For recording purpose, a receipt is sent as an email and/or SMS to the sender. Another message is sent to the recipient either as an email or SMS to inform the recipient of the transaction and provides the recipient with the transaction number and authentication number for accessing the transaction.
In another example, in order to receive money, the recipient plugs the transaction apparatus 12′ into the mobile phone 14 and selects the “receive money” function on the software application. The user enters the transaction number and authentication number. Following instructions on the mobile phone 14 application, the user swipes the card 24 against slot 39′ of transaction apparatus 12′. The analog signal from the magnetic card is sent via the hands free interface 41 where the software application of the controller 51 converts the received signal back to binary data as stored on the magnetic card. Optionally, the user has to enter his PIN for authentication as in the case of a debit card transaction through the software application.
After the user has confirmed the transaction, a call is made to the transaction server 18. The transaction card data, along with the transaction data, are encoded and sent to the transaction server 18 as GPRS data. The transaction server 18 decodes the transaction data, reformats and sends them to the processor/issuer for approval. The transaction result is then sent back from the transaction server 18 to the mobile phone 14 where the data is displayed to the user. For recording purpose, a receipt is sent as an email and/or SMS to the sender. Another message is sent to the recipient either as an email or SMS to inform the recipient of the transaction result.
It is to be understood that the invention is not limited in its application to the details of construction and parts illustrated in the accompanying drawings and described hereinabove. The invention is capable of other embodiments and of being practiced in various ways. It is also to be understood that the phraseology or terminology used herein is for the purpose of description and not limitation. Hence, although the present invention has been described hereinabove by way of embodiments thereof, it can be modified, without departing from the spirit, scope and nature of the subject invention.
