fig1 is a flow diagram for mobile transaction processing , according to an example embodiment . the components of the diagram are implemented in non - transitory computer - readable storage medium for execution on one or more processing devices that are configured to execute the components . the components are also enabled to operate and communicate with one another over a network . the network can be wired , wireless , or a combination of wired and wireless . it is noted that the components and the interactions of the components shown in the fig1 are presented for illustrative purposes in a sample scenario with a sample enterprise system . so , other arrangements and interactions of the components are possible without departing from the beneficial teachings presented herein and below . various embodiments herein provide a mechanism to enable a consumer to present their payment and / or loyalty information online . a web shopping site presents a two - dimensional ( 2d ) barcode to the consumer , who scans the barcode in with their mobile device , accomplishing the same end result as entering their credit card information . this also establishes a link between the consumer mobile device and the transaction — such that the mobile device can be used as the user interface ( ui ) to allow the customer to answer questions , redeem points , pay , or transact other secure business on their mobile device in a “ trusted ” environment . referring to the fig1 , a consumer visits a commercial website with the intention of making a purchase ; this can occur via a different device from a mobile device of the consumer or via the same mobile device . the consumer uses the traditional web shopping model to add items to their cart and proceeds to checkout . the business web application calls a mobile transaction web service with a transaction identifier ( id ), unique session id , or other information necessary to conduct the transaction . the transaction system returns barcode and string data containing the portal uniform resource locator ( url ) and the unique transaction id , digitally signed with the private key of the business . the web site displays the barcode or string , such that the consumer &# 39 ; s mobile device can acquire the string , via scanning it from the display or via an application that detects it on a page within the mobile device . the web site calls the web service and blocks ( waits on the transaction that is proceeding ), awaiting payment confirmation : or the web site registers for notification once payment has been completed . the consumer uses the retailer or mobile app to acquire the string via barcode or other technique . the business or mobile app connects to the web service via secure connection , either through existing over - the - air ( ota ) data connection , wifi , sms or other mechanism and presents the string . optionally , the consumer authenticates with the web service via their mobile device with a secret , such as a personal identification number ( pin ), secure element token , biometrics or other mechanism . the consumer is presented with a transaction summary and total amount , previously returned from the mobile transaction service . the consumer selects a payment method and confirms payment on the mobile device . payment is confirmed , and the mobile transaction service returns a payment confirmation authorization code and any other relevant information required to complete the transaction to the business web application . optionally , the mobile device may receive transaction updates , an electronic receipt or other information related to the transaction . fig2 is a diagram of a method 200 for mobile transaction processing , according to an example embodiment . the method 200 ( hereinafter “ transaction service ”) is implemented as instructions programmed and residing on a non - transitory computer - readable ( processor - readable ) storage medium and executed by one or more processors . the processors are specifically configured and programmed to process the transaction service . the transaction service operates over a network . the network is wired , wireless , or a combination of wired and wireless . the transaction service executes on one or more processors of a server . in some embodiments , the transaction service in a cloud processing environment and is available as a cloud service over the internet to enterprises and consumers . in other cases , the transaction service is controlled from a server of a specific enterprise offering mobile transaction processing . so , the transaction service can be a third - party service offered to a plurality of enterprises or can be controlled and managed within a processing environment of a specific enterprise offering a specific mobile transaction processing . both embodiments can occur simultaneously in the industry as well utilizing different instantiations of the transaction service . that is , for security reasons financial institutions may desire to manage their own version of the transaction service within their own controlled processing environment , where as retail establishments may opt for third - party outsourcing to utilize the transaction service . the processing of the transaction service interacts with consumer mobile device apps , applications and services of enterprise systems , and / or other third - party services utilized by consumers and / or enterprises for transaction processing , loyalty processing , and / or other customer relationship management processing . at 210 , the transaction service receives a request to complete a transaction . the transaction occurring between a consumer and an enterprise terminal device ( e . g ., website , kiosk , and the like ). receipt of the request can occur in a variety of manners . for example , at 211 , the transaction service acquires the request from the enterprise terminal device ( or application processing thereon ), where the enterprise terminal device is a website portal for an enterprise and the transaction is the completion of a shopping session with a consumer on that website and the shopping cart of the consumer includes one or more goods or services purchased from the enterprise . in another case , at 212 , the transaction service receives the request as an url link to a specific session that is occurring between the consumer and the enterpriser terminal device . continuing with the embodiment of 212 and at 213 , the transaction service acquires the url link from the mobile device of the consumer via interactions of the consumer . in other words , the consumer sends the url via a mobile device to the transaction service and provides with the url the specific session that the consumer is engaged in with the enterprise terminal device . at 220 , the transaction service provides a unique token back to the enterprise terminal device for uniquely identifying the transaction . this token can include a variety of information ( discussed above with reference to the fig1 ). the token permits the session for the transaction to be identified , the transaction to be identified , the consumer to be identified , and the enterprise or enterprise terminal device to be identified . in an embodiment , the token is a barcode or a quick response ( qr ) code . in an embodiment , at 221 , the transaction service generates the unique token to identify the token , the consumer , the enterprise for the transaction , and a communication session occurring between the consumer and the enterprise terminal device . at 230 , the transaction service acquires from the mobile device the token . the token is now signed by the mobile device . according to an embodiment , at 231 , the transaction service obtains the signed token via a mobile app of the mobile device that scans and signs the token from a display of a different device from that which is associated with the mobile device . in another case , at 232 , the transaction service obtains the signed token via a mobile app of the mobile device that detects the transaction occurring on a web browser of the mobile device and detects the presence of the token once interested for completing the transaction . at 240 , the transaction service validates the signed token returned from the mobile device . in an embodiment , at 241 , the transaction service associates the token with the consumer and a preregistered account of the consumer having the payment details . at 250 , the transaction service causes the transaction to complete using the payment details associated with the consumer . in this way , the consumer does not have to enter he payment details to complete a transaction . according to an embodiment , at 251 , the transaction service processes the payment details for the transaction on behalf of the enterprise terminal device and notifying the enterprise terminal device of the same . in another situation , at 252 , the transaction service sends the payment details to the enterprise terminal device for completing the transaction on behalf of the consumer . fig3 is a diagram of another method 300 for mobile transaction processing , according to an example embodiment . the method 300 ( hereinafter “ mobile app ”) is implemented as instruction and programmed within a non - transitory computer - readable ( processor - readable ) storage medium that executes on one or more processors of a mobile device ( e . g ., mobile phone , personal digital assistant ( pda ), tablet , laptop , etc . ); the processors of the mobile device are specifically configured to execute the mobile app . the mobile app is operational over a network ; the network is wired , wireless , or a combination of wired and wireless . the mobile app is controlled by a consumer ( customer and / or user ) and interacts with the transaction service , represented by the method 200 of the fig2 and also interacts with an enterprise terminal device ( discussed below with reference to the fig4 ). it is noted that the mobile app can be installed and initiated by the consumer on the mobile device in a variety of manners before the processing occurs as detailed below . for instance , in one situation during a registration process of the mobile device with a transaction service ( such as the one discussed above with reference to the fig2 ), the mobile app is downloaded and initiated on the mobile device , hi another instance , during an initial contact by the mobile device with an enterprise terminal device of an enterprise , the customer is directed to a website of the enrollment service ( discussed above with reference to the fig2 ) where the registration process occurs and the mobile app is downloaded and initiated on the mobile device . other situations can result in the mobile app &# 39 ; s installation as well . for instance , as part of a registration process in a loyalty program with a specific enterprise , the consumer may agree to engage the transaction service features . this may result in the enterprise &# 39 ; s registration service in contacting the transaction service with details expected by the transaction service ( as discussed above ) on behalf of the consumer , and at some later point result in the transaction service dynamically pushing the mobile app for initiating on the mobile device of the consumer . at 310 , the mobile app detects a token for user in a transaction . the transaction occurring between a consumer of a mobile device and an enterprise , via an enterprise transaction device . in an embodiment , at 311 , the mobile app identifies the token from a display of another device that is different from the mobile device and the token is scanned into the mobile device via a camera of the mobile device . the token displayed on a complete transaction screen for the enterprise terminal device . in another situation , at 312 , the mobile app identifies the token as being embedded as an image in a website page of the enterprise terminal device that the browser of the mobile device is accessing . at 331 , the mobile app sends the signed token to a transaction server ( such as the transaction service represented by the fig2 above ). the transaction service is separate and apart from the enterprise terminal device . in another case , at 332 , the mobile app sends the signed token to an application of the enterprise terminal device . at 340 , the mobile app receives an indication that the transaction was paid for by the consumer and that the transaction completed with the enterprise terminal device . according to an embodiment , at 350 , the mobile app receives transaction details , loyalty information , and / or an electronic receipt for the transaction once it completes . fig4 is a diagram of yet another method 400 for mobile transaction processing , according to an example embodiment . the method 300 ( hereinafter “ enterprise terminal app ”) is implemented as executable instructions and programmed within a non - transitory computer - readable ( processor - readable ) storage medium that executes on one or more processors of an enterprise terminal ( e . g ., cashier - manned device , self - service kiosk , digital sign , website of a retail , etc . ); the processors of the enterprise terminal app are specifically configured to execute the enterprise terminal app . the enterprise terminal app is operational over a network ; the network is wired , wireless , or a combination of wired and wireless . the fig1 described the processing for automating transaction processing of a consumer and / or a consumer &# 39 ; s mobile device as a whole . the fig2 described the processing from the perspective of the remote and server / cloud based transaction service ; the fig3 described the processing from the perspective of the consumer &# 39 ; s mobile app on a consumer &# 39 ; s mobile device ; and the enterprise terminal app of the fig4 describes the processing from an enterprise &# 39 ; s transaction system processing on a retail terminal device . a consumer transaction for a retail terminal device is automated via the interaction among the transaction service ( of the fig2 ), the mobile app ( of the fig3 ), and the enterprise terminal app ( of the fig4 ). at 410 , the enterprise terminal app interacts with a consumer to complete a transaction . according to an embodiment , at 411 , the enterprise terminal app interacts with the consumer via one or more website pages of a web portal for an enterprise . the web portal or site being viewed as an enterprise terminal device . at 420 , the enterprise terminal app , identifies a point for the transaction where payment is required from the consumer . at 430 , the enterprise terminal app requests that a transaction server intervene in the transaction and complete payment for the consumer . this can occur out - of - band with the consumer , such as via transactions occurring via a mobile device of the consumer as presented above with respect to the fig1 - 3 . in an embodiment , at 431 , the enterprise terminal app presents a token generated by the transaction service in an interface screen presented to the consumer for completing the transaction . the mobile device processes the token to complete the transaction . at 440 , the enterprise terminal app receives an indication that payment from the consumer was received and the transaction is completed . the payment details processed by or acquired from the transaction server . the above description is illustrative , and not restrictive . many other embodiments will be apparent to those of skill in the art upon reviewing the above description . the scope of embodiments should therefore be determined with reference to the appended claims , along with the full scope of equivalents to which such claims are entitled . the abstract is provided to comply with 37 c . f . r . § 1 . 72 ( b ) and will allow the reader to quickly ascertain the nature and gist of the technical disclosure . it is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims . in the foregoing description of the embodiments , various features are grouped together in a single embodiment for the purpose of streamlining the disclosure . this method of disclosure is not to be interpreted as reflecting that the claimed embodiments have more features than are expressly recited in each claim . rather , as the following claims reflect , inventive subject matter lies in less than all features of a single disclosed embodiment . thus the following claims are hereby incorporated into the description of the embodiments , with each claim standing on its own as a separate exemplary embodiment .
