Simultaneous offline and online validation of tickets and capacity with the bikubo app

The bikubo app can be installed on iOS and Android devices. The download links for both repositories are:

• iOS
• Android

Simultaneous online and offline validation means that the checks to be performed regarding QR / barcode readings and/or localizadores are looked up in the bikubo server databases, and also in the device's internal database. The considerations to take into account with this system are:

• This validation system is useful for cases where there is coverage at the site, but it is not very secure or is intermittent, and the connection to the server may be lost at some point, in which case you have the backup of offline validation.
• If the result of the validation on the server differs from the validation against the internal database, the app displays the result of the server validation.
• The validation process is somewhat slower, having to perform queries and changes in two databases, server and internal.
• It offers the advantage of having the backup of checking in the internal database, in case of connection failure with the server.
• In case of loss of connection with the server, and only offline validation is performed, this system automatically sends the information of the tickets validated as soon as it recovers the connection with the server, so that the tickets validated offline by the validator are also validated on the server and thus other validators have the updated validation information.

If you choose this validation system, it is not possible to display the capacity data, the user must select validate against server or against internal db, to know the capacity according to one or the other database.

Prior to validation, it is required to download the tickets from a place with connection, so that they are in the internal database of the device.

The steps to perform validation at the door are as follows:

• Open the app on the device.
• Log in with the username and password. This data is displayed in the bikubo intranet, on the 'My data' screen.
• If you have previously downloaded tickets on that device, click on 'Clean Database'.
• With an internet connection, click on 'Download tickets'.
• Select 'Validate against internal DB and Server' on the main screen.
• To scan a QR/barcode, click on 'Open scanner', and the camera is activated to proceed to focus it towards the QR/barcode.
• After scanning, if the ticket is valid, the ticket information associated with it is displayed (Event name, ticket category, ID and/or name of the attendee if applicable). There is also an identifying OK sound. At the moment that information is displayed, the ticket is already considered delivered, so the next time it is scanned, it will be indicated that it has been delivered previously. If the ticket contains identifying data of the attendee (name and/or ID), the validator action is required, pressing the button to exit the ticket information screen. If no attendee information is displayed, the ticket information remains displayed for less than three seconds and returns to the scanning position so that the validation process is agile.
• You can also validate a ticket by manually entering the localizador, after clicking on 'Enter reader' and then on 'Check reader code'.
• If the ticket has been canceled, or is not valid for the user, or has been delivered previously, a message is displayed indicating the information. There is also an identifying error sound.
