Q:What is Qreca!

A: QReca! is a tool for building mobile web applications. It provides a user friendly interface and the main characteristic is that it hides all technical details. Thus, it is appropriate for users with no IT skills. The basic feature of the platform is the presentation of information, that is combined with extra functionality. One can think of QReca! as an empty canvas, where a user can place various micro components (Items) we provide, without having any IT knowledge. Those micro components are the extra functionalities the user wishes to add to his/her web application. The desired web app eventually is produced, by assembling those independent Items into an integrated Collection.

The application can be triggered via a QR Code. Moreover, the user may change the information and the functionality that are associated with an app without the need of reestablishing the access channel (e.g. reprinting the QR Code).

Q:What is the QReca! backend?

A: The QReca! backend is the working environment to which you have access as soon as you login. In the backend, you can manage your personal information, your Collections and Items.

Q:QReca! world unveiled: Handlers, Collections, Items

A: In the QReca! world there are three basic entities that are provided by the platform. The understanding of these notions is crucial for efficiently using the platform. There is no need for someone to be an expert so as to perceive this concept. They are not technical entities, rather organizational and assist the better management of the information. The aforementioned entities are:

  1. Handler
  2. Item
  3. Collection

The goal of using the QReca! platform is to create web apps. A QReca! web app is a Collection, and is triggered by scanning a QR code. It is created to serve a specific goal. A Collection may consist of different Items, leading thus to a multiple functionality, depending of the discrete functionality of each contributing Item. The Item can be considered as a template that is filled with information. This template, apart from the presentation layer (information presentation) may also exhibit some functionality. The QReca! user that creates an Item, actually fills the template with the information he wishes to share (either in the presentation layer or through the functionality of the Item). Finally, a handler can be regarded as the empty template mentioned earlier. Item and handlers are similar notions, in the sense that an Item is an instance of a handlers (i.e. handler filled with information). Handlers are developed by experts and are available to non technical users to use them so as to cover their needs. They are more abstract, so as to have a more general use, and are customized by users when they create Items.

Q:How can I create a Handler?

Q:Why should I use a Handler?

A: For the time being, only certified users can create Handlers. Contact us for more details.

Q:Why should I create a Collection?

A: The QReca! Collection is actually the web app that you wish to develop. It is an integrated entity that consists of one ore more Items. The QReca! Collection is the web page that is viewed when a QR code is scanned.
