Drankkaarten

A simple app with drink tickets each (youth) association.

Works on any simple / cheap / old / ... tablet.

Synchronization with multiple devices.

Easily manage all the drink cards within your association? It is possible, this app offers everything you need for that.

 - You can find all the drink cards on one device, which makes it easy to move them.

- Different prices for different drinks? No problem, you can enter all the different drinks. So you just have to indicate them. The app also keeps track of how many drinks are taken per type during a certain period, ideal for keeping up with the stick.

- With the use of Bluetooth you are not limited to that one device to be able to adjust the drink cards. You just use your own device, open the app and see a list of the drink cards without having to move to the main device. As simple as it can be.

- A total backup will be sent to these connected Bluetooth devices, so if you haven't lost the data, something had to be done with the main unit. Don't you use this bluetooth function? Then it is certainly advisable to make a copy of the data on a regular basis. The app saves this data in a file that can be found between the files of the device.

- The unthinkable has happened, the main unit has crashed / ... and the data is all gone. Fortunately, everything can be restored directly from the backup file. (for this you must of course regularly make a copy of this file, regularly connecting via bluetooth is the easiest, then the backup happens automatically)

- Has something happened by accident? No problem, a log is kept of everything that is done, so see immediately what would have been done wrong. And better yet, the app can undo this yourself, you just have to indicate until when the app needs to undo everything.

Before the installation starts, various permissions will be requested.

 - The right to write to an external SD (Photos / Media): this is because the app regularly creates a backup file in the memory of the tablet or an SD card in it.

 - Reading from an external USB memory: this allows the app to directly retrieve a backup file from a USB stick.

 - Camera: if the option in the app is to take a photo every time something happens in the app, it will be used, for something else the app will never use the camera. You are responsible for letting the other users of the app know if you use this.

 - Bluetooth: The app naturally needs Bluetooth if you want to use synchronization with multiple devices. If you do not do this, the app will not use the Bluetooth.

 - And the permission to prevent the tablet from going into sleep mode: This is for the main unit when the bluetooth is used to keep the app working. It will also only use this if the device is hanging on the charger.
