TIBADO Digital Coin and Atttributes

TIBADO emulates digital coins in the form of a digital image format file and can be easily communicated through various digital communication channels.

TIBADO's technology can enable a non-exclusive license which will allow the licensee to implement and create their own brand around a coin for their own exclusive product or digital currency system.


The TIBADO coin is identifiable with a distinctive 2D barcode and contains the security attributes when completing a coin purchase or transaction.

TIBADO's barcode design is not used like traditional barcode technologies and the design has been implemeted within the image and application structure itself, so a coin is worthless without a barcode value.

The client application runs its own routines to separate the coin template from the embedded barcode.
