Upgrade available from EVA

The latest version of the EVA-DTS (version 6.1) has just been approved by the EVA and NAMA. The new standard has been updated in order to support mixed payment where the required funds are provided via cash and cashless systems.

The latest version of the EVA-DTS (version 6.1) has just been approved by the EVA and NAMA. The previous version, 6.0, was launched three years ago. The new standard has been updated in order to support mixed payment where the required funds are provided via cash and cashless systems. It also clarifies the handling of discounts and surcharges.

The fundamental protocols of the EVA-DTS standard have been preserved but additional information and explanation has been provided to aid implementation and remove ambiguity.

The new version makes sure that in those situations where the consumer’s cashless card has insufficient funds to buy the desired product, the card-user can top up with cash. Also, a vending machine may allow different product prices defined by user groups or during specified time bands. In this case, the vending machine uses additional price lists to those previously configured for cash and cashless vends.

The standard specifies the form of the data elements and the protocol for transfer to and from a vending machine (or other source), and a business system. In preparing EVA-DTS Version 6.1, recognition has been taken of alternative methods of transferring data (e.g. remotely via some wireless means). The intention is not to limit the design flexibility of manufacturers of vending machines, payment systems, data carriers, business systems or other technologies for transferring data, but rather, to provide the basis for compatibility between the elements.

Version 6.1 of EVA-DTS seeks to encourage a wider application of the standard by simplifying the task of potential implementers. It is aimed to achieve this by guiding the implementers of new applications to the essential elements of the total system, which is of relevance to them. The new elements are required if cashless and pricelists are used. If not, the old elements can still be used.
