Nevertheless the ability for the system to accomodate other smartcards become difficult. The need to use the relevant card readers might confuse some mobile users. By not using some of the intellegent features of the card readers it is possible to have cross brand smartcard - card reader operations. There are experimental software for such operations, e.g. GemPlus GCR reader with De La Rue DX card. Some of the interface standards are also appeared to be platform dependent and so adoption of a single smartcard interface standard is not possible at this stage.
Some standards cover more functionality than the other.
It will be used in the MS Windows NT 5 and so it will be a dominant standard. The OpenCard Framework is defined for the Network Computer and it will have the attraction of having a Java implementation. Irrespective of which interface standards is adopted, the main concern should be transparent operation to the end users.
