Off topic, I know, but there is growing availability of contactless interface cards, and growing interest in using them in both transport and citizen card applications areas. And, apart from the products discussed in this thread, there are major developments by Japanese suppliers, apparently targetted at e-commerce and citizen ID card markets.
Mifare Pro and ProX have the ability to configure the contactless interface in different ways according to the ROM software support code included in the OS. The contactless interface is either Mifare (but perhaps up to 4K bytes, rather than the 1K bytes of the basic Mifare Classic memory card), or some other protocol designed by the OS owner. Typically these days, the 'other protocol' is T=CL as described in ISO/IEC 14443 Part 4. T=CL is similar to ISO/IEC 7816 part 4's T=1 protocol, and the intention is that 14443-4 is a bridge across to 7816 command structure. Where the Mifare mode is used, whether there is internal communication in the card between the contactles interface's memory area and an application running in the contact interface area is also something for the card OS to implement. Schlumberger has Mifare Pro products, with one version having Mifare on the contactless interface, and the other having 14443-4 style commands. They may have a ProX product by now (ProX has a more powerful CPU than Pro, and extra crypto functionality in the silicon). IBM has recently launched an early version of their JCOPS OS on the Philips ProX dual interface silicon, and this OS is believed to have an internal configuration option to allow it to be switched between Mifare compliance and 14443-4 compliance on the contactless interface. This probably has to be configured at personalisation time. It is also reported that the current version of this OS has not implemented the internal link between the contactless memory area and the contact memory area when the Mifare mode is used. This card is available from Orga, plus (I think) from another supplier whose name I forget. There is also an announced project to implement Multos on the ProX, but probably with the contactless interface in Mifare mode only. An OS on the Infineon 66 series dual interface IC is offered by Setec Oy of Finland. STM's ST19 dual interface version had an OS for it implemented by Motorola's now closed WSSD. ERG and ASK have taken over the product, known as the Venus card. The contactless interface is ISO/IEC 14443 Type B (i.e. not Mifare). As for standards, to update the information below, ISO/IEC 15693 is the Vicinity card standard, operating at up to about 30 cm. 10536 is the now almost obsolete close-coupled standard (1cm), so widely drawn that a large number of different implementations can be derived from it. 14443 is odd. It incorporates Type A (air interface, anti-collision and initialisation as for Mifare, i.e. under licence from Philips) and Type B (different air interface, anti-collision and initialisation, designed in an open manner, i.e. no licence required). Also compliance only requires implementation of parts 1 to 3 - after that, you can either opt to use a proprietary protocol (such as is used by Mifare in the Type A family) or T=CL (defined in 14443 part 4). Unfortunately, if you use a proprietary protocol, 14443 does not define a method by which the card reader can uniquely identify which protocol is being used! Infineon has other contactless products as well as the dual interface 66 series.

That is a 2K byte memory card.
