    <p>We are all a little bit lost about NFC Card Emulation in Android. Google and manufacturers are being a little bit too secretive about it. Engineers in charge of the API are IMHO playing a <a href="http://www.nfctimes.com/news/android-card-emulation-expected-despite-doubts-google-engineers">smokescreen</a> game. They claim about the <a href="http://www.nearfieldcommunicationsworld.com/2011/05/11/37352/google-raises-concerns-over-the-viability-of-nfc-card-emulation-mode-for-mobile-payments/">lack of interest in card emulation and they difficulties</a> developers could face, but the fact is that they want to keep <a href="http://www.google.com/wallet/">the hen of the golden egss</a> for themselves for the time being.</p> <p>No one knows a thing about SGII SWP capabilities. All are rumors. The same happens with Nexus S, which faces several problems. Obviously though applications could access embedded SE it would be worthless, since keys are expected to be kept secret by Google. The only way to go is the hope in SWP connectivity between UICC and NFC controller. Theoretically it is possible, and it has supposedly demostrated by Dr. Madlmayr <a href="http://www.madlmayr.at/blog/?m=201102">at last MWC</a>. However I am a bit skeptical about his success taking into consideration that without the manufacturer's cooperation, regarding baseband firmware support on SNS or SGSII, sending APDUs to the UICC, that <a href="http://groups.google.com/group/seek-for-android/browse_thread/thread/661c8fd380d8f832">seems not yet supported</a>, card emulation through UICC is a lost war.</p>

    1. CO1) I did some more investigations on the topic regarding the micro SD card support over the S2C (NFC-WI). The SD Card association standardized the 2 antenna pins in the same time ECMA standardzied the NFC-WI - but I do not know about any SD card with antenna PINS plus I am not aware about the SD card slot in any phone that is connected to the RF antenna in order to get the signal to the SD card secure card controller, which will allow the micro SD card acting as an ordinary contactless payment card.

    2. CO2) For the Java application developer I cannot see to much space in NFC payment area. One part of the application will be done in JavaCard and uploaded to the secure element leaving to the application developer possibility to communicate with the cardlet on secure element on over the APDU to get data to display in user interface 'less secure' data like 'list of last 5 payments', daily spends graph, etc... does not look that interesting:)

    3. CO3) The use of the SmartMX on the Google phones will be probably only for selected partners in specified regions, phone manufacturer or Google itself - that's for sure. The only way will be UICC and SD card, while the GSMA and MNO will probably force phone manufacturers to not go the micro SD card way... which might be the opposite banks would prefer...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
