windows phone 8 - Is it possible to perform multiple transactions with an NFC tag or device? (i.e. read more than once) -


according nokia developer's page, can read nfc tag subscribeformessage method: http://www.developer.nokia.com/community/wiki/use_nfc_tags_with_windows_phone_8

there 'tip' below read tag code:

warning: receive message, must perform subscription before proximitydevice.devicearrived event fired, or user must remove tag , repeat operation.

does mean cannot read nfc device more once windows phone 8?

as mentioned here in android api, nfc devices can used e.g. key generation, can useful make several reads , writes card.

as far can tell, windows phone 8 supports nfc forum formatted tags, i.e. tags contain ndef message. os read ndef message tag automatically , dispatch app.

this done part of proximity api, technology-agnostic , such hides nfc communication app. communication proximity device may take place on bluetooth or wifi; app not know (cannot know) , not have care this. there no way set connection nfc tag can in android.
