BlackBerry NFC API target.getUri(Target.ISO_14443_3)返回的结果

测试下来，每种卡片只能正确响应一种连接类型。

测试结果如下：

==============================================================================

Mifare Ultralight（华虹）

BlackBerry API target.getUri(Target.ISO_14443_3)返回的结果：

nfc:raw:33554556

能建立ISO14443Part3Connection连接，发送0x30读指令读到数据

==============================================================================

Mifare 1K（华虹，淘宝），Mifare 4K（北京淘宝）:

BlackBerry API target.getUri(Target.ISO_14443_3)返回的结果：

nfc:raw:33554556

能建立ISO14443Part3Connection连接，但发送0x30读指令后报错Error exchaning ISO14443-3 data: UnExpected error

==============================================================================
Desfire 4K（北京淘宝）:
BlackBerry API target.getUri(Target.ISO_14443_4)返回的结果：

nfc:iso14443:33554473

能建立ISO14443Part4Connection连接，但发送0x30读指令或者0x60认证指令后返回结果总是两个byte -- 9700，看样子是Desfire不认这两种指令。

==============================================================================
Mifare Ultralight空卡/有智能标签的卡:
BlackBerry API target.getUri(Target.NDEF_TAG)返回的结果：
nfc:ndef:33554502

无法建立连接(连接为空)

• ISO_14443_3 covers ISO 14443, A-3, B-3
• ISO_14443_4 covers ISO 14443, A-4, B-4
• NDEF_TAG covers NFC tags type 1, 2, 3, 4
