ACR122-卡仿真 [英] ACR122 - Card Emulation

问题描述

如何使NFC非接触式读取器ACR122U充当标签(卡仿真模式)? 招股说明书声称该设备可以进行卡仿真，但是SDK似乎没有提供此功能的示例或文档.

How can I get the NFC contactless reader ACR122U to behave as a tag (card emulation mode)? The prospectus claims that the device can do card emulation, but the SDK does not seem to provide an example or documentation for this feature.

有人知道该怎么做吗? 是否需要其他软件? 请注意，我的目标平台是MS Windows.

Does anybody know how to do this? Is there additional software required? Please note that my target platform is MS Windows.

预先感谢

推荐答案

有关卡模拟"或换句话说，配置为目标并等待启动器"，请参见此处:

For "Card Emulation" or in other words, "Configure as target and wait for initiators", please refer to here: http://code.google.com/p/nfcip-java/source/browse/trunk/nfcip-java/doc/ACR122_PN53x.txt

** Command to PN532 **
0xd4 0x8c TgInitAsTarget instruction code
0x00 Acceptable modes
(0x00 = allow all, 0x01 = only allow to be
initialized as passive, 0x02 = allow DEP only)

_6 bytes (_MIFARE_)_:
0x08 0x00 SENS_RES
0x12 0x34 0x56 NFCID1
0x40 SEL_RES

_18 bytes (_Felica_)_:
0x01 0xfe 0xa2 0xa3 0xa4 0xa5 0xa6 0xa7
NFCID2
0xc0 0xc1 0xc2 0xc3 0xc4 0xc5 0xc6 0xc7
?
0xff 0xff System parameters?
0xaa 0x99 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
NFCID3
0x00 ?
0x00 ?

这是启动器激活此目标时的响应:

This is the response when an initiator activated this target:

** Response from PN532 **
0xd5 0x8d TgInitAsTarget response code
0x04 Mode
(0x04 = DEP, 106kbps)

让我知道它是否有效！
