Android: Authenticating with NXP MiFare Ultralight C

由 左心房为你撑大大i 提交于 2019-11-27 03:43:12
问题 I have been trying for more than a week to make an Android phone authenticate with a Mifare Ultralight C. I have confirmed I can write to the tag (by writing to an unsecured memory page and then reading what I wrote). I can also write to the key pages (44-47) and have written 0x00 for all 16 key bytes. When I try to authenticate, the following is an example of the data involved during one exchange - it is from a log written by my application. Can anyone tell me if I am doing something

Serials on NFC Tags - truly unique? cloneable?

由 扶醉桌前 提交于 2019-11-26 17:26:44
So are NFC tags really UNIQUE from each other, at least in their SERIAL NUMBER ? And can we rely on the fact that no 2 NFC tags can have the same serial number? I'm highly skeptical about this as there are (and will be more) NFC tags out there and I don't think anyone is controlling the serials... The reason I'm asking is that I'm developing a key based system using NFC tags. I don't need to write to the tags, I basically just need their serial numbers. But I need them to be truly unique . Also, I would like to know if the serial numbers can be cloned (I know the content of tags can always be

Android and Symbian NFC mobile development questions and answers (FAQ)

问题 Let’s share on a common place ideas about the NFC development, technology… I warmly welcome any comments you might have – either about the Android or Symbian SDK or about the NFC in general. From my point of view the general question is what we can develop, i.e. what kinds of applications can we bring to the market with the NFC technology? And how can we, developers, earn money and benefit from the NFC? I think there is an expectation the NFC will open the door for numerous services and

Emulate Mifare card with Android 4.4

由 白昼怎懂夜的黑 提交于 2019-11-26 11:16:45
I have researched Mifare and other card emulation I have very good knowledge in programming (not Android, but C/C++). I have proxmark and I have made multiple emulation codes for proxmark, so I know how the cards communicate. I don't understand currently, does android enable full card emulation. I have researched this for about 3 days now, and the conclusion is there is no one constant pattern. Some people say it is possible, some say it is not. I looked through android API and the Host-based card emulation seems to be able to do the trick, but as I understand it is new thing in 4.4 Kitkat,

Reading NFC Tags with iPhone 6 / iOS 8

由 浪尽此生 提交于 2019-11-26 04:05:54
问题 Now that Apple just announced the iPhone 6 will have an NFC chip, does anyone know if iOS 8 will enable reading/detecting RFID tags for the iPhone 6 device? Anyone have any details to share on this? 回答1: The iPhone6/6s/6+ are NOT designed to read passive NFC tags (aka Discovery Mode). There's a lot of misinformation on this topic, so I thought to provide some tangible info for developers to consider. The lack of NFC tag read support is not because of software but because of hardware. To
