I know it's not possible for the iPhone 6 to read RFID tags, and I know that the iPhone API only allows use of NFC for Apple Pay, but is it possible to read an iPhone's NFC chip as if it were an RFID tag? That is, would an RFID reader be able to retrieve any sort of passive information like a chip's unique ID or something of that nature, by using an RFID reader with something like an Arduino or Raspberry Pi? It appears that it is possible to detect the signal coming from the iPhone when you hold down your thumb to attempt an Apple Pay payment. However, it sends out a different ID number with

I have a problem trying to authenticate an Ultralight EV1 card using a PC/SC reader (specifically an ACR1222L) in Java. I'm able to write and read on an unprotected tag using the corresponding APDUs for ISO 14443-3 tags. However, I can't find a way to run the PWD_AUTH command since it is not part of the 14443-3 standard (or any native command for that matter). Is it possible to run this command (or any native command for that matter)? I have tried sending the following APDU {e0 00 00 24 07 1b ff ff ff ff 63 00} where 1b is the native command, ff ff ff ff is the password and 63 00 is the CRC_A

My question is for feedback on making sure I am taking the right approach, and handling the threading correctly. I have a feeling I may need to set of some of my own threads, so all feedback is welcome. The problem I have is reading RFID tags from zero or more RFID readers. I can read for a single reader without an issue so reading from several will not be an issue. Each Tag or batch of Tags read by the reader is delivered by a .Net Event. My plan is to setup a ReaderControl class, which maintains the readers, connection, starting, stopping, etc. This class will listen to the TagRead events

RFID射频识别技术 RFID（Radio Frequency Identification）俗称无线射频技术。 作为构建“物联网” ，进行数据连接、数据交流的关键技术之一， 无线射频技术 是20世纪80年代发展起来的一种新兴自动识别技术，利用射频信号通过空间耦合（交变磁场或电磁场）实现无接触信息传递达到识别目的。 工作原理 电子标签(Tag)进入磁场后，接收读写器(Reader)发出的射频信号，凭借感应电流所获得的能量发送出存储在芯片中的产品信息（无源标签或被动标签），或者由标签主动发送某一频率的信号（有源标签或主动标签），读写器(Reader)读取信息并解码后，送至数据管理系统进行有关数据处理。 衍生产品 无源RFID产品 该类产品需要近距离接触式识别，比如饭卡、银行卡、公交卡和身份证等 主要工作频率有低频125KHZ、高频13.56MHZ、超高频433MHZ和 915MHZ 有源RFID产品 该类型产品具有远距离自动识别的特性，比如智能停车场、智慧城市、智慧交通及物联网等领域 主要工作有微波2.45GHZ和5.8GHZ，超高频433MHZ 半有源RFID产品 结合有源RFID产品和无源RFID产品二者的优点，在低频125KHZ频率的触发下，让微波2.45G发挥优势，近距离激活定位、远距离传输数据 比如在门禁出入管理、区域定位管理及安防报警等方面的应用 优缺点 优点 抗干扰性强

Is it possible using ATR to determine whether I have ISO14443A or ISO14443B type card? If yes, how? Michael Roland As mictter correctly explained , a real AT R only exists for ISO 7816 contact cards. I can follow the argumentation that the ISO 14443 equivalent could be the ATQA/ATQB as this is the first answer you get from tags after activation, though I would rather say that the equvalent of the ATR is a combination of ATQA + SAK + ATS (for Type A) and a combination of ATQB + Answer to ATTRIB (for Type B). Regarding the ATR you see, I assume that this is a PC/SC-emulated ATR according to the

This question is specifically about MIFARE Ultralight C/EV1, or MIFARE DESFire EV1, or even NTAG cards. I want to implement a system of tokens, so that each time a normal user reads one of those cards they'll get one available token; that token will "pop out" from the NFC card they're reading. In other words, every time that NFC chip is read, it will issue a different usable token from the card's storage. Is this possible to implement? Common non-programmable smart cards usually provide one of (or some combination) of the following: fuse bits -- a memory area where values of individual bits
