smartcard-reader

问题 I have an an old NFC reader for the tikitag web service (which was later renamed touchatag, and finally abandoned around 2012). Since the website is no longer available, I could no longer find the original tikitag/touchatag drivers. After some searching, I found this NFC reader is a generic ACS ACR122U USB reader, and installed a suitable driver from here. My system is Windows 7 (64-bits). First, I tried the NFC Tools library for high-level read and write access to NFC tags. I got an error

问题 I have a ACR38 samrt-card-reader and a number of Javacard [2.1.1] compliant with GP Spec [02]. As I know, there is two kind of APDU, Short-APDU [APDU with LC or/and LE shorter than 255 ] and Extended-APDU [APDU with LC or/and LE greater than 255 ]. is that right? We send Short-APDU in T=0 protocol and send Extended-APDU in T=1 protocol. is that right? I sent Short-APDU to my card successfully. [via GPJ , GPShell , OpenSC-Tool ]. And now, I want to know: 1: if I want to use Extended APDU, my

问题 I have a terminal that has its own API to stablish and send commands between chip and terminal, there is a function that transmits the APDU command and returns the answer in a byte array. For example, if a want to read the tag 5A (Application PAN), I send the following command: byte[] byteArrayAPDU = new byte[]{(byte)0x00, (byte)0xCA, (byte)0x00, (byte)0x5A}; int nResult = SmartCardInterface.transmit(nCardHandle, byteArrayAPDU, byteArrayResponse); The variable byteArrayResponse gets the

问题 My project I am working on a small program which has to set an alarm if the user locks the computer without removing the Smart Card from the computer. I am using C# with WPF and .Net 4.0 and my smartcard is version V4.2C My problem I have all the functionality to work but I simply don't know how to detect if the Smart Card is in the Smart Card Reader. I have tried to search on google but with no result so I hope some of you can help me. 回答1: Well, if I google for "C# smartcard" the first link

问题 I'm trying to pass though APDUs command via HID OMNIKEY 5427 CK to operate MIFARE Card ie. Ultralight C card, on the Windows 10 x64 OS environment using WinSCard.dll. (I'm under NXP NDA and have full access t their documents) I tried to find information online for days now. Seem like no published document for this model except the 2pages brochure. The simple command like GetUID (FFCA000000) is OK, I can get back the actual card UID. But for 'Authentication with Card', reference document from

问题 I have succesfully retrieved the CVM List from EMV card. 0000 0000 0000 0000 4103 4203 1E03 1F02 From the EMV specification book 3, the first 4 bytes and second 4 bytes are amount and rest is CV rules. Making these the CV Rule 4103 4203 1E03 1F02 The book also shows how to parse the CV rules, as shown below: I am assuming that I need to convert the first two bytes in a CV rule to binary and match with the table above? But why does the table above have empty cells? Also can someone explain in

问题 I want to use my ACR122U contact-less smart card reader in Ubuntu 14 smarty. So I installed my required packages and drivers. Finally when I want to use the reader I receive the following error: rc@rc-System-Product-Name:~/Desktop/itsme$ sudo nfc-list [sudo] password for rc: nfc-list uses libnfc 1.7.0 error libnfc.driver.acr122_usb Unable to claim USB interface (Device or resource busy) nfc-list: ERROR: Unable to open NFC device: acr122_usb:001:020 rc@rc-System-Product-Name:~/Desktop/itsme$

I'm using pre-define AID, which i have googled to be valid (correct me if i'm wrong). here's the are : AID_LIST = { "A0000000421010", "A0000000422010", "A0000000031010", "A0000000032010", "A0000000041010", "A0000000042010", "A00000006900", "A0000001850002" } Thanks in advance. 回答1: I am not familiar with this API you are using, but you will have to send the following sequence

问题 I am trying to read information off of a smartcard, using a contact-less OmniKey 5321 card reader. Edit : Added a bounty. I'm writing a C# 3 in .NET 3.5 program, so this is a Windows application. The card has some information stamped onto it, that I would assume, in some way, is present in the card data (there is a photo of the card and reader below.) The card has the following information stamped onto it: 1* 00447 21091328-32 When using the Diagnostics application that comes with the OmniKey

问题 I use WinSCard to list all readers, which gives me a list like this: ASK RDR4x7 0 SCM Microsystems Inc. SCR3320 USB Smart Card Reader 0 SCM Microsystems Inc. SCR3320 USB Smart Card Reader 1 SCM Microsystems Inc. SCR3320 USB Smart Card Reader 2 Which is great, but I have no clue which name belongs to which card reader. Where do these names come from? How are they constructed? What I've found up until now: in the registry, there is a HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services key.
