I am starting with RFID and NFC, I have an ET50 Zebra Tablet with windows 10 and I am trying to read and write in a MIFARE Ultralight NFC card, I am using a code that I downloaded from:
https://github.com/andijakl/ndef-nfc
But till now no luck, after researching a lot I found that Windows only can read from NFC NDEF cards, so I confirmed that this MIFARE ultralight card fits that requirement and it is correct. I was also checking windows documentation and it seems that the device is only reachable by using Proximity Device Class. I did try to implement that but again no luck detecting the card.
Any help will be appreciated.

There was a requirement from a customer that they want a solution to upgrade the firmware of the HID OMNIKEY 5427 CK Smart card Reader remotely from an embedded device on which it is connected to. The embedded device runs Windows CE OS. They want a solution that runs on the embedded device and upon need they want to upgrade the firmware.
I read from the HID global documentation that this can be done in 2 ways.
Via a web server that starts when you connect the card reader to your Windows PC.
Via APDU commands in CCID mode.
It seems like the first option of booting a web server in the embedded device looks like a vague approach.
So, I am currently focusing on the second method of sending APDU commands to the card reader via CCID mode.
Does windows CE support the APDU communication for smart card readers? If so, is there some specific dll that I have to utilise and the corresponding APIs?
I am very new to this smart card environment and If you people could help me with some pointer, it will be greatly appreciated.
Thanks in Advance.
So I downloaded Android pay and got it setup with my card only to find that my phone doesn't have NFC. How I missed this, I don't know.
I was thinking this: could you put and NFC tag on the back of the device and somehow rig it to work? If not, would it be possible to get NFC hardware to work with a device that doesn't have it?
You can attach external NFC readers via USB or audio port. Technically, these would not be drop-in replacements, so you'll have to go with special apps which make use of the readers.
I'm working on the iOS app to interact with Arduino boards. On Arduino side i use "transparent" serial implemented in HM-10/11 firmware. So i just wire HM-10/11 RT/TX pins with Arduino ones and it works just perfect and write to specific characteristic to send data and subscribe/read to some specific to read from BLE module. No need to use any SDK or BLE library in arduino sketch, no need to modify bootloader.
Now i need to support NRF51822 BLE chips. Nordic has implemented UART serial in firmware sources but for my NRF51822 board (purchased on ebay) it's not uploaded to the chip by default as i can't see 0001 service and 0002 and 0003 characteristics. Do i need to purchase NRF motherboard and compile and upload this firmware? Can i do it without purchasing this dev kit? Can i upload over USB only or over BLE too?
If your are using NRF51822 standalone module ,then to update its firmware through SWIO/SWCLK pins ,you need a compatible JTAG programmer/debugger (you can check in segger website) . You can use Keil IDE to upload your updated firm ware to the flash memory of NRF51822 .
Although you need to upload using a SWD programmer, you are not limited to Segger.
There are open source alternatives like the Black Magic Proble which you can flash into $5 hardware (stm32f103 boards) from ebay.
You are also not limited to Keil or IAR for your compiler toolchain.
Its possible to compile using Eclipse and GCC ( Nordic have a blog entry in how setup an Eclipse base dev environment)
You can even program these devices using the Arduino IDE.
It is possible to upload OTA, but you would need to flash an OTA bootloader onto the device first using SWD and even then, you would probably need to upload via a mobile phone, as Im not aware of any PC ble devices that support transfer via the DFU protocol ( though some may exist)
These devices do not natively support USB.
Some boards using these device have a separate processor that allows upload as if the chip was a mass storage device, but I am not aware of a motherboard into which you could plug this module, which has that functionality.
BTW. The module you linked to, is actually designed and manufactured by Waveshare.com . Take a look at their website, it has full documentation on the hardware including schematics
The nRF51 and nRF52 dev boards has an onboard Segger / JLink. So then you can develop on and debug on the nRF51822 and flash other nRF51822s as well.
I'm looking to write a simple beginner program using Java Card to run on sim cards. Can anyone point me to some very basic information on getting started? I've seen some descriptions of the toolkit api, but I'm looking for things like: what capabilities are supported by the sim card, how to upload my code to the card (do i need special hardware?), how do I tell whether a sim card supports java card, that sort of thing.
EDIT: I'm specifically looking to run code on sim cards. I've seen some very high level tutorials online, but nothing that goes as far as connecting to a sim card or uploading code. I have a USB sim card reader and a variety of cards to test, but I can't find any detail on how to work with them.
To upload your code to a sim card, it seems to require one of these tools:
GPShell from the GlobalPlatform project
JCardManager which is part of the Gemalto Developer Suite
SIMAlliance CAT Loader
I've not got any of these to recognise my ebay sim card reader, so I think I'll have buy a different reader (probably from gemalto)
Edit: I bought the ACS ACR38 SDK, which includes 3 card readers and a selection of cards, along with drivers, code samples and tools. These card readers are working nicely with the Gemalto Developer Suite.
The Usability Lab tutorial provided with the Gemalto Developer Suite is a pretty good way of diving into sim card development.
Very interesting thing to note: it's pretty hard to get your code running on commercial mobile network operator SIM cards. They typically require the correct certificate before you can write to them.
There are hardware workarounds to this. I'm currently investigating TurboSIM and RebelSIM.
I finally gave up on this project due to other pressures. I was not able to get any Java Card running except on the dev cards, which are not compatible with real devices on a mobile network. The cutout cards such as TurboSIM and RebelSIM are a possibility but quite frustrating to work with.
there is a nice quickstart tutorial on the netbeans page

I am looking at integrating a C# application with a barcode scanner.
The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable.
Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry.
Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?
There are a number of Ethernet and Wifi code readers on the market, though they tend to be targeted at industrial applications and usually cost more than the USB models. The company I work for makes such readers, and our fixed-mount DM200 reader is just such a device.
You could use a small computer (or even a microcontroller) with RO media, USB, and networking capabilities plus a psu to turn any suitable scanner to a network one. Raspberry Pi, for example, could do it and seems to be hip these days.
Alternatively some portable devices (like Android tablets) could probably use a camera or even a USB scanner for scanning codes and come with capable networking features.
