So I’m looking at alternative approaches. Most external USB based smart card readers are USB Chip Card Interface Devices (CCID). Has anyone used GHI’s USB raw device to communicate with such a device and is willing to share some code?
I’ve been doing a project with rfid/nfc with a fez spider and a non-gadgeteer rfid board with I2C. There is also a rfid gadgeteer module made by community member justin. More info on his board you can find here https://www.ghielectronics.com/community/forum/topic?id=8871&page=1
If you want more info about my project please ask.
I need to read NFC forum type 2 tags. But as far as I understood it it won’t be a big difference whether I read or write a tag as this is just a different APDU command that has to be sent to the card.
I use a Sony RC-S380 reader to write the tags using Windows 8’s proximity API. In addition, I use the same API on Windows Phone 8 to read and write.
I’m in Switzerland. That’s probably not nearby but would be great if you have a working module AND software. My problem is the software part. I already bought a module from dfrobot but that chip (MFRC500) is freaking complicated to use…
I’m using this module ( Cheapest MIFARE Module SL018 ) connected to an extender gadgeteer module. Justins solution wasn’t on time for me, but it will be for any future project.
I’m reading mifare tags for this project there is no need to write. I’ve done writing before it is almost the same as reading. The only thing with I2C is to get your timeouts right.
@ Justin: Do you have a spare module to sell? This looks interesting… I’m in London from Thursday to Monday. Does that help?
@ Patrick: This also looks nice. Did you document how to connect it to the extender and would you be willing to share your code? I have not much experience (almost no) in soldering and I’m bit worried of wiring it myself. After the MFRC500 experience I realized that the documentation standards in electrical engineering are even worse then in software engineering
