Can anyone confirm whether or not the nfc chip in the n20u can successfully write to the 0 block of a mifare classic 1k chip or card if the card is a "magic" writable one.

Hi everyone.
Today my 2gb sd memory card's body broke and I took out a tiny microchip.
Now I'm wondering if I will connect it paralell to my sd wlan card somehow will something get broken or they can really work together possibly.
Any comments are welcome.
Cheers
Not sure, but I think with proper wiring (not sure if it will work just by simply paralel-connecting them) there should be a way to do so.
The Prophet, indeed, shows the built in Wifi network card, as "SDIO Wifi".
I guess they just put a SDIO WIfi module and wire it to the SDIO slot, but still can provide the SDIO slot free for memory card.
I want to add another SD card slot so that I can access an additional memory card while I have my WIFI card in. Assuming that the connector has the same pins as documented here, is there a way that I can communicate over the RX/TX pins? I would like to be able to connect a mcu to the pins and talk to it with a program on the phone.
hi sd experts.
i am trying to use an sd to microsd adapter mainly to connect my digital camera (sd card) on the road to my samsung galaxy i9000 (microsd slot). the adapter is built into a slightly bigger case of a 3000mAh battery.
problem here: the phone doesnt notice a card change in the sd slot. remounting is somehow "hardwired" to physically inserting/removing something from microsd, which does obviously not happen in my case.
manually unmounting/remounting the card from settings menu also doesnt work when changing sd cards in the adapter. android probably keeps thinking that you re-inserted the same card when nothing is physically pulled from microsd-slot. so if you remove an sd and insert another and try to mount from settings menu, it will either fail or mess up the file system.
what can i do to make this work? any unix commands to call to properly trigger a remount, just as when something is physically removed and inserted from microsd slot?
thanks,
joe.
somebody suggested to switch the microsd driver from handling card changes via interrupt to polling mode. anybody tried that? on my galaxy i believe it's in /sys/bus/platform/drivers/s3c-sdhci/
then there's a s3c-sdhci.0, a .1 and a .2 directory. which one would be the external microsd slot? and would adding a file "polling" with the contents "1" work for switching? does the android sd driver support polling at all?
so many questions but no answers... i guess nobody ever tried something like this on their phones
I have a mango card for use on buses. I was wondering if it would actually possible to take the details off this card and then emulate the card when i go on the bus so that my phone is giving the same details so it works on the bus?
Hello,
I have a school library NFC card which I use to open library doors.
Is it possible to copy the contents from that NFC card to a NFC tag and use the tag
the same way?
The NFC card is Mifare Classic and has Factory default key (not sure whether it is important to mention).
If I understand correctly, I will have to crack the secret key in order to have full access to the NFC card contents
and thus be able to make NFC tags?
What methods are used for cracking this key?
