Can I use my Nexus S NFC to read OPUS

---

Here in Montreal the subway transportation card is called OPUS and is based on the MIFARE system. Can I get an app to at least dublicate the card so I don't have to card the OPUS with me?

I'd like to know that too.

Why has my messages been deleted ? Anyway, bump.

That would be awesome. Did you have any news from that?

what is nfc?

Near Field Communication (or Communicator)
Basically like a Direct WiFi to WiFi from a device to another device. If you ever used a transport card (Here in Montreal, it's called OPUS) to validate your entry to the bus, well that uses NFC. Thing is, these devices are hard coded and "almost" impossible to crack without the official source.

By default, the NXP PN53X controller in your Android device doesn't support Mifare Ultralight card emulation, though it does support Mifare 1K and FeliCa. The OPUS cards are Mifare Ultralights. Your best bet for card emulation is the OpenPCD2 reader. This piece of hardware has a ARM processor instead of a Secure Element, so you can write firmware and feed it directly to the PN53X NFC controller

Read Mifare Classic Cards?

A couple of things 1. The OPUS card AFAICS is based on Mifare Classic. 2. My Nexus S "reads" the card but can not decipher it i.e It can't tell me basic info like rides left, who the card belongs to (I asked them to encode my address in case I loose it"
3. STM uses disposable Mifare Ultralight Cards for the "occasionnelle" user; these too are "readable" and according to the read out "Formatable" but all attempts to do so fail.
4. I read somewhere about being able to to more with the NFC controller if you plug it into a PC and use the ADB SDK

Can anyone verify this info....Thanks.

Does anyone know a good Youtube video with NFC demonstrations?
