New to openpcd and some questions

[Sebastian Hammerl]

Hi,

i am new to the whole rfid scene and got an openpcd cardreader and now
have some questions:

1) Is it possible to read/write on cards with mifare-tool without root
permissions?

2) I accedently have overwritten an access block with 0000...00 so i
don't can do anything more with this 4 blocks. Any chance to reset it to
factory default or something else?

3) Is it possible to read out more then one card, when more than one
card is on the reader? when o put two cards on it, i only get one of them.

Thanks for your help in advance, Sebastian
