Can it only read UID without input any key?

How am i suppose to build this there is only one build instruction of mvn clean install, no further information?

Hello,
Do you have any android sample to read/write NFC code.Please send me...

I have a problem with my ACR122.
All is ok, thanks to that page : https://www.latelierdugeek.fr/tag/mfoc/.
But i can-t copy the card because the terminal say : mfoc: ERROR: only Mifare Classic is supported
The card i want to copy is UID size double : myfare ultralight and mifare ultralight C so i need help to know how to deal with this.
Someone can help me please?

Does it support acr1252u reader?

Is this just writing an array of bytes, I don't see String anywhere?

--write S B KEY DATA\twrite DATA to sector S, block B of Mifare Classic 1K cards using KEY\n

I don't understand this line above.

Is the following an array of bytes which translates to what? Can I hold a string value in a card and how would it be done?

--write 13 2 FF00A1A0B001 FFFFFFFFFFFF00000000060504030201"

The app name is reader writer but from the help screen it is not clear how one can read in a card?

how write in NDEF format

When I try to write to the card nothing happens, on previous versions worked fine!

This is stupid i know. But I've been looking around for acr122urw.jar, didn't find it. Should i generate it from one of the java classes in the project?

How can i run it on windows?
How can i add support for another card like sri 512?

Hi. I couldn't get this project to work. The error is it can't detect the reader while I already plugged in USB ACR122U Reader. Looking at the pom.xml. Should I include the "com.acs.smartcard" library?

probably like this

<dependency> <groupId>com.acs.smartcard</groupId> <artifactId>acssmc</artifactId> <version>1.1.2</version> </dependency>
