Hi there, thanks for posting! Are you using the ACS ACR35 driver or the Flomio SDK? Also, can you post your current code so that we can start to identify the problem.

Hi Stuart,

Thanks for your reply.
i am using sdk from this link
—–> https://github.com/flomio/flomio_android/tree/master/ACR35
I think this sdk is for acr 35.
I ordered a couple of flojacks v2 last year. Up untill now i only used the reader to get the Factory ID of the nfc card.

I am currently working on my project involving acr35 on android and Mifare Classic cards, to read data stored on them which are encrypted using diversify algorithm with our own Master keys.

I am facing issues at the time of authentication. Can you please help me overcome these issues?

i have got a sample app from the ACS website on which we are trying to work on.

Based on using the acr122U reader, I have tried to follow the same process for acr35 ( flojack v2 ).

The process we are following:
>> store key B in reader
command: FF 82 00 01 06 8B 4A 03 86 AE 22
Response–90 00

>> authenticate block 0C using keyB
command: FF 86 00 00 05 01 00 0C 61 01
Response–90 00

>> read 0C block (data block)
command: FF B0 00 0C 06
Response–63 00

>> read 0D block (value block)
command: FF B1 00 0D 04
Response–6A 81

On the command for reading, we receive a failed response ’63 00′.

This command is working fine with ACS 122U ,But not working with ACR 35.

*Also, even if there is no card present, I always get 90 00 response for the command for getting the UUID.

The mobiles Yureka and Micromax A1, have been tested on

Let me know if you need any code snippet from my side.Waiting for yr reply.

Hi Raj/ Stuart:

This is Khristine from Advanced Card Systems (ACS). I have seen the authentication issued you’ve encountered using the ACR35 reader and Mifare card.

May you try this command in reading block 0C – FF B0 00 0C 10.

May I also know if you have tried authenticating block 0x0D first before reading it?

Thank you so much!

Hello Khristine,
Thanks for reply ,

previously i’m using for reading block 0C – FF B0 00 0C 06. ( not working with ACR35 ) (but working with asc 122u)
now i tried your command in reading block 0C – FF B0 00 0C 10. that is working fine for read with acr 35

but now i’m trying to access (Block D which is value block) increment and decrement command : FFD7000D0501000003e8 which is working on acs 122u but not working on ACR35

and i also tried writing complete block using command : FFD6000D10000102030405060708090A0B0C0D0E0F that also working with only acs 122u also not working with acr 35

Hi Raj/Stuart,

Apologies for the late response.

May I know what return values you’re getting when you encounter the error for Value Block Operation and Update Binary Block?

Our engineer needs some information for investigating the issue so we may able to provide a solution.

Thanks again,
Khristine
