Use a Magic NTAG213 card and change UID when it is empty, or use cheap NTAG213 stickers and just take a new one when the old one is empty.
It's possible that you can actually start re-using (re-filled) NTAG stickers after a while, since the internal memory of the Mini only stores ~100 last UID used. I haven't tested this.

Thanks for response, and new UID for new sticker may be just random?

Yes. It comes pre-programmed and you cannot change the UID.

Ok, and which value must be in page 43 (where is stored password for tag)? Because seems it is on UID depend.

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

Thank you. So, my last unknown is how to generate first two bytes in page 02, which are a checksum generated from the serial number. Thanks for your patience smile

I'm note sure you can/should change page 02, but they should be:
XX480000
where XX is checksum of page1.
To calculate the checksum, XOR all four bytes in page1.

The Mini / Mini W / miniMaker do NOT accept re-filled tags, regardless of firmware version.

As you were told, you cannot 'refill' the nfc card on your machine.  You machine will remember how much is on it and will not accept it if the nfc suddenly reports more filament that what was on it.  You do have options:
1- Swap the nfc card with someone else.
2- Remove the eeprom that is on the motherboard and erase / replace the eeprom.  This will allow refilling.  Search forum for details
3- Use Rhys's emulator.  This will replace the whole NFC system in the mini
4- Use EMUtag - this will all you to program the EMUtag with new UId / PW / PC
5- Use cheap nfc stickers and program them with new UId/PW/PC - not sure I have seen details on how to do this yet.
EDIT:
6- As Mr Clown pointed out below, . You can purchase one of these http://www.soliforum.com/post/139685/#p139685  Just make sure that you understand fully how to use it "BEFORE" you purchase it.


I use #3 in my Jr.  Works great.  I did use #4, but in my opinion, #3 is better.

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

OK, thank you for answer.
When I'm reading tag with android program RFID NFC Tool, so tag is readed to the page 2B (that is page 43 dec), but on the page 44 should be PACK number stored. Why is tag readed only to page 43? Will I be able to write page 44 using this program? Or what program are you using for creating a new tag?
Thanks a lot and I'm sorry for my beginner questions...

Re: XYZ Printing Da Vinci Jr (w) / Da Vinci Mini (w) Hacking

You will not be able to update the Pack Code on any tag except one that is re-writeable in all fields.

Those would be options 3, 4, 5, and 6 in previous post.

Do you have URL of Rhys's emulator page, please? I can't find it. Thank you.

Yes, I agree with yizhou.he as far as the price goes. The cheapest solution at this point are the paper stickers. If you cannot use modified tags. You will need a different one each time your tag goes to zero length. Those things are so cheap that should not make a difference though. Just make sure you have the hardware that willl allow you to update the password and Pack Code. I believe I have read on here somewhere some of the Android apps will not allow that. I cannot say I am 100% sure as I do no have an Android that is NFC capable.

Yes, you will.
Only UID is locked. With correct key you can change key and PACK on the tag (sticker).

Thank you for the correction. I guess when I said "any tag except one that is re-writeable in all fields" that was mis-leading. wWhat I should have said was any tag that has updatable Password and Pack Code. My second statment did include the stickers as a viable option to use though. Sorry for the confusion.

each paper sticker have different id? have anyone tried to find out what's the maxi number of tag jr. can remember? space in eprom are expensive, I can imagine there is a limit number of tag it can remember, depends on how firmware deal with the overflow....

Yes. The eeprom dump reveals it could probably remember 108 UIDs.

My real question is what happens after it read 108 UIDs, it will stop recording or delete the first record or delete the last record, 108 paper sticker still quiet expensive, but how it handle the 109th UID may leave room for possible hack.

It's weird - page 00h and 01h is read only, that's right. But I can't modify page 02 too. Any ideas, please?
