Sorry for the delay.
No, You just “overwrite”
It depends on what you are try to do.
If for example you wanted to send somebody to a youtube video
You would set that URL in the new dataset.
Then you don’t need to use an NFC app to read the URL, they or you would just scan your xSIID and it would launch on their phone if they had YouTube installed on their phone( Or ask what browser you wanted to open YouTube in )
Does that make sense?
No probleme and okay just overwrite and i just tryed by writing my contact info to the tag just my number and e-mail and the overwrite worked but it doens’t show op outside the app
Are you writing “Business Card” dataset?
When I scan Mine, My phone “asks” what I want to do with it…ie. Import as a contact, and in my normal contact list of Secure contact list
Yes thats wath i did but my phone wont read it . The led is working .
I have reached the maximum number of messages the url doesn’t work
Oh, incase you are trying with you phone locked, make sure your phone is unlocked when you are scanning it…
Can you try and write a url to it, and scan it again?
Hey im back sorry for the long wait . i tryed with the url but it doen’t show up when i scane it without the app
Can you please can using taginfo app, five us a screenshot of the full scan page. If it makes you feel better you can hide block 00 and 01 as thats your UID
YES!
Ah ha!
Right scan your tag if nfctools (dosnt need to be the pro version), and post that to again block the uid. I just want to be sure before I tell you what to do.
Right I know exactly how to fix it, as I accidently did this last night!
Download NFC shell while I write up what to do!
Paste this into it exactly as shown then take a screenshot:
A20400000000
A20500000000
A2060000031F

A20B726F7573

Do i scane the chip first ?
No, copy and paste it in press send then scan and hold the phone still
Yes! Now scan it outside of the app
Yesss it works !!! 
and do i have to redo this if i rewrite to it ?
No! It should be fine to use it with nfc tools now.
Okay thank you verry mutch !!! Thanks for al the help !
