Make a copy of an RFID tag?

Question

RFID

Hello dear.

Given:
— Doors with label reader;
- a simple RFID tag (not a bank card);
- Google Nexus 7 with NFC support.

You need to read the tag and give it via NFC with a tablet. Try to make a copy of the label from the tablet. What software for android to use? And is it even real?
Unfortunately, I don't know what type of label I have. How can you determine what type of label?
It is unnecessary to offer to buy a reader and tags separately.

As a thank you - a plus sign in karma.

Answer 1

If the label belongs to the compatible NFC standard, then you can try to make a copy on the tablet (there are also restrictions there).
If not, then a copy using a tablet cannot be made.
It is easy to check the label standard - you need to try to consider it a tablet, if it was not considered, then it means it is incompatible.

Answer 2

Tags are different. There are "stupid" - EM-Marine, there are "smart" - Mifare and company. What do you have? EM-Marine can be copied, most likely nothing will work with the Mayfair (depending on the model and the cryptography built into it).

Answer 3

Depends on the type of label, you can read or ask the author here .

Answer 4

If you have solved this issue, could you share it?

Answer 5

I also got interested in the topic. I have a VIZIT Safe Home intercom key fob. I want to transfer his label to a phone with NFC. On androyd, I have not yet found a program that allows you to do this. I also read that the technologies are slightly different, RFID transmits data further than the NFC ...
Where to dig further?
here is such an intercom in my entrance:
