RFID UNIQUE Card Duplication: How to Copy Data to Blank Card & Necessary Devices

Question

Hello, I have a question, how to copy data from RFID card to blank card? What device is it made of? Can you do that at all? Regards

Depends on the type of card. The most popular UNIQE 125 kHz RFIDs are not saved and their unique identifier is given during production.
For other types, you need a reader-programmer suitable for the type and, of course, the appropriate software. The card systems are not compatible with each other, especially when it comes to writing (and not all of them are writable).
That's why you need to know what these cards are.

You will not copy the card yourself. I once read that someone succeeded, but it probably requires a lot of knowledge and equipment. The basic feature of these cards is the unique number. Each card sends a 64-bit data frame (synchronization preamble, frame start marker, card data, i.e. its unique number written on five bytes, CRC8 checksum, positive or negative acknowledgment and frame end marker.

I refresh the topic, because RFID copying in std UNIQUE EM4100 is already possible and I would even say that it is common.

He has such a device in the form of a portable reader that fits in the palm of your hand, powered by 2xAAA, the time of copying the RFID card is less than 10 seconds.

Copying is very easy. I present instructions on how to do it, and we will need: EMC-4 card (Q5) PRTxxEM Roger reader Free download of RARC from roger.pl

and this reader is what exactly?

I just think, is it good that this information saw the light of day, although it is not a secret, but on the other hand it may be good, because at least installers and users of these cards will be aware that copying unique cards is a trivial matter - and thus dangerous. As for the question about the reader, "xx" stands for any model from the EM series.

Here my colleagues showed a solution with unique almost contact cloning, and experts are able to clone from a distance of 3 m Unique readers are great for restricting access to ... a toilet

I am not a specialist, so I have a question. There are transponders on the ink and solvent bottles for industrial printers. How can you identify what type of transponder it is and possibly how it could be used? Maybe they will be suitable for opening the gate after installing the appropriate reader?

But what will it do if we only read the card number and its expiry date in this way? What about the one-time CVC key? Is he also read? I am asking because if it is really possible to read this key, then I go for the scissors and cut the antenna in the card

dariusz.bembenek · Answer

I might be wrong, but in the case of UNIQUE 125 kHz cards (the ones with access to the toilet) something like a CVC key probably does not exist. Payment cards with tech. PayPass is a slightly higher driving school. The CVC is already there for sure.

The Unique standard card has a serial number stored in it. It cannot be copied and recorded to another card.
There are personalization readers that encode cards so that they can be assigned to specific employees in the company.

It is true that the Unique standard is obsolete and is unlikely to be used in access control systems. However, they are successfully used in time recording systems. The employee has 1 card assigned to his account and is not able to have two.
This is enough for the needs of the RCP.

b3ck · Answer

Read my post a little higher and you will notice that it is possible.

djdamsza · Answer

Unique standard cards have a permanently saved serial number. It can be read, but it is not possible to change the card number. Unique is not a writable card. I know that there are many professionals on this forum and I will probably throw a glove on many people, but I stick to mine. Nothing can be written to the Unique card.

However, you can make a layout imitating a card from the read number. However, this is not the second card.

dariusz.bembenek · Answer

Friend above. Perhaps you understand the same thing just a little differently.
Sure, it is not generally possible to modify an already existing card number in the card. Here, no one says to put such a card on the reader and molest it to such an extent that she wants to change the number ...

We are talking about cards (an example card symbol is given above), which do not have an assigned number (this part of the memory is "free") and it is possible to "upload" any number that was previously read from a "normal" unique card.

The physical number of the card can be copied and uploaded to a writable Unique card or easily emulated using the uP, antenna and transistor key. I did such tests and it came out without any problems. There are several such designs on the electrode. And here you are wrong. Standard Unique is doing very well and many companies are using it or are going to introduce it. I am not talking only about small companies, but also about large Western concerns. The reason is not ignorance about the possibility of copying cards, but financial reasons. Unique cards and readers are much cheaper than Mifare.

easypl12 · Answer

The price of the mifare card is not much higher (max 15%) than the price of the unique 125khz card.
The reason for the popularity of unique systems is the multitude of solutions to support them and the simplicity of installation and configuration.
Mifare cards should be encoded before use, if done wrong then mifare based solution will be easier to crack / work around than unique as mifare writers are much more common.
