You will see how you will be able to save your office, sports, home whatever RFID keys you have and we'll take a glimpse at what Flipper can read from a bank card. Here we will compare these two types of tags, take a look at the main protocols and learn to work with them using Flipper Zero - we will read, emulate, save and clone them. These tags are commonly used in contactless bank cards, to pay for public transport, and in high-security access control systems. They support encryption, authentication, and cryptography. High-Frequency tags (13.56 MHz) - have a lower effective range when compared with the low-frequency ones but have more complex protocols.Despite being insecure and dumb, they are still used in primitive access control systems: in building intercoms, offices, sports facilities, museums. Low-Frequency tags (125 kHz) - work at a higher range.The two main RFID tag types are high frequency and low frequency. It is quite common and you may see it in a lot of places: intercoms, bank cards, public transport passes, office passes, they are used to track domestic animals, for toll collection, etc. Now it’s time to open the cartridge and perform the difficult stuff – winding.RFID is a contactless radio-tag technology. The printer now should show 350g/350g again.

To verify, load the cartridge into the printer. You want to write, select Sector 2 only and tap on OK. Select the radio button Write Dump (Clone), select the dump file Tap on the diskette symbol to save your changes to the dump file.

Calculate theĬRC8_DVB_S2 from these three bytes and put it in the position 15. When done, there is a CRC byte at the end of this line. Sector: 2 shows you the actual value of your filament remaining in the cartridge. It’s a little bit heavy to see I will take my example: The 5th, 6th and 7th byte value starting at 0 position is the Type, colour, the length ofįilament initial filled in and some more. Sector: 1 shows you the fix values for your filament in the cartridge. Take a second READ TAG, but now select your key file you just created. The file will be opened to insert the calculated key. The key is a 6-byte expression which has to been built with the CRC value in the step before and Now you have to calculate the key you need to read and write data from and to the chip.įor this take an online CRC calculator like sunshine or another one else.

You will get the four-byte serial number of the chip if select TOOLS then Display Tag Info The chip located on the backside of the cartridge (round Zortrax label). With your smartphone which should be able to talk to mifare classic NFC chips take a first read from How-to refill the model or support cartridge suitable for Zortrax Inventure

It’s a pity I cannot attach a pdf so I have to paste all text: If you have an empty cartridge, try it to alter the content of the NFC to initial value. If your smartphone is not, there are NFC reader which can do the job as well. If you own a smartphone which is able to talk to mifare classic chips you are on the best way to refill your cartridges if you want to. You will find a lot of information about in the internet. The NFC chip is a Mifare classic 1K chip which is often used and easy to handle. The printer reads and alter it, eg if it adjust the value of the remaining material after print. Here all informations about the material within the cartridge is stored. The Inventure printer uses a NFC chip located on the back side of the cartridge. As I have had problems with a cartridge running out of material earlier than expected and when searching this forum for others having the same problem to get help I discovered some questions like: Isn’t it possible to refill the cartridge? Interested? Let’s have a look.
