This inexpensive and fairly simple device allows you to copy cards and key fobs in two popular (and at the same time three unpopular) formats.

The device is about the size of a small remote control. Of the 15 buttons, usually only three or four are needed: power on, read, write, and possibly select a standard.

The device is powered by two AAA batteries (when not in use, it is better to remove the batteries: in 10 months the batteries in the turned off device are completely discharged).

The device does not have a screen and it reports all events and modes in a female voice in English. Not very convenient, but that's how it is.

When turned on, it says "07ID 125 kHz" (says Zero seven ID one hundred twenty five kilohertz).

To read the most common cards and key fobs of the EM-MARINE 125 kHz standard, we lean the card or key fob against the blue picture on top of the device and press R. The device says: "ID 125 kHz read success card number is 1234567809" (the number will be the one on the card or key fob). Next, we lean a rewritable card or key fob and press W. The device says "Write success". You can record several key fobs or cards at once by leaning them and pressing W.

Usually Em Marine cards and key fobs have their number written on them. The most popular reader of such Iron Logic cards looks like this.

There are readers and a completely different type. Here, for example, in my garage the gate opens like this.

There are no problems with copying key fobs and 125 kHz cards.

The device supports five standards: 125 kHz, 250 kHz, 375 kHz, 500 kHz, 13.56 Mhz. When you press the S button after turning it on, it says "ID 250 kHz", with subsequent presses "ID 375 kHz", "ID 500 kHz", "Mifare IC Card".

I have never seen 250/375/500 kHz cards and key fobs, but Mifare 13.56 Mhz cards are used everywhere (these are access cards / key fobs, Troika cards, bank cards, and NFC).

The Mifare standard is quite complicated: cards can have not only a number, but also encryption, and their own flash memory, as in Troika, and even their own built-in crypto processor. Only the simplest Mifare cards can be copied without protection.

I tried to copy the key of such an intercom. It was read, successfully signed up, but, alas, the intercom does not see a copy - it means that encryption is used there.

Surely, there are many devices of the Mifare standard, whose cards and key fobs can be copied.

The device allows you to record cards and key fobs without reading if their number is known: press C, enter the number, and then attach a rewritable key fob or card and press W.

I bought the copier complete with three 125 kHz rewritable fobs and three 13.56 Mhz rewritable fobs. This set is worth about 900 rubles. Additional key chains of any of the two standards are sold there.
