xM1 Plus

We are holding sale of the xM1+ to investigate a chip supply issue.

The xM1 Plus is a “Classic S50 1k” chip emulator with writable sector 0 (including UID) by way of a “Chinese Magic Backdoor” feature. This allows you to overwrite all pages in every sector, including Sector 0, regardless of A/B key values or access bit settings.

WARNING This kit definitely contains dangerous things. While the xM1+ transponder device has undergone several quality checks during manufacture and has been put through a battery of tests with various private labs, it has not been tested or certified by any government regulatory agency for implantation or use inside the human body. Use of this device is strictly at your own risk.

The xM1+ kit contains the xM1+ tag and all the sterile procedure materials required to perform installation. The xM1 tag is made with a 13.56MHz ISO14443-A compliant “Classic 1k” emulator chip, which is encased in a biologically safe 3x13mm cylindrical bioglass tube. The bioglass cylinder is laser sealed and the finished xM1+ tag is tested for function before loading into the injector assembly, and the whole injector assembly with xM1+ tag inside is EO gas sterilized.

What’s so great about the xM1+ ?

Basically, for many years the MF1ICS50 1k chip was used for all kinds of applications as a “secure chip” for everything from access control to stored value cards, and used for making localized payments within closed systems like public transit and laundry services… but it’s security mechanism called “crypto1” is a simple, proprietary encryption mechanism that hardly has anything to do with modern cryptography. It has been broken for many years now, but the sheer number of systems out there that still use it means the S50 will continue to be used by legacy systems around the world for years to come. So now, you can crack the security on those cards and clone their content (including the UID “serial number”) to your xM1+!

Complementary Products

xLED Field Detector
xLED Field Detector
The small cylindrical shape of x-series transponders can sometimes cause difficulty getting a reliable read with certain readers. The xLED is a diagnostic tool for testing different reader antennas to find the best position and orientation for your xM1+. The xLED can show you the best way to present your xM1+ to a particular reader by lighting up when the field coupling is strong.
EMLA Anesthetic Patch
Anesthetic Patch
This anesthetic topical patch completely numbs an area of skin approximately 1 inch in diameter and allows pain free x-series installation.
PN532 NFC Reader
PN532 NFC Reader
The PN532 reader module is an Arduino compatible RFID and NFC reader/writer module you can use to build custom projects and solutions with.
NFC Shield
PN532 NFC Reader
Adafruit has taken their popular PN532 breakout board and turned it into a shield – the perfect tool for any 13.56MHz RFID or NFC Arduino application.
Dangerous KBR1
The Dangerous KBR1 is an ISO14443A RFID/NFC keyboard wedge reader that will act like a keyboard and “type out” any tag UIDs it scans, as if someone typed the ID on a keyboard. Great for quickly reading UIDs from ISO14443A tags, making spreadsheets, and can even be used for quick and easy computer login!
