  • Product Description

    The xEMi injector assembly contains a 2x12mm 125kHz ATA5577 based xEM tag, pre-programmed as an EM4200 compatible tag. The xEM tag is encased in biologically safe Schott 8625 bioglass and pre-loaded into a sterile injection assembly. Many low cost OEM and commercial 125khz RFID readers are capable of reading this tag.

    Kit Equipment

    – 1x sterile injection assembly, preloaded with an xEM 2x12mm tag
    – 1x single use ChloraPrep skin prep ampoule with cotton scrub tip
    – 2x sterile gauze pads for prep and post-injection wound care
    – 1x sterile small round adhesive bandage
    – 1x pair of non-sterile, non-latex surgical gloves

    WARNING This kit definitely contains dangerous things. The xEM transponder device has not been tested or certified by any regulatory agency for implantation or use inside the human body. Use of this device is strictly at your own risk.

    xEM Tag Details

    – ATA5577 (EM4102/EM4200 compatible) 125kHz LF 2x12mm RFID tag
    – Pre-programmed with a 40 bit unique ID
    – Encased in a 2mm by 12mm bio-compatible glass shell
    – No Parylene C or porous polypropylene “anti-migration” coating means easy removal/replacement
    – Shipped in sealed sterilization bag, sterilized in an autoclave

    Tag Testing

    Because the xEM tag comes pre-loaded inside the injection syringe, you cannot test the tag before it is ejected from the syringe. Because of this, we performed a read test on every single xEM tag before it was inserted into the injector assembly and sterilized.

    Read Range

    Passive RFID and NFC tags are magnetically coupled devices that pass power and data over a shared magnetic field. This means their effective read range depends on how well both of the antenna coils in the tag and reader couple with each other. This typically means the shape, size, and orientation of both antennas must be complimentary. Unfortunately, most reader devices, including mobile phones, typically have antennas designed with thin flexible PCB traces made into blocky rectangular shapes that lay along a flat plane. These antenna designs are great for coupling with and reading large flat label tags or card style tags and access cards, but they have a hard time coupling to the very small cylindrically shaped antenna coil inside our implantable tags. Most commercial readers and access control devices have a “sweet spot” that must be located and used each time to get consistent reads. Please do not expect your xEM tag to achieve the same read range that you normally get with a label tag or access card. For examples of this, please check out the following video posts; reading with USB device, and reading with a mobile device.
