    Product Description

    The xM1 is an ISO/IEC 14443-A Mifare S50 1K RFID chipset encased in a 2x12mm cylindrical USP grade lead-free borosilicate biocompatible glass housing. The xM1 can be read and written to by many types of 13.56MHz RFID systems. While not truly an NFC compliant tag type, the xM1 does have limited NFC compatibility with certain NFC enabled Android devices such as the Samsung Nexus S, Samsung Galaxy Nexus, the Nexus 7, the HTC Amaze, etc. as well as Windows Phone powered devices such as the Nokia Lumia 920. It has 1KB memory and supports Crypto-1 encryption.

    NFC Compatibility

    WARNING: The xM1 is based on the Mifare S50, which is one of the most popular RFID chips in the world. Unfortunately, the Mifare S50 is not officially an NFC compliant tag conforming to NFC Forum tag types 1 through 4. However, many NFC enabled mobile devices that contain the NXP NFC reader IC, and some desktop NFC readers, will still read and write to the xM1. NFC enabled Android devices such as the Samsung Nexus S, Samsung Galaxy Nexus, the Nexus 7, the HTC Amaze, etc. as well as Windows Phone powered devices such as the Nokia Lumia 920 all have no problem reading/writing the xM1. Certain devices like the Google Nexus 4 phone and Nexus 10 tablet do not use the NXP NFC reader IC and can only read the xM1’s UID bits and cannot access any memory blocks for use with NFC. Check out the xNT for a fully NFC compliant glass tag option!

    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 mobile phones and reader devices have a “sweet spot” that must be located and used each time to get consistent reads. Other devices, such as the Samsung Ezon digital deadbolt lock, tend to use wire wound coil antenna loops inside, which work much more reliably with small glass tags like our x-series tags. Please do not expect your mobile device to achieve the same read range with our x-series tags that you normally get with a label tag or card. For examples of this, please check out the following video posts; reading with USB device, and reading with a mobile device.
