ADASA has partnered with Metalcraft to encode specialty RFID tags. Without an ADASA encoder, there are few other options for field encoding RFID tags. If you know what numbers you need programmed into the tags at the time that are run on the manufacturing press, then none of this applies. However, this is seldom the case. Most often you really need to program the tag when you are standing in front of the asset that you want to tag and track. This calls for a special version of the ADASA cartridge family to dispense metal-mount or windshield tags. Metalcraft tags are for tough specialty jobs like asset tagging of metal objects and tagging automobiles.
 Metalcraft asset tags are used to tag assets that contain metal components such as computers, server racks, and other valuable equipment. The physicis of electromagnetic radiation is such that surrounding metal affects the RFID tag antenna, causing it to detune. Detuning results in poor read or write performance. Metalcraft overcomes this by using a layer of specially selected foam as an offset from the metal surface. The result is that valuable components can be tagged and tracked.
 Metalcraft asset tags are also used to track carts, office furniture, manufacturing equipment, tools, parts, and even 55 gallon steel drums!
The key is to have a reliable means of encoding the tags. Unless you know in advance what the numbers are that are to be encoded into the tag, you will need to have a reliable way of writing the correct information into each tag one at a time in the field. Because UHF waves are propagative, they tend to travel long distances. This is what makes them great for asset tracking because they can be read from distances of 10 feet or more with the right reader. However, being a propagative wave works against your efforts to write data into one selected tag. Unless you are very careful to minimize the electric field, while maintaining a small localized magnetic field, you will end up writing to more than one tag in the surrounding area. This will result in complete chaos for your asset tracking application.
ADASA has successfully tamed the wild UHF waves to control the process of encoding UHF tags. We are the world's leader in on-pitch tag encoding - in otherwords we can encode your UHF tags with very high spatial precision.
 Automobile windshields require special tags. Windshield tags must withstand high UV light exposure levels for extended periods of time. Windshield tags also require adhesive on the front of the tag such that it can be read through the automobile glass.
