In some
applications - size will matter.
For these, we use one of the world's smallest passive read/write
chips.
|
Tag & Trace Technology Partners, Hitachi Maxell, have developed
one of the world's smallest RFID chips using Coil-on-Chip technology.
The precision antenna coil is mounted on a
2.5mm square chip developed using Maxell's original Electro Fine Forming technology.
By placing the antenna coil on the chip surface, Maxell created a small-profile, highly reliable, and low-cost RFID chip that can be attached to, or embedded into various
products.
The Coil on Chip is a
Read/Write device with 128 Byte Total Memory which can be written to or recovered using various reader
methods. Used in conjunction with interface software the amount of information
recoverable from the chip can be vast. This memory can be custom
configured - typically, to hold
product service history, maintenance, or audit information. For custom
solutions please contact us with your application.
Precision antenna coil is mounted on the
chip's surface
By using Maxell's original Electro Fine Forming technology, uniform-thickness precision antenna coils are directly mounted onto the surface of silicon wafers. When compared to conventional
contact less chips having external antenna coils, the Coil-on-Chip does not suffer from
contact deterioration or mechanical stress because there
are no
soldered connections between the antenna coil and the chip.
Reader/Writer modules
Stand-alone read/write
is possible with a compact battery powered Handy Reader.
Communication for integrated systems is via a docking station and Maxell's exclusive
LSI chip set allows compact R/W capability to be easily incorporated
into OEM equipment.
When used in conjunction with customisable interface/encryption
software, available memory space can be maximised to satisfy most
applications.

reader and token reader. Right: A handheld Read/Write unit.
Booster coils
The use of booster coils expands the area of
communication providing increased read range. Since there is no soldered connection between
the chip and booster coil, the system is highly reliable. Booster coils are provided in various sizes and shapes, such as price tags or plastic cards, to meet individual user's needs.
