wafer, COB, PDIP or SOIC package options
Applications
Item Level Tagging:
To read and write multiple
items in long read range environment.
Anti-Counterfeit:
The device has a unique
feature to distinguish between paid, unpaid or
returned merchandise.
Inventory Management:
Tag’s data can be read
or updated (written) in multiple tags and long
range environment. Its memory (32 blocks, 1 Kbit,
each block = 32 bits) is well organized for the
inventory management applications.
Product Identification
s
Airline Baggage Tracking
Book Store and Library Book ID
Low Cost Animal Ear Tags:
The device’s long
range reading performance combined with 1 Kbit
of memory is suitable for animal tagging applica-
tions. Tag cost can be cheaper and read range is
much longer than existing 125 kHz conventional
animal ear tags.
Toys and Gaming Tools:
Device’s anti-collision
feature for reading and writing allows to make
intelligent interactive toys and gaming tools.
Access Control and Time Attendance Cards:
Device’s long range performance allows to make
long range access control, parking lot entry, and
time attendance cards.
Inexpensive finished tags and readers are available
from Microchip’s worldwide OEM partners. Please
