IB981
Passive Cotag keyring tag
The IB981 is a factory-encoded passive tag that does not include a bat-
tery. It can be used in combination with any Cotag reader. When it is
used with a Cotag hands-free reader‚ the reading range is approximate-
ly 29 cm. With Cotag proximity readers‚ the reading range with the
IB981 varies between 2 and 9 cm.
One of the major advantages of Cotag technology is that active and
passive cards can be mixed in the same system to provide ultimate con-
venience and cost-efficiency.
Note: The card number is printed on the back of the card.
