Keri’s NXT-C Standard Light Proximity Card provides maximum read range performance in a package 
considerably thinner than other “clamshell” proximity cards. It can be easily carried in a wallet or purse or worn 
on the clothing with a clip or necklace. These cards are extremely durable and convenient. The are manufactured 
with a vertical hanging slot punch, and they come with a lifetime warranty.
Keri’s NXT-I & NXT-S Multi Technology Cards allow the user to combine several identification technologies in 
a single credit card thin credential. The cards can be ordered with or without a high coercivity magnetic stripe, 
which is useful if there are other types of systems in use that are mag stripe-based, such as cafeteria vending. 
They are also useful for customers who may have a proximity-based access control system at one site and a mag 
stripe-based system at other locations, allowing the user to carry a single card. One of the most popular features 
of the Multi Technology Cards is that they can accept a direct print video image, typically a photograph, bar code, 
and other user graphics, from most industry dye sublimation printers, to create a custom access credential.
Keri’s NXT-K Proximity Key Ring Tag provides user convenience in a small, ergonomic, and extremely durable 
package. The tag is equipped with a brass eyelet for attachment to a key ring that ensures the neck of the tag will 
not break during the life of the system. Key tags are especially convenient for building entrances where the user 
still has their car keys in hand. If the system has many interior doors that are secured with a Keri access control 
system, users often attach the tag to a necklace for easy carrying, especially if the clothing does not have pockets.
All three Keri Proximity Credentials can be used interchangeably on the same system without worry about ID 
code dupliation or format matching. Also, for security purposes, all NXT credentials use 128 bit encryption 
between card and reader.
