How the compatible CISA CT6 (1K contactless smart card, AERO/SMART) works
The CISA CT6 (1K contactless smart card, AERO/SMART) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is 1K contactless smart card, sector-key based. When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.
As a programmable blank, the CISA CT6 (1K contactless smart card, AERO/SMART) is the raw material the rest of the catalogue is built on. We supply it factory-fresh and rewritable on the 1K contactless smart card platform, so you — or we — can encode it to emulate the proximity format your readers expect. It is the backbone of every 125 kHz compatible credential we ship.
To order, tell us the part number or format printed on your existing CISA card, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.
