Blank Programmable Cards

CISA CT6 card compatible

13.56 MHz HF S-tier format No compatible sold online elsewhere

A factory-fresh, rewritable CISA CT6 (AERO / SMART, Mifare Classic 1K) — the programmable blank our compatible 13.56 MHz smart cards are encoded onto, supplied loose or pre-encoded in bulk. One of the specialist formats few suppliers offer — order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible CISA CT6 (AERO / SMART, Mifare Classic 1K) works

The CISA CT6 (AERO / SMART, Mifare Classic 1K) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is MIFARE Classic 1K sector-key based; CISA branding on Sectors 0-4, Sectors 5-15 factory default. 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 (AERO / SMART, Mifare Classic 1K) is the raw material the rest of the catalogue is built on. We supply it factory-fresh and rewritable on the Genuine NXP MIFARE Classic 1K 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.

The CISA format sits among the specialist proximity credentials most card vendors never tooled up to produce — which is why the only other source is usually the original manufacturer, at a steep premium. Supporting these hard-to-find formats is exactly what Security ID Systems specialises in. Tell us the format printed on your card, or send a sample for us to read, and we confirm compatibility before you order.

CISA CT6 (AERO / SMART, Mifare Classic 1K) — common questions

Is this a genuine CISA card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the CISA CT6 (AERO / SMART, Mifare Classic 1K) so it reads identically on your existing readers, but it is not an CISA-branded product. Security ID Systems is independent and not affiliated with CISA; your access-control panel accepts the credential exactly the same way.

What chip is the compatible CISA CT6 (AERO / SMART, Mifare Classic 1K) encoded on?

It is encoded on a Genuine NXP MIFARE Classic 1K programmable chip. That platform reproduces the original 13.56 MHz HF data structure precisely, so the credential presents the same information your readers already accept.

What frequency and format is the CISA CT6 (AERO / SMART, Mifare Classic 1K)?

It operates on 13.56 MHz HF, using mifare classic 1k sector-key based; cisa branding on sectors 0-4, sectors 5-15 factory default. Matching that exact frequency and data structure is what makes a compatible credential work — a card on the wrong band or bit length simply will not read.

Why can't I find this compatible card anywhere else?

The CISA format is one of the specialist, proprietary credentials most card vendors never tooled up to produce, leaving the original manufacturer as the only source. Security ID Systems specialises in exactly these hard-to-find formats, which is why we can supply a compatible credential when no one else lists one.
