Indala FlexPass 26-Bit Compatible Cards & Fobs
Indala FlexPass 26-bit is a 125 kHz proximity card format using PSK modulation — architecturally distinct from HID Prox — with Wiegand output supporting 255 facility codes and up to 65,535 card numbers per site.
Does American Key Cards make Indala FlexPass 26-Bit compatible cards?
Yes — American Key Cards supplies non-OEM Indala FlexPass 26-Bit compatible cards and key fobs (AKC Indala FlexPass 26-Bit Compatible Card), encoded to your facility code and card-number range and ready to use on your existing Indala readers. No hardware changes, no OEM dealer minimums, at a fraction of OEM pricing.

The Indala FlexPass 26-bit format was developed by Motorola and later acquired by HID Global, operating at 125 kHz with Phase Shift Keying (PSK) modulation that makes it physically incompatible with standard HID Prox readers despite sharing the same carrier frequency. Cards output standard 26-bit Wiegand data to the access control panel, supporting up to 255 facility codes and 65,535 card numbers per facility, and are widely deployed in legacy commercial and residential buildings equipped with Indala 603 and 610 series readers.

Can Indala FlexPass 26-Bit cards be cloned?
Yes — Indala FlexPass 26-Bit is an open format that can be reproduced from its facility code and card number. We don't copy individual cards on request, though — we manufacture new, correctly-encoded credentials for the systems you own or manage.
Cards use PSK (Phase Shift Keying) modulation — a fundamentally different air-interface protocol than HID Prox (ASK/FSK). Readers are not interchangeable with HID Prox readers. The optional FlexSecur layer adds site-specific encryption between card and reader, but base 26-bit cards without FlexSecur are reproducible from facility and card number.
Where Indala FlexPass 26-Bit is used
- Legacy commercial office buildings with Indala reader infrastructure
- Multi-tenant residential buildings with Indala 603/610 readers
- University and campus access control systems
- Parking and gate control with Indala FlexPass readers

Can Indala FlexPass Cards Be Cloned? PSK vs. FlexSecur Explained
Standard Indala 26-bit FlexPass cards can be reproduced from facility and card number data — but FlexSecur-encrypted cards cannot. Here's exactly what's possible and what a 'compatible' Indala card actually is.
Indala FlexPass 26-Bit Card Replacement Guide
Indala uses PSK modulation — incompatible with HID Prox readers at the same 125 kHz. Find compatible cards for Indala 603/610 readers and how to order.
Indala vs. HID Prox: Why They're Not Interchangeable
Indala FlexPass uses PSK modulation, HID Prox uses FSK/ASK — same 125 kHz, completely incompatible. Confirm your format before ordering replacement cards.

Indala 27-Bit (Proprietary)
Indala 27-bit is a proprietary Indala/Motorola format extending the 26-bit structure to 13-bit facility codes (0–8,191) and 14-bit card numbers (0–16,383), used in larger deployments requiring more site code capacity.

Indala ASP/FlexSecur adds site-specific encryption between card and reader at the 125 kHz PSK air interface, preventing cloning — cards and readers are paired per site and cannot be substituted with generic or aftermarket credentials.

Are Indala FlexPass cards compatible with HID Prox readers?
No. Indala uses PSK (Phase Shift Keying) modulation while HID Prox uses ASK/FSK modulation. The two systems use the same 125 kHz carrier frequency but are incompatible at the air-interface level — you need a dedicated Indala reader to read Indala cards.
What information do I need to order replacement Indala 26-bit cards?
You need your facility code (1–255) and the card number range (1–65,535). These are typically printed on your existing cards or available from the system installer. We program each card to your exact specs.
Can Indala FlexPass 26-bit cards be cloned or duplicated?
Yes — standard Indala 26-bit cards without FlexSecur encryption can be reproduced from the facility code and card number. Our compatible cards are programmed to your specified facility and card numbers and will work in place of OEM cards.
