How the compatible Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) works

The Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is SMARTair encoding; multi-format (Classic encode-friendly, AES-secured smart card / iCLASS keyed). 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.

Because the Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) is a secured smart credential, it is designed so the encryption keys stay under your control. We supply compatible blank credentials built on the matching AES-secured 13.56 MHz smart card / 13.56 MHz ISO 14443-A memory card platform, ready for your access-control system or integrator to enrol exactly as it would credentials ordered through the original vendor's channel. You get drop-in spares and bulk stock at a fraction of OEM pricing — and because your own system writes the keys, every credential inherits your site's security.

To order, tell us the part number or format printed on your existing Mul-T-Lock 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.

Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) — common questions

Is this a genuine Mul-T-Lock card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) so it reads identically on your existing readers, but it is not an Mul-T-Lock-branded product. Security ID Systems is independent and not affiliated with Mul-T-Lock; your access-control panel accepts the credential exactly the same way.

How do you supply a replacement for my secured Mul-T-Lock smart card?

The Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS) is a secured smart credential, so the encryption keys stay under your control. We supply compatible blank credentials on the matching AES-secured 13.56 MHz smart card / 13.56 MHz ISO 14443-A memory card platform that your own system or integrator enrols — exactly like ordering blanks through the original vendor's channel, at a fraction of the cost. Because your system writes the keys, the credential inherits your site's security.

What frequency and format is the Mul-T-Lock SMARTair / i-max (contactless smart card / ISO 14443-A memory card / AES-secured smart card / iCLASS)?

It operates on 13.56 MHz HF, using smartair encoding; multi-format (classic encode-friendly, aes-secured smart card / iclass keyed). 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.
