MIWA Hotel Key Card Compatible

125 kHz LF

A compatible replacement for MIWA Lock Co. MIWA (PR / LA / ALV2) — a dual-frequency 125 kHz + 13.56 MHz credential, encoded by specification to read identically on your existing readers. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible MIWA (PR / LA / ALV2) works

The MIWA (PR / LA / ALV2) is a dual-frequency credential operating on both 125 kHz LF and 13.56 MHz HF, so the compatible part must carry the correct data on whichever band your readers use. Its data structure is MIWA Japanese hotel-lock encoding - PR on plaintext EM4100 LF; LA/ALV2 on a 13.56 MHz smart card; LD dual-frequency LEGIC/iCLASS. 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.

We build the compatible MIWA (PR / LA / ALV2) by encoding the matching data structure onto a programmable EM4100 / 4200 chip. Once written, the credential presents the same bits, the same facility code, and the same card number your reader already accepts. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered for the exact format your system expects.

To order, tell us the part number or format printed on your existing MIWA 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.

MIWA (PR / LA / ALV2) — common questions

Is this a genuine MIWA Lock Co. card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the MIWA (PR / LA / ALV2) so it reads identically on your existing readers, but it is not an MIWA Lock Co.-branded product. Security ID Systems is independent and not affiliated with MIWA Lock Co.; your access-control panel accepts the credential exactly the same way.

What chip is the compatible MIWA (PR / LA / ALV2) encoded on?

It is encoded on a EM4100 / 4200 programmable chip. That platform carries the original 125 kHz LF data structure precisely, so the credential presents the same information your readers already accept.

What frequency and format is the MIWA (PR / LA / ALV2)?

It operates on 125 kHz LF, using miwa japanese hotel-lock encoding - pr on plaintext em4100 lf; la/alv2 on a 13.56 mhz smart card; ld dual-frequency legic/iclass. 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 is the MIWA Lock Co. format hard to find?

The MIWA Lock Co. format is one of the specialist, proprietary credentials that many card vendors don't offer. Security ID Systems focuses on exactly these specialist and legacy formats, encoding a compatible credential to the exact specification your readers already accept.
