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.
