Hotel Key Cards Compatible With MIWA
MIWA ALSOK and BeSic RFID locks common in Japanese-brand hotels.
The direct answer
Yes — American Hotel Cards supplies RFID key cards compatible with MIWA ALSOK and BeSic locks. They use 13.56 MHz MIFARE credentials on the ISO/IEC 14443-A standard, in CR80 format, custom-printed and supplied blank (or pre-encoded to your profile) for your property to program on its own MIWA system. We never copy a guest’s active card.
Overview
How MIWA reads a key card
MIWA Lock Co. is a major Japanese lock manufacturer whose hotel systems — ALSOK, BeSic and the DTRG line — are common in Japanese-brand hotels and increasingly in U.S. properties affiliated with them. The MIWA RFID locks read 13.56 MHz credentials in the MIFARE family. Cards we supply are standard CR80 RFID cards with the chip matched to your MIWA configuration.
Because MIWA’s RFID systems use MIFARE (Classic or, where configured, encrypted DESFire), the right card is the one matched to your specific setup. We supply blank cards for your own MIWA encoder to program, or pre-encoded cards to a profile you provide, plain or fully custom-printed to your brand.
The credential is written by your own MIWA management software and encoder; we provide compatible card stock. On encrypted DESFire configurations the credential cannot be cloned, so on-site encoding on your own system is the secure path — and the one we use. Because MIWA configurations vary, a sample card or your exact lock model is the fastest way for us to confirm the right inlay.

How encoding works
MIWA ALSOK / BeSic credentials are written by your own MIWA management software and encoder, not by us. We supply the blank or custom-printed card; your property programs the room, dates and access rights on-site. On DESFire configurations the credential is encrypted and cannot be cloned, so encoding on your own system is the secure path. We provide compatible stock and never copy a live guest card.
What we make for MIWA
We supply cards compatible with MIWA ALSOK, MIWA BeSic and MIWA DTRG (13.56 MHz MIFARE, encoded on your own MIWA system). Because MIWA configurations vary, send us your lock model or a sample card and we will confirm the exact chip — Classic or DESFire — before you order.
Ordering tips
- MIWA is common in Japanese-brand hotels — if your property is affiliated with one, your standards team may already specify the exact MIFARE profile; share it and we will match it precisely.

MIWA compatibility, answered
What key cards work with MIWA locks?
MIWA ALSOK and BeSic RFID locks read 13.56 MHz MIFARE credentials. American Hotel Cards supplies compatible CR80 cards — MIFARE Classic or DESFire to match your configuration — custom-printed and shipped blank for your MIWA encoder, or pre-encoded to your profile.
Can you copy or duplicate our existing MIWA card?
No. We supply compatible blank or custom-printed cards that your own MIWA system encodes with each guest’s details. On encrypted DESFire setups the credential cannot be cloned. We never copy a live guest card; you keep control of access.
What chip and technology does MIWA use?
MIWA ALSOK and BeSic RFID locks operate at 13.56 MHz on ISO/IEC 14443-A using MIFARE credentials (Classic or encrypted DESFire). We match the card to your specific configuration — and because MIWA setups vary, a sample card confirms it fastest.
Can you print our branding on MIWA-compatible cards?
Yes. MIWA-compatible cards are fully custom — full-bleed CMYK, Pantone matching, metallic foil and spot UV — all surface finishes that do not affect how the lock reads the card.
What is the minimum order for MIWA-compatible cards?
Minimums start at 500 cards, with most custom orders shipping in roughly 2–3 weeks after artwork approval. Plain stock and reorders are typically faster — share your timeline and we will plan around it.
Will these work with MIWA BeSic specifically?
Yes — BeSic is a 13.56 MHz MIFARE platform, so our compatible CR80 cards encode on your own MIWA system exactly as designed. Confirm whether your BeSic doors are configured for MIFARE Classic or DESFire and we will supply the matching inlay.
