RW1990 Ibutton adopts single-wire protocol communication, and completes data reading and writing through instant touch. It not only has the ease of operation of non-contact IC cards, but also has the cheapness of contact IC cards. It is one of the most cost-effective IC cards at present.
The RW1990 Ibutton with unique 64-bit code is a full quality analog of Dallas/Maxim DS1990A-F5 iButtons. Designed for access control systems each key has a unique family code that is recorded while the key is being produced and the code cannot be overwritten.
While manufacturing such devices in the factory, the number is directly assigned directly to the production line. Each TM1990A-F5 is assigned a unique identification code consisting of numbers and letters. The approximate number of combinations – 4 billion. Therefore the chance to guess the key from the entrance is practically zero. The key contains a number. It can not be charged or magnetized. But it can be stored in the memory controller, which controls the door to the entrance or office.
The RW2000 Ibutton Key Card is a one-time programmable 1-Wire access credential built for deployments where a credential must be provably single-assignment at the hardware level. Every unit ships blank and accepts a single high-voltage write pulse via TM Pro programmer — on-chip fuse physically blows after the first programming cycle, permanently locking the UID. No software flag. No reset path. No field tool — Flipper Zero, Arduino, Proxmark3, or standard TM handheld — can overwrite it. Same 16 mm SUS304 steel housing, same 15 mm wide ABS handle (55 mm total), same seven stock colours as the TM1990A-F5 and RW1990, but the silicon guarantees zero re-assignment risk for the life of the credential. Deployed in government facilities, national railway signal-post access, and Cyfral/Metakom intercom networks across Eastern Europe. ISO 9001:2015 factory, CE marked. 2,000,000+ monthly capacity across five production lines. Free evaluation kit with TM Pro programmer ships within 3 business days.

The RW1990 RFID Ibutton is a field-programmable 1-Wire access credential built for rotating deployments — student housing, co-working spaces, locksmith universal stock, and any site where credentials change hands monthly. Each unit ships blank and accepts a write command through a standard TM handheld programmer: encode a UID, lock it, deploy. When the tenant moves out, re-write a new UID onto the same hardware and hand it to the next person. Same 16 mm stainless steel housing, same 15 mm wide ABS handle (55 mm total), same 1-Wire contact bus as the read-only version — but with reusable hardware that eliminates per-tenant replacement cost. 2,000,000+ monthly capacity, 340+ B2B accounts, seven stock colours, custom Pantone available. Free 10-unit evaluation kit with programmer ships within 3 business days.
The TM1990A-F5 iButton keys tag is a read-only 1-Wire access credential with a factory-burned 64-bit UID that cannot be overwritten or cloned. Each unit combines a 16.25 mm F5 stainless steel MicroCan with a 40 mm virgin ABS paddle handle and reads in under 5 ms at 142 kbps overdrive on any compatible 1-Wire probe reader. Works with Iron Logic, Bolid, ZKTeco, and Teltonika terminals. Ideal for permanent single-issue credentials in apartment access, fleet driver ID, and employee attendance. −40°C to +75°C operating range. IP64 splash-proof. 10+ year service life.
