About us
A dedicated Touch Memory factory supplying distributors, security integrators and OEMs worldwide.
We are a dedicated manufacturer of TM cards, RFID tags and the readers around them, exporting in volume for over a decade. The core TM1990A-compatible chip is our own design — which is why we can go where trading companies cannot: custom family codes (01h → 08h or any value you specify) and even re-defined CRC rules, so your controllers accept only your keys.
Every batch is tested for ROM integrity and read reliability before packing, and we ship with the documentation your customs and customers expect.
iButton devices shipped worldwide since the technology launched — per Analog Devices, which acquired original maker Maxim Integrated in 2021 and keeps the line in production.

Inside the factory
Contact keys are a volume business, so the things that actually determine whether a shipment is good happen on the assembly floor — not in a brochure.
Buttons are sorted, pressed into fobs and tested by hand at the benches you see here. Every unit is function-tested before packing — not sampled — because a single dead key in a batch of ten thousand becomes a complaint from an installer standing at a door.
