HF Desktop Reader Writer

What the IDTS-RWS9 HF desktop reader writer does

The IDTS-RWS9 belongs on the desk where cards are issued. Connect it to a PC over USB, place a 13.56 MHz HF card or tag on it, and your software can read the card's ID or write data to it. The card has to be within 0–5 cm, so the reader only talks to the card in front of the operator, which is exactly what you want when encoding cards one at a time.

Because it is supplied as a reader writer, it comes with free demo software for trying it out and the SDK for the read/write model for building it into your own application.

Typical jobs at the issuing desk

• Employee and student ID cards: enrol each new card against a person in your attendance or access software before handing it over.
• Membership and loyalty cards: write a member number or other data to the card at the counter.
• Checks before a rollout: confirm that a sample batch of HF cards, labels or tags reads and writes correctly before you order in volume.

How it fits into your software

The reader supports answer, active and trigger operating modes, so it can either wait for commands from the host application or report cards on its own. The baud rate is selectable from 9600 to 115200 bps. A buzzer and LED confirm each read, so operators can work through a stack of cards without watching the screen. Power comes over the same USB cable, so there is no adapter on the desk.

The 123 × 95 × 27 mm housing is IP40 rated: it is made for indoor desks and counters, not for door frames or outdoor posts.

Choosing between our HF desk readers

The HRD20 desktop reader is a slimmer unit with a longer 5–10 cm tap distance, suited to reading card numbers at a reception desk. The RWS9, sold as a reader writer, is the one to pick for an issuing desk where cards are encoded one at a time.
