RFID Card Reader, UHF USB Desktop Reader Writer 902～928MHz Frequency, 50cm Contactless Proximity Sensor Built-in Buzzer, Compatible with ISO18000-6C, ISO18000-6B

It says software adjustable but there’s no software included

It does not write at all and there is no software. It simply reads the tag and acts as a keyboard and types it out. For example, if the tag was just "A," it would simply press "A" as if it were a keyboard.

No tiene información de absolutamente nada.

Works as a USB HID device so it will work with Linux. Worked great for my application.

First of all, I didn’t expect this thing to do exactly what I wanted it to. However, I did expect it to be an actual UHF RFID reader. What this thin actually is , is a keyboard emulator that reads the tags, and turns them into keystrokes and puts them on whatever window is active. I am going to be returning this, but only because it doesn’t do what I need it to.

I use these to checkout products on my POS system instead of using barcodes and they work quite well at a very economical price. I would however like some software so that I could calibrate the read range, for my purposes I don't want them to be so sensitive to read items on the shelf, I only want them to read up close. I wish the supplier could provide some software to be able to adjust distance of reader.
