The Topaz Model T-L766 is a complete and versatile pen-input system for the capture of signatures used in countertop, desktop, or portable applications.

The advantage of a Topaz LCD tablet is the ability to capture a digital signature with the ease and familiarity of ink-on-paper by use of "electronic ink" displayed under the pen tip as a user signs.

The LCD can also be used to display text and graphics from the host computer and pen-tap "hot spots" allows users to navigate between multiple screens and forms, inputting information or checking preferred options.

The large signing area and small size of the LCD 4x5 make it a great tool for capturing signatures in any environment where a large screen for graphics AR text are desired.

The active electromagnetic pen is designed for a long life of over 30-million tip activation cycles, is tethered to the tablet to prevent misplacement, and when not in use can be kept in attached storage module.

3 out of 5 eggsIt's OK.

This review is from: Topaz SignatureGem Interactive LCD Series SG LCD 4X5 HID-USB BackLit T-LBK766-BHSB-R Signature Capture Pad

Pros: Great Warranty. Small sleek design. The new machines have a brighter screen are easier to see.

Cons: I have to use this Signature pad because our purchasing system requires it. There are 2 major cons. The first is that the signature pens themselves break frequently and are nearly $50 to replace. They are cheaply made in my opinion and the tips are fragile. Expect to replace 4 pens per year with heavy use.

The second complaint is that the USB port in the back of the pad is not durable. I have had several repairs to my units over the years because of this. Granted, I move my pads frequently and if there is frequent unplugging the port will wear out.

This review is from: Topaz SignatureGem Interactive LCD Series SG LCD 4X5 HID-USB BackLit T-LBK766-BHSB-R Signature Capture Pad

Pros: Easy to setup
Much nicer having USB and has built in virtual usb to serial converter. Great color image

Cons: Here we use one image for advertising and then another image loads to sign, and it seems the images can not be very complex or the signature pads will freeze up after a few times of switching images.

No issues freezing up on less complex images with white back grounds instead of a black (color) background.

Other Thoughts: These freezing images could be our third party software, but not 100% sure yet.
