Great style of number keyboard for just simple input!
Would be completely unable to self program the text that shows on the first line on the screen. Seller can program this text to say whatever, but wouldn't be able to change it after sale.Seller can also reprogram the buttons to press different keys etc, but can't reprogram by yourself.For anyone to know before buying, 'plaintext' shows the number on the second line, 'cypertext' will mask all numbers with asterisks!Otherwise, still functions as like a keyboard, with the unit I receieved, the f1/f2/f3 keys simply send 'a' 'b' 'c' as a keyboard input, works for me, can link that with my single board computer to have input! Just is NOT programmable to change the text on screen, keys will show, enter press clears second line.Wish the sellers programable version of this numpad keyboard was for sale on Amazon but it's out of stock!

Nice unit
Nice little unit, the only concern is that when you type in a number you can’t see it in the display but otherwise a great unit!!
