Money counters and counterfeit detection

A bill counter saves time at the end of every shift and catches the worst counterfeits on the way. How much it catches depends on which detection methods it has, and the letters on the box tell you.

The detection letters

  • UV (ultraviolet). Genuine US currency paper does not glow under UV light, and the security thread in a $5 and up glows a color specific to its denomination. UV catches notes printed on ordinary bleached paper and many "washed" notes.
  • MG (magnetic). Parts of US notes are printed with magnetic ink. A sensor checks for it. Catches most inkjet and laser copies.
  • IR (infrared). Checks features that appear, or disappear, under infrared light. Catches better counterfeits that pass UV and MG.
  • MT (metal thread) checks for the security thread. DD (double detection) stops two notes stuck together being counted as one. Size detection catches foreign or odd-sized notes.

No counter is a guarantee. A machine that flags a note is a prompt to check it by hand: the watermark, the security thread, the color-shifting ink on the lower right numeral of a $10 and up.

Piece counters and value counters

A piece counter counts notes. You sort the drawer by denomination first and count each stack. A value counter (mixed-denomination counter) reads each note's value with an image sensor and totals a mixed stack, so a drawer can be counted without sorting it. Value counters cost several times as much and pay for themselves where several drawers are counted every day.

What else to check

  • Batch mode stops at a set count, for strapping in 100s.
  • Hopper capacity and speed matter less than detection for most shops.
  • Currency support, if you take euros or Canadian dollars.
  • Updates. Currency designs change. A counter whose detection can be updated lasts longer.
