With an inbuilt battery the D50+ can count 250 bank notes a minute, without even needing to be near a plug socket, making it perfect for markets or festivals. By using 7 different technologies the counter checks every note to ensure it is authentic and the European Central Bank found that it could find a counterfeit note 100% of the time. Not counting currency? Simply switch off the counterfeit detectors and now you can count coupons, vouchers or tickets. Compatible with the new £5 and £10 note.
