On 12 September 19, the Swiss National Bank issued the new 100 Fr Note. This will require an update of the existing devices with the cashflow readers we sell, 
if you also want to accept this note. The update is now available for the models Cashcode MSM, MSMv. You can order sticks for a convenient update on site 
or send existing ones for update.
