Gardai are warning consumers to be wary of fake money in circulation around the country.
More than 700 incidents of counterfeit currency have been reported between January and October.
That is an increase from 130 reports in the same period last year.
Gardai say it is easy to check if a euro note is genuine. Cash handlers and member of the public should feel, look, tilt and check the note.
The note is made out of cotton and should feel crisp and firm.
Hold the note against the light and look for the watermark and the numeral value.
When you tilt the note you will see a hologram which will also show the value of the note.
Check the signature of the President of the European Central Bank.
Gardai are asking business owners and the public to be on the lookout and hand in any notes they feel may not be genuine.
