Afterpay shares dip despite sales growth

'Pay now, buy later' group Afterpay Touch says it will introduce tougher ID checks to prevent fraud.

Shares in payments platform Afterpay Touch have fallen despite the company's positive third quarter results and its vow to introduce tougher ID checks.

Afterpay says its underlying sales revenue of $530 million for the quarter is more than triple what it made a year ago and while losses linked to fraud are low, the company will introduce stronger ID verification checks.

Shares in Afterpay were down 3.2 per cent to $5.75 at 1230 AEST on Wednesday.
