Visa said users enrolled in its Checkout service are more likely to complete a transaction than those with a rival service from PayPal.

The credit card firm said Checkout users are 66 per cent more likely to follow through with a purchase in their shopping cart than traditional users, compared to a 49 per cent figure with PayPal’s Express Checkout.

The figures were collected by research firm ComScore for a survey commissioned by Visa itself.

PayPal’s Anuj Nayar, senior director of platform, merchant and next-gen commerce engagement, told Reuters he had not seen the report but did point out, in addition to Express Checkout, PayPal was rolling out One Touch, which makes checking out faster.

Mobile World Live also approached PayPal for comment and will update when we get a response.

PayPal has talked up how One Touch, which was this week introduced in many Western European markets, boosts conversion rates.

One year after launching, Visa Checkout has more six million registered users. Meanwhile, One Touch, which first launched in the US a year ago, claims “millions” of users.
