Mobile payments and wallet company Paytm on Thursday discontinued its app-based point-of-sale feature for merchants one day after its launch on data security concerns. The feature, named App POS, allowed a shopkeeper’s smartphone to act a as a point-of-sale machine by accepting debit and credit cards from customers, Mint reported. It was aimed at people who possessed the cards, but not necessarily a smartphone.

In a statement on its official blog, the company said it had undertaken “several discussions with stakeholders” on how to make the feature more secure. “Based on some suggestions from the industry, we have decided to add additional certifications and features before making it available to merchants,” the statement said. The feature will be relaunched “as soon as we have updated the product,” it added.

However, the company’s rivals and industry bodies had raised concerns about customer safety, as the feature involved adding card details on the merchant’s phone, The Economic Times reported. An official from a multinational financial services company told the daily that there was a risk of customer data being compromised. “There are screen-recording apps that can compromise the customer’s security,” the official told the newspaper.

Paytm has claimed to have crossed its $5-billion (Rs 33,000 crore) target for Gross Merchandise Value of sales four months ahead of schedule. GMV is is the total worth of goods sold through a digital platform. The company attributes this success to the Centre’s demonetisation of Rs 500 and Rs 1,000 currency notes, after which its daily transactions shot up to seven million, worth about Rs 120 crore.

The online payment company has also served more than 45 million users and has had more than five million new users join the platform following the discontinuation of the high-value notes. Currently, the firm has more than 150 million users.
