PayU India CEO Anirban Mukherjee has backed a simple pricing model for UPI charges. This and more in today's ETtech Top 5.Also in the letter:■ TCS, HCLTech security scare■ Slice turns profitable■ AI funding race heats upUPI fee should vary by merchant size and sector: PayU India CEOAnirban Mukherjee, CEO, PayU IndiaAny merchant discount rate (MDR) on Unified Payments Interface (UPI) should be simple and linked to merchant size and industry, PayU India CEO Anirban Mukherjee told us.More on this: Mukherjee said the fee should be the same for online and physical merchants, as their costs broadly balance out. Physical merchants involve distribution expenses, while online businesses spend more on merchant verification and risk management.He said MDR could help fund payment infrastructure, cybersecurity and fraud management.“If UPI MDR happens, I expect banks to come back very strongly into investing more in the digitisation of payments,” he said at PayU India's leadership roundtable.Tell me more: UPI makes up 52% of PayU India's transaction volume and a third of its payment value. Mukherjee said it was too early to assess the revenue impact of MDR because existing contracts would need to be considered.Background: Parliament on Monday passed legislation allowing the Centre to change the zero-MDR framework. Finance Minister Nirmala Sitharaman said consumers and most low-value merchant payments would remain free.Any MDR would be nominal and apply above a prescribed threshold, with its rate and coverage yet to be decided.Festive rush: Quick commerce firms to hire 35-40% more temp workers, tech-savvy talentQuick commerce firms are expected to hire 35-40% more temporary workers this festive season as demand for instant delivery grows, according to staffing experts.What's happening?HR firms expect strong demand for workers skilled in warehouse management systems, automated pick-and-pack operations, inventory reconciliation, RFID/barcode scanning, and artificial intelligence (AI)-based systems.Around 100,000 temporary jobs could be created during the festive season, which starts later this month.

This year, it is around 30% of the total seasonal flexi workforce demand,” said Yeshab Giri, chief commercial officer, Operational Talent Solutions at Randstad India.“Unlike previous years where hiring was concentrated in last-mile logistics, this year's surge reflects a more strategic, hyper-localised deployment,” Giri added.Also Read: ETtech Explainer: Can premium beauty, quick commerce drive Nykaa's next phase of growth?TCS says it received alerts alleging exposure of some employee dataTata Consultancy Services (TCS) on Monday said some employee data may have been exposed, but there was no evidence of customer data or systems being affected.More on this: TCS said it received “threat-intelligence alerts” about the possible exposure of employee details.It said the data appeared to be more than four years old and limited to basic employee information. The alleged breach reportedly involved password spraying and multifactor authentication fatigue.Meanwhile: The disclosure came as HCL Technologies (HCLTech) responded to media reports that a hacker group had claimed access to its employee data.In a stock exchange filing, HCLTech said its initial investigation suggested the data “may be limited and dated to a few years back”, adding that there was no evidence of a systems breach or any impact on client engagements.What else?
