Pine Labs, a leading merchant commerce platform, on Wednesday announced the launch of Paper PoS (point of sale) for its merchants, which can be used to accept Unified Payments Interface (UPI) and Bharat QR payments through a merged static QR at the point of sale. Merchants can use Paper PoS to accept payments across different kinds of UPI and Bharat QR payments, including Amazon Pay, Google Pay, PayZapp, PhonePe and YONO. Using countertop POS machines, merchants can print a customer charge slip.
