Hmmm.. thanks, auto topup is nice. It seems NPCI increased the lite limit to 5000 but GPay and BHIM both show 2000 still. Will wait until they update it because 2000 is too low.
I had seen it first on the Tata Neu iOS app a month or two ago and it opens the interface to complete the payment. However, haven't had an opportunity to try it yet.
I suppose Apple is allowing the NFC chip to read content which in this case is the UPI ID stored in the NFC tag. However, actual payment over NFC is yet to be made available.
