Many times I see that my metal card doesn't tap successfully. Multiple attempts are needed. Is it a known issue?

It has to do with the construction of the card. In case of plastic cards, the nfc coil (as shown in attached image of Jupiter Edge CC), is overmoulded by plastic. Plastic of such nominal thickness is invisible to the electromagnetic NFC waves used to interact with the chip.Plastic vs. Metal @plastikman

However, in case of metal cards a metal card of certain thickness is milled and a slot is made. This slot is of smaller size and accommodates a small coil compared to the plastic cards. This reduces the range and sensitivity of the nfc. The chip is placed in the milled slot and powder coated to his it but the range is reduced due to the shielding effect of metal.
That's why RFID blocking wallets have metal inserts to prevent anyone from accessing one's card via nfc.

Yep I use my phone, but many times, cashiers get confused whether I am going to use UPI when I ask for CC machine but take out my phoneuse any nfc enabled device shouldnt be a problem
Please don't do that. Flaunt Infinia.Yep I use my phone, but many times, cashiers get confused whether I am going to use UPI when I ask for CC machine but take out my phone
