Is there a tapping problem with metal cards?

[infinia_finally]

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

use any nfc enabled device shouldnt be a problem

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.

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 phone 😛

Please don't do that. Flaunt Infinia.

Learning new things everyday from the learned members. Thankyou sir for a simple yet fulfilling explanation.

My pleasure 😊

Did not have a problem with Magnus or One Card ever.

Frequent problem with Infinia and Aurum.

100% success rate with Infinia if you flip it around and tap near the NFC icon. My best guess is the thickness of the card is a major factor. Hence, the need to tap right on the NFC icon.

Try to hit harder with the card, glass and metal need to love each other in order to get the transaction flow. 😀

Only 1 side which has the nfc icon works in infinia for contactless payment
