All C•ntactless Business Card (NFC chip only) comes with a 6 months warranty, under these circumstances:
Unable to scan NFC on multiple devices
Did not come in contact with water.
Not physically damaged We do not cover the card in our warranty if the card is physically damaged in any way. Our card has been through a stress test (sitting on it, sitting on it while it is in a wallet, bend test, etc…) to ensure that it survives hash environment, but we will still recommend that you take extra care of the card as too much pressure might cause the card to bend over time. The card will still work if it’s bent, but it will not look as professional if you are presenting it to a friend / customer.
