Does the NFC tag from Scard will cause interference with the office security card?

We don't think it will interfere with your office security card if you are not using the same face where you paste our NFC tag on your card. The same applies to tapping our NFC tag to exchange cards with your prospect. Because most security cards are RFID cards, even if you have NFC security cards, most likely, our tag will not affect yours because our tags come with anti-metal backing.
