RFID / NFC cards, key tags and coins typically last for years but are subjected to the daily wear and tear depending on your usage. As such, we will offer a 7-day warranty to cover defective-on-arrival products. For cloning services, do take note that the access will be identical to the original card. If the original card access gets revoked by the landlord/facility management, the cloned card will also cease to work. This is something that we cannot provide warranty for.
