How is the power of QuardlockTM Advanced Card generated to activate the fingerprint and the display?
QuardlockTM Advanced Card has a built-in battery that can last for up to 120 standalone usages. The battery can be recharged with an NFC reader. QuardlockTM Advanced Card also has energy harvesting technology implemented that enables the card to work without using energy from the battery when in close contact with NFC readers. In some cases where the NFC reader or POS terminal is not transmitting sufficient energy the battery in the card will kick in and provide the extra energy needed to operate the card. This feature ensures that the card will always work with any NFC reader or POS terminal.
