võtmekaart

Võtmekaart is an Estonian term that translates to "key card" in English. It refers to a card, typically made of plastic, that is used for a variety of access control and identification purposes. These cards often contain embedded electronic components, such as magnetic stripes, barcodes, or RFID (Radio-Frequency Identification) chips, which store information that can be read by a corresponding reader.

The most common application of võtmekaart is in hotel rooms, where they function as electronic keys to unlock doors. They can also be used for employee identification and access to secure areas within a company. In some cases, võtmekaart might also be used for public transportation systems, loyalty programs, or as a form of payment or stored value. The specific functionality of a võtmekaart depends on the technology integrated into the card and the system it is designed to interact with. The security and convenience offered by võtmekaart have led to their widespread adoption across various industries.
