VAKA supports EM, MIFARE, and Radio reading. These are activated separately in Settings -> Card/Code -> Tags.
Personal codes can be used as an alternative to tags. You activate or deactivate these in Settings -> Card/Code -> Personal code. When personal code is enabled in the system, group code and the caretaker function temporary code cannot be used.
Additional Identities are used to assign a person more than one access tag, card, or radio key. Additional Identities are activated in Settings-> Card/Code -> Advanced -> Permit assigning additional identities. The identities are assigned in the Additional Identities tab for each person.
