Best Practices for Electronic Lock Selection for Self-Service Applications

When designing physical security into self-service enclosures, such as kiosks and pick-up drop-off points (PUDOs), manufacturers must anticipate the need for modern methods of access control and incorporate new technology, while still providing a solution that is cost-effective and meets the requirements of the growing self-service industry. Incorporating appropriate electromechanical locks or latches (EMLs) into enclosure design is key to delivering an end product that delivers convenience, usability and above all, security.


Electronic access solutions can provide an indisputable access audit trail for all doors and cabinets secured electronically. Each time an EML-equipped enclosure opens or closes, a signal is sent to a monitoring system to confirm and log access. Depending on the configuration, EAS reporting can provide more than just simple open/closed information – such as which credential activated the EML and the time and duration of the event.

An EML serves as both a locking/latching device and intelligent access interface, offering a full range of retrofit options to update the security and control of existing enclosures for a variety of applications.

When selecting a quality EML, such as Southco’s R4-EM Electronic Rotary Latch, it should meet the following criteria:

  • Integrates easily with existing control systems
  • Provides simple and versatile installation options
  • Includes a mechanical override feature for manual release in case of power failure
  • Provides optimum efficiency to provide high mechanical strength while using minimum electrical power
  • Incorporates built in intelligence to allow for various locking features such as delayed re-locking, lock status monitoring, sleep mode and communication with external systems
