1 BEYOND BARRIERS Using advanced access technologies to improve the functionality and physical security of self-service systems

2 In the world of kiosks, ATMs, self-service terminals, vending machines and electronic lockers, software is typically a top design priority. However, hardware components that control access to the enclosure can be just as critical to the system s functionality and physical security. OEM engineers and system integrators can enhance their products and gain a competitive advantage by integrating advanced access technology. New materials and manufacturing techniques have antiquated conventional cylinder locks and transformed latches, hinges, handles, and levers from purely functional elements to devices that can actually enhance an enclosure s operation and physical security. Electronic access systems are no longer just locks and latches that simply provide barriers. They are intelligent systems linked to the system s software that can provide advanced vending functionality. Activated by purchase requests, these devices enable products and services to be dispensed appropriately. Beyond simple inventory that is uniform in size and shape (think beverage containers), intelligent systems can manage complex transactions that require multiple steps for goods of various dimensions, as well as the return of used stock to the machine. Thus, these systems make it possible to expand self-service units into markets previously unimagined. The devices can also control access to the enclosures by service and maintenance personnel and provide audit trails to document all of the service activity. With this kind of intelligence, owners can manage their self-service systems more efficiently, and it can even be done remotely. From Functional to Formidable Hardware, such as hinges, latches and handles should be evaluated by how they can contribute to the enclosure s functionality and security because the two are intertwined. Obviously, hardware must contribute to security by reducing opportunities for vandalism and theft. Internal and flushmounted hardware help eliminate pry points. New materials and manufacturing processes have created hardware that can resist damage from the vandal s favorites tools screwdrivers, cat s paws, scrapers, pry bars, etc. Enclosures are most vulnerable during regular replenishment and repairs. Improving the way service personnel and maintenance technicians interact with an enclosure (the ergonomics) can shorten the time that it is open, and thus reduce security risks. For example, some gasketed latches and handles can satisfy NEMA 4 and IP-65 standards for protecting the unit against water and dust penetration. Less water and dust means fewer service calls and, thus, fewer chances for security breaches. Detent hinges will hold access panels, doors and cover plates securely open or closed not swinging in between. Constant-torque position-control hinges, on the other hand, securely hold at any desired position in the hinge s operational arc not just in the fully opened position. Both of these specialty hinges allow service technicians to work without having to hold panels open. For outdoor systems, it means that panels will remain open in windy conditions. On indoor systems, these hinges will keep panels open even if the enclosure is off-kilter or the slab is not level. The Call for More With advances in technology, the average price-point of kiosk and vending transactions is creeping upward. This is closing the gap between their traditionally lower security needs and the high-level security used on ATMs. That growing price point is causing many vending and kiosk owners to specify the latest ATM-style electronic access technology and justifiably so. Regardless of the application, having a good understanding of electronic access technology options will help engineers and other system designers incorporate the right solution into the enclosure design. The heart of the most robust electronic access systems is a reliable, electromechanical lock or latch (EML). The EML design ultimately influences system electrical requirements, physical security, installation options and the industrial design of the overall system. Today s EMLs are robust, vandalresistant devices with built-in intelligence and mechanical

3 override options. For example, in a kiosk that rents chargers for electronic devices, the EML responds to the consumer s purchase request, unlocking a specific locker compartment. It also knows to secure the compartment door when the consumer retrieves their fully charged device and shuts the door. A high-quality EML provides added security over mechanical latches and adds tremendous possibilities for access-control monitoring. EMLs can transmit latch status with a simple indicator light or a sophisticated networked monitoring system, depending on the desired level of security and the sensitivity of the enclosure s contents. Today s advanced EMLs feature gear motor drives that provide higher load capabilities using less power than previous latches, reducing the kiosk s overall energy consumption. It is important to design the latch to overcome unforeseen loads as in the case of jam conditions. Human Touch Points After selecting the most appropriate EML, engineers should select suitable access control devices for their specific application. The human interface is an important component because it controls the way both customers and service personnel interact with the self-service system. Fortunately, there is a wide variety of access-control devices available from simple stand-alone keypads to radio frequency (RF) remote-control systems and sophisticated biometric readers. Customers typically need only enough entry into the machine to retrieve their product or service. The EML controls that entry through the software interface, and their access is restricted to the one compartment or locker that contains their purchase. On the other hand, repair technicians, money handlers and inventory managers have very different requirements. Owners may not want all of these service personnel having access to all parts of the enclosure. Access control technology exists to limit access to specific parts of the self-serve system. For example, the instrument panel door could use an electronic rotary latch that responds to the technician s key fob, while the latch on the product compartment doors could respond to a biometric reader. Both interfaces are easily reprogrammed when personnel change, safeguarding the kiosk from theft. Stand-alone keypads are convenient plug-and-play solutions that do not require software or network administration. They are also convenient because employees and service personnel do not have to carry a physical key or card. With this type of system, operators can manage and monitor unique user access codes and change codes without physically distributing new keys or access devices to employees. Another option is the electronic key. Personnel press this tiny device against the remote sensor to gain entry to an enclosure. Electronic keys are especially suited for applications where there are many users with different access privileges across a large number of enclosures. An electronic key system is easy to program and access can be added or removed without having to change the lock plug. Other access control options include proximity-based and remote RF control systems, which are wireless and noncontact solutions that can open locks and latches without physical contact. Security from a Distance A remote monitoring or a networked solution is the final piece to a full electronic access solution. Remote monitoring provides an added level of security for sensitive and highvalue assets. Each time that an EML opens or closes, a signal is sent to a remote monitoring system to confirm and log access, leaving an electronic signature and creating an audit trail of the event. For example, electronic locking rotary latches or swing handles contain sensors and multiple output signals that provide data for both local and remote monitoring, making the system ideal for ATMs and vending machines with high-value inventory, such as MP3 players and cell phones, that are appealing to criminals. A service employee could call a special number at headquarters when he is in front of the machine, and headquarters could initiate the release of the electronic latch.

4 Retrofitting for Intelligence Serving as both a locking/latching device and intelligent access interface, an EML offers a full range of retrofit options to update the security and control of existing enclosures. Many EMLs are also backward compatible with existing EAS infrastructure, such as card readers, fingerprint readers and PIN pads. This means that past investments can be scaled up as the organization expands. Keeping all or part of an existing system can significantly reduce deployment costs and enable faster integration. Retrofitting is also an issue in the continuing development of EML technology. Flexible EML designs simplify the integration with existing access solutions, mechanical or electrical. This includes how the EML works with the physical environment (such as mounting hardware and the EML s engagement with the physical enclosure), and with the existing electrical wiring, controls and power systems. Optimum security solutions provide all relevant information about the status of the locked compartment to remote monitoring locations. Defining the lock s electronic and physical states, as well as data on potential tampering, jam conditions and door closure status, gives the operator the best information possible. For example, is the latch locked, but door panel open? If a more intelligent system could recognize the difference, it could take security to a whole new level, all the way down to the actual point of access. Designers of self-service systems should give careful consideration to hardware that controls and affects access to the enclosure. Attention to these details can provide owners a greater return on an investment through improved control, increased functionality and reduced asset loss. While wireless options are in development, the majority of near-term innovations are focused on minimizing wiring and broadening compatibility. Retrofitting an EML with a user s current access control system means that the EML must accommodate existing power and control systems, which can cover a wide range of current and voltage requirements. Locking in on the Future As with any energy-consuming device, efficiency is an area for continuous improvement. The goal is to use minimal power while releasing under higher mechanical operating loads (i.e., resistance from stiff gaskets) and resisting higher mechanically applied loads from vandals. More efficient electro-mechanics have enabled battery-operated solutions that minimize wiring and reliance on separate power supplies.
