Australian company High Frequency designed a “self-service” linen portal for a commercial laundry servicing the thriving short-stay accommodation market.
Called the “Mobile Linen Hub”, this modified shipping container provides access to linen for users 24/7. After taking the linen they need, the cost is then added to their account as they exit the hub.
Access control with Wiegand 125 kHz reader
High Frequency’s initial prototype used a standard Wiegand 125 kHz reader to control access. Each customer’s card, upon scanning, granted entry to the Mobile Linen Hub while activating UHF readers inside.
However, the prototype encountered several problems with its 125 kHz Wiegand readers. The readers’ lack of security allowed cards to be copied, and their lack of data storage prevented them from displaying why a card had been declined, for example.
Reasons for denied entry
Ultimately, the inflexibility of a 125 kHz reader led to confusion and a lot of support calls
Customers only heard a ‘denial’ buzz and saw a red light. Meanwhile, there were multiple reasons a customer could be denied entry.
Their card could be invalid, their account could be suspended from non-payment, or simply, someone else could be using the Mobile Linen Hub. Ultimately, the inflexibility of a 125 kHz reader led to confusion and a lot of support calls.
MIFARE DESFire reader
High Frequency solved the problem by switching to Idesco’s 8 CD 2.0 D Pin RFID display readers. “A highly secure MIFARE DESFire reader, 8 CD 2.0 D Pin instantly solved our card cloning issue, with zero impact on our solution since Idesco handles both our card encoding and reader programming," notes Isaac Hayes, High Frequency.
“Our new system deployed a single Idesco reader on both sides of our Mobile Linen Hub, connected to an RS485/Ethernet converter, with our bespoke software communicating with them across OSDP," Isaac continues.
Display reader solution
High Frequency discovered that the OSDP standard made displaying private messages in an RFID reader possible
This new display reader solution has greatly decreased support call frequency while increasing the product’s usability. Confusion surrounding denied access was also solved, with the reader displaying messages on its screen for users, such as “Access Granted”, “Access Denied, Account on Hold” and “Portal Busy, please wait before entering”.
While looking for a new solution for their system, High Frequency discovered that the OSDP standard made displaying private messages in an RFID reader possible. “During my research, it became apparent that Idesco was the only reputable company with a color display, OSDP-compatible reader”, Isaac Hayes recalls.
Mobile access solutions enhancing security
“Idesco 8 CD 2.0 D Pin reader is now an integral part of Mobile Linen Hub’s design, and will be included in all manufactured models for the foreseeable future," he reports. Idesco Oy is a pioneer of RFID technology, with more than 30 years of experience.
Idesco RFID readers and transponders, mobile access solutions, controllers, and touch screen devices. Its products collect data and enhance security in several access control, vehicle identification, and logistics settings around the world. High Frequency specializes in helping commercial laundries around the world implement RFID in a way that provides value to their business.
