| 1. UHF item-level locker | UHF RFID, commonly based on ISO/IEC 18000-63 (EPC Class 1 Gen 2) | UHF tags on items are read by antennas installed in or around compartments. | Libraries, tool rooms, uniforms, and shared equipment with tagged items | Can identify multiple tags without requiring each item to be presented individually. | Metal, liquids, tag placement, and nearby tags can affect read performance; compartment-level tuning and testing are important. |
| 2. HF/NFC credential-access locker | HF RFID at 13.56 MHz; NFC-compatible credentials may be used where supported. | A person presents a card, key fob, or compatible mobile credential to a reader. | Personal storage, staff lockers, campuses, and membership facilities | Intentional close-range presentation supports straightforward user access workflows. | Credential compatibility depends on the reader, credential technology, and system configuration; NFC support should be verified. |
| 3. Hybrid UHF item tracking + HF/NFC access | UHF for item detection, combined with HF/NFC for user authentication | Users present a credential; UHF readers detect tagged contents during configured events. | Equipment checkout, managed uniforms, and controlled supply storage | Separates user identification from item identification, enabling both access control and inventory records. | Requires integration between access, item-reading, and software components; test read accuracy in the final enclosure. |
| 4. HF item-level compartment locker | HF RFID at 13.56 MHz, with item tags and compartment-mounted readers or antennas | Items are detected in a defined compartment or at a presentation point. | Small tagged assets, documents, and controlled handover processes | Shorter read range can help limit reads to a specific presentation area when properly designed. | Usually requires items to be positioned close to the reader; read range and tag orientation vary by installation. |
| 5. UHF shared-access pickup locker | UHF identification of tagged parcels or goods, with electronic access control | A code, credential, or application authorizes access; UHF can support item presence or collection records. | Order pickup, internal mail, and distribution points | Can pair convenient collection workflows with automated item identification. | RFID does not itself verify a person’s identity or prove collection; access rules and event logging must be configured separately. |
| 6. HF/NFC smart personal locker | HF/NFC user credential reader; item-level RFID may not be included. | A compatible card, fob, or supported mobile credential unlocks an assigned or shared locker. | Offices, gyms, schools, and visitor areas | Simple user experience and flexible assignment options when connected to a suitable access-management system. | This configuration controls locker access but does not automatically track the contents inside. |
| 7. Multi-technology hybrid locker | UHF item identification plus HF/NFC credentials; optional barcode or keypad as an additional access method | The system combines credential-based access with item reads and, where configured, a secondary identification method. | Sites with varied users, tagged assets, and operational fallback needs | Supports different workflows and can provide an alternate way to identify users or items. | More technologies increase integration and maintenance complexity; define which method is authoritative for each event. |
