The digital mobile access card turns your phone into a convenient mobile access credential, integrating BLE, QR code, and NFC access methods to make everyday entry simpler and more convenient. BLE Door Sensing Trigger access simply by approaching the door lock. Sensing range can be adjusted to fit the environment (short/medium/long range), with support for multiple trigger gestures — shake, wave, or rotate your phone — so you can choose the mode that suits you best. QR Code Access Generate a unique QR code for access readers to scan and verify — ideal for visitors or temporary access needs. NFC Access Card Once card registration, provisioning, and activation are complete, you can gain access through NFC-enabled access control devices. In supported scenarios, simply hold your phone near the sensor to complete verification, making entry and exit more intuitive and convenient. All three access methods can coexist depending on the on-site equipment, and can be switched between within the same app — no need to install multiple apps. This app must be used with supported access card readers (PXR-92MWS-BE / PXR-QMWS / PXR-QRMNSL / PXR-QRMNSL) and compatible access control hosts/door lock hardware. Actual available features depend on the on-site equipment deployment — please contact your facility administrator or system vendor to confirm which features are enabled.
