Read supported NFC tags. Copy 26-bit HID RFID credentials to compatible T5577 blanks, then verify with fresh reads. LongYan_V1.0 reader required. Read supported NFC tags and copy compatible 125 kHz HID RFID credentials with your Mac and a LongYan_V1.0 Bluetooth reader. NFC support is read-only. Writing is limited to supported 26-bit HID (H10301) credentials on compatible T5577 blanks. This version does not write NFC tags. RFID READING, WRITING AND VERIFICATION • Read supported 26-bit HID RFID credentials, with a dedicated HID-only scan option. • Copy supported H10301 credentials onto compatible T5577 stickers or tags. • Follow five steps: connect, read and save, check the original, write, then verify. • Confirm the original matches your saved read before swapping in a blank. • Confirm every write yourself. The app never retries a write automatically. • Verify the destination with two fresh reads separated by an empty-reader check. • Check an interrupted copy using read-only recovery, without writing again. NFC READING AND INSPECTION • Detect NFC Type A tags and report unsupported layouts. • Read identifiers and up to 47 user-data blocks from the supported Classic-style layout when the factory key permits access. • Inspect the returned data and see when a read is incomplete. • NFC writing, manufacturer blocks and security-sector data are not supported. SAVE, BACK UP AND COMPARE • Keep originals in a local saved-read library. • Import and export saved reads as files. • Compare a saved record with a fresh tag read. • Keep identifiers hidden until you choose to reveal them. HARDWARE AND COMPATIBILITY LongYan_V1.0 is the only supported reader in this version. A Mac alone cannot read tags. Other readers and RFID formats are not supported. Use only tags you own or are authorized to copy. Protected data cannot be copied. You must confirm the destination is a compatible, expendable T5577 blank; the app cannot identify its chip automatically. A write may permanently lock or damage the blank. Verification confirms matching credential data, not acceptance by a door reader or another access system. ONE-TIME WRITING UNLOCK Reading, saving, importing, exporting, comparing and read-only recovery are free. A one-time in-app purchase unlocks supported 125 kHz HID RFID writing. NFC writing is not included. No subscription. PRIVATE BY DEFAULT Tag contents and identifiers stay on your Mac unless you export or share them. No app account is required. Usage statistics and scrubbed crash reports are optional and off by default.
