RFID Tester Hold a tag against your iPhone and see at once what is on it: the UID and the detected tag type. Scans land in the history, where you can comment, group and search them. WHAT YOUR IPHONE CAN READ β€’ MIFARE / NTAG (ISO 14443) – NFC stickers and tags, access cards, tickets β€’ ISO 7816 (ISO 14443) – smart cards and ID cards; only the UID is read β€’ ISO 15693 – vicinity tags, library and industrial labels WHAT DOES NOT WORK β€’ 125 kHz and 134 kHz (EM4100, HID Prox, T5577, pet chips) – the iPhone has no reader for this frequency; such tags are never detected during a scan β€’ UHF, 860–960 MHz – EPC Gen2 labels from logistics and retail need a dedicated reader β€’ Anything without NFC: Bluetooth trackers, QR and bar codes, proprietary radio keys The iPhone only reads NFC at 13.56 MHz. The app tells you up front instead of leaving you guessing – a built-in overview always shows which tag types work and which do not. SCANNING AND READING β€’ UID as hexadecimal, decimal or binary – switchable, no conversion by hand β€’ After every scan you see which tag family was detected β€’ Every scan is logged with date and time ORDER IN THE HISTORY β€’ A comment on every tag – "facility manager", "left shelf", whatever you need β€’ Filter by duplicates and by whether a comment is set β€’ Reset single entries or the whole history GROUPS β€’ Collect UIDs in groups – per building, vehicle or tool checkout β€’ Every group with a name and a description β€’ A separate comment for each UID inside the group β€’ Duplicate detection across all groups and the single history: you see at once when a tag is already filed elsewhere β€’ Search across group name, description, UID and comment β€’ Scan a tag and jump straight to its group SCOPE Single RFIDs without a limit, plus up to 5 groups with 10 UIDs each. WHO IT IS FOR Electricians, service technicians, facility management, workshops and warehouses – anywhere access cards, tool or inventory tags have to be told apart. REQUIREMENTS iPhone with NFC reading, iOS 18.0 or later. All data stays on the device.
