Tagsmith: NFC Reader & Writer

Scan any NFC tag and see everything it holds — then write your own. A complete NFC toolkit: a reader that shows every detail a tag will give up, and a writer that puts text, links, Wi-Fi credentials and contacts onto blank cards. READ ANY TAG Hold a card to your phone and get the full picture instantly: • UID in hex, reversed hex and decimal — access systems disagree about which format they mean, so all four are shown • Card type and every technology the tag supports • Chip details: ATQA, SAK, memory size, sector and block counts, transceive limits • MIFARE Classic and MIFARE Ultralight specifics • FeliCa, ISO 15693 and ISO-DEP parameter • The full NDEF message, decoded record by record WRITE TO BLANK OR REUSABLE TAGS Ten record types, written with a single t • Text • Contact card (vCard) • Website link • Wi-Fi network — share access without reading • Phone number your password out loud • Email • App launcher • SMS • Custom MIME type and pa • Location Unformatted tags are formatted automatically, so a blank card takes one tap, not two. POWER TOOLS • Batch write — program a run of cards without returning to the editor • Scan history — every tap saved automati • CSV export — hand your scans straight to a spreadsheet • Password protection — lock NTAG213/215/ password, with optional read protection • Permanent lock — make a tag read-only f PRIVATE BY DEFAULT Everything happens on your phone. No account, no sign-up, no servers. Your tag data is never uploaded anywhere, app asks for is NFC. WHAT IT WORKS WITH NFC tags at 13.56 MHz: NTAG213/215/216, M NFC Forum Types 1–4, FeliCa, ISO 15693 and ISO 14443 A/B. Please note: this uses your phone's built-in NFC reader. It cannot read 125 kHz access fobs or UHF inventory tags you use. Your device needs NFC hardware. (The write list is a single column in the actual file — Play doesn't render columns.)
