KeyTag","description":"\u003cp\u003e\u003cb\u003eOneKey KeyTag\u003c\/b\u003e is a pair of titanium plates for storing your recovery phrase. Instead of writing the words on paper, you punch dots into the plate with the tool in the box. Each plate is about a quarter the size of a credit card, fireproof, waterproof, and small enough to carry.\u003c\/p\u003e\n\u003ch3\u003eWhy metal, not paper\u003c\/h3\u003e\n\u003cp\u003eThe paper card in your wallet box works, until one fire, one flood or one termite nest. Thailand is humid most of the year, and paper kept for years fades and crumbles on its own. Titanium has none of these problems.\u003c\/p\u003e\n\u003cp\u003eMore importantly, if the recovery phrase is lost, the assets in the wallet are lost with it. Nobody can recover them, not us, not anyone.\u003c\/p\u003e\n\u003ch3\u003ePunch dots, not letters\u003c\/h3\u003e\n\u003cp\u003eEvery recovery word comes from the BIP39 standard list of 2,048 words, and each word has its own number. KeyTag records that number instead of the letters. Each row on the plate is one word: look the word up in the printed word list, then punch a dot in the boxes the list marks.\u003c\/p\u003e\n\u003cp\u003eTo read it back, add up the numbers of the punched boxes in that row, then look the total up in the list. Do that for every row and you have the full phrase. This is what keeps the plate so small, and a full backup takes only minutes.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTC4 titanium alloy, the same grade used in aerospace, with a melting point of 1,668 degrees Celsius\u003c\/li\u003e\n\u003cli\u003e36 x 33.5 x 3 mm, 14 grams per plate\u003c\/li\u003e\n\u003cli\u003eOne plate holds 12 words plus one spare row; the pair holds a full 24 words\u003c\/li\u003e\n\u003cli\u003eWaterproof and resistant to acids, alkalis and chemical corrosion\u003c\/li\u003e\n\u003cli\u003eWithstands extreme heat and extreme cold\u003c\/li\u003e\n\u003cli\u003eWorks with any brand of wallet that uses a BIP39 recovery phrase, 12 or 24 words\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 KeyTag plates\u003c\/li\u003e\n\u003cli\u003e1 automatic center punch\u003c\/li\u003e\n\u003cli\u003e1 guide with the BIP39 word list\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eMy wallet uses a 12-word phrase. Do I need both plates?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. One plate holds all 12 words. Keep the second as a duplicate stored somewhere else, or use it for another wallet.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIf someone picks up the plate, can they read the words?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThey see dots, not words. Without the method and the word list, nothing can be read at a glance. But this is not encryption: anyone who knows the method can decode it, so keep the plate as private as you would keep a paper backup.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I fix a wrong punch?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eNo. A punched dot cannot be removed. Mark the dot positions for every word in the guide first, check them against your device once more, then punch.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow is this different from OneKey Lite?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eOneKey Lite is an NFC card that stores the recovery phrase encrypted and needs the app and a PIN to read it. KeyTag is solid metal with no chip: no app, no power, and readable years from now with nothing but the word list. Choose Lite for convenience, KeyTag for the most durable backup, or use both together.\u003c\/p\u003e\n\u003ch3\u003eONE RULE TO REMEMBER\u003c\/h3\u003e\n\u003cp\u003eAnyone who asks for your recovery phrase is a scammer. No exceptions.\u003c\/p\u003e\n\u003cp\u003eNeither SIAMBC nor OneKey will ever ask for it, whatever reason is given: warranty claims, identity verification, system updates or account recovery. Those words are the key to your funds.
