How to say "token" in Japanese

• 札ふだCommon
  nounHere 'token' is the physical sense: a small card, tag, or slip that stands in for something, in line with its 'ticket' and 'check' senses — a token kept or shown as proof.
• 字句じくCommon
  nounThis is the technical sense: a token as a unit of text — a word or string treated as a single item — in computing or linguistics, where it concerns wording rather than meaning.
  君きみはあまり字句じくに拘泥こうでいしすぎるよ。↗

  You are too much letter-bound.
• コインCommon
  nounA coin-shaped token: a metal disc used in place of money, as in machines or games — the same object as a 'slug'. It does not cover abstract or textual senses of 'token'.

Use 札 for a physical card- or tag-like token standing in for something, 字句 for the technical 'token' of computing and linguistics, and 「コイン」 for a coin-shaped metal token used in machines.
