R.I. Gen. Laws § 42-61.1-5: Simulation of checks and invoices.

In connection with a consumer transaction, no person shall issue any writing that simulates or resembles:

(1) A check, unless the writing clearly and conspicuously discloses its true value and purpose, and the writing would not mislead a reasonable person; or

(2) An invoice, unless the intended recipient of the invoice actually contracted for goods, property, or services for which the issuer seeks proper payment.
