(v) "Stored value" means monetary value representing a claim against the issuer that is stored on an electronic or digital medium and evidenced by an electronic or digital record, and that is intended and accepted for use as a means of redemption for money or monetary value or payment for goods or services. The term does not include a credit card voucher, letter of credit, or any stored value that is only redeemable by the issuer for goods or services provided by the issuer or its affiliate, except to the extent required by applicable law to be redeemable in cash for its cash value. ------- This appears broad enough to include Facebook Credits, bitcoins, etc.
