A transaction card assembly and method for forming a transaction card assembly. The transaction card assembly may include two or more transaction cards that are each useable with different issuers. A first transaction card may be useable only with a first issuer, and the second transaction card may be useable with one or more entities other than the first issuer. The transaction card assembly may be formed from a same piece of material and may include one or more machine-readable features, such as a barcode, magnetic strip or electronic device. The transaction cards may meet ANSI and ISO specifications, e.g., after the cards are separated from each other without the use of tools.
