ABSTRACT OF THE DISCLOSURE A check verification and transaction method in which a payee of a check is identified by a personal identification number PIN. A data encryption algorithm is applied to the PIN i to produce a first number that is recorded on the check. Afterward, a PIN is ascertained from a bearer on the check, and the same data encryption algorithm is applied to the PIN as ascertained from the bearer to produce a second number. The first and second numbers are compared, and an indication is produced if the first and second numbers do not coincide. The data encryption algorithm, instead of being applied to the PIN alone, may be applied to the PIN and to a further number together to produce the first number, the further number also being recorded on the check. Advantageously, the further number may be a check sequence number or an amount of the check. The method validates the authenticity of the check being presented for payment, the eligibility of the individual presenting the check, and the validity of the relationship between the two. The authenticity of the check being presented for payment is validated by means of a "check derivation" printed on the front of the check at the time of issue and computed from the PIN of the named payee and a secondary key, also printed out on the front of the check. The eligibility of the individual presenting the check is validated by means of eligibility information to be read by the person cashing the check and stored on a card, preferably an integrated circuit card, or "smart card". The validity of the relationship between the check being presented for payment and the individual presenting the check is also verified by means of a check derivation, since the individual presenting the check must be capable of entering the PIN of the named payee of the check in order for the check derivation to be correctly and independently produced by a transaction terminal at the point of use.
