Abstract
A method for secure approval of a check includes: reading a machine-readable code to obtain a block identifier and a validation value, wherein the machine-readable code is displayed on a physical check and encoded with the block identifier and validation value; receiving a digital signature from an external device; identifying a blockchain data value stored in a blockchain, wherein the blockchain data value includes at least the block identifier and an additional value; validating the received digital signature using a public key; validating the validation value based on a comparison of the validation value to the additional value; and approving use of the physical check to fund a payment transaction upon successful validation of the received digital signature and validation value.
