A method of verifying the identity of a user by comparing a biomorphic sample from the user with a stored biomorphic pattern of the user, without access to an online database of encoded biomorphic patterns. An authorization process receives an encoded biomorphic pattern from the user, the encoded biomorphic pattern stored on a storage device containing a processor. The processor is powered by a device capable of reading the storage device. The authorization process verifies the encoded biomorphic pattern is a valid biomorphic pattern with a valid expiration date, and compares the encoded biomorphic pattern on the storage device to a biomorphic sample provided by the user, in order to grant access to the user. If an online database is available, authorization process transmits the result to the online database and receives, in return, an updated expiration date. The authorization process updates the storage device with the updated expiration date.
