Abstract: Depositing funds onto smart cards for use during processing of purchases. A device creates a deposit request and transmits the request to a remote system. The remote system processes the request and transmits a deposit record to the device, which in turn transmits the record to the smart card. If the device has network access, it transmits a deposit confirmation to the remote system, which updates the smart card account to include the confirmation. If the device unable to connect to the remote system, the deposit confirmation is transmitted when the smart card is involved in a future transaction. During the future transaction, the smart card transmits its transaction history, which comprises the deposit confirmation, to the device, and the device transmits the transaction history to the remote system. The remote system updates the smart card account to include the deposit confirmation.

Abstract: A credential such as a One Time Password (OTP) can be proffered as a matrix of characters provided by a user. The verifier can accept that credential if it determines that the matrix is rank one. If it determines the matrix is not rank one, it can reject it or treat it as possibly corrupt due to one or more erroneous or missing entries. The verifier can factor the received matrix into two vectors and create a rank one projected matrix that is the product of the two vectors. The verifier can measure the distance between the received and projected matrices and accept the credential if the distance is within a distance threshold.

Abstract: Preventing fraud during an offline transaction by encoding a randomly-generated card verification code onto a smart card. The verification code is transmitted to a contactless device during each transaction, wherein it is cross-referenced with the account number to ensure presence of the card. Also, every transaction record is signed by an access key resident on the contactless device and certified by a signing key resident on a remote system. Funds may be deposited onto the card when the contactless device creates a deposit request, signs the request using an access key and transmits it to the remote system, which in turn processes the request and certifies it with a signing key. Funds may be withdrawn when the contactless device creates a withdrawal record and signs it using an access key. The remote system verifies the signatures and certifies the records using a signing key when the records are later transmitted.
