FIELD: computer equipment.
SUBSTANCE: invention relates to computer engineering. Method comprises steps of: receiving a limited-use key (LUK) from a remote computer; generating, using a communication device, a transaction cryptogram using LUK; sending a denotation to the access device instead of a real account identifier and a transaction cryptogram for conducting the transaction; sending to the remote computer a recharge request for the new LUK; and receiving a new LUK from the remote computer when the transaction log information in the recharge request matches the transaction log information on the remote computer.
EFFECT: technical result consists in improvement of protection of communication device during transaction.
