1. A computer-implemented method for improving the function of a computer for depersonalizing transactions being switched between an acquirer system located in a first country and an issuer system located in a second country by a switching service during a financial transaction, the computer-implemented method comprising:
sending a personalized particular transaction and an associated transaction identification from the acquirer system located in the first country to a depersonalization service via an independent communications channel which is independent of the switching service;
depersonalizing the personalized particular transaction at the depersonalization service to produce a depersonalized particular transaction;
sending the transaction identification and the depersonalized particular transaction from the depersonalization service to the acquirer system located in the first country;
sending the transaction identification and a reverse depersonalization dictionary from the depersonalization service to the issuer system located in the second country;
sending the depersonalized particular transaction from the acquirer system located in the first country to the issuer system located in the second country via a communications network operated by the switching service;
reversing the depersonalization of the depersonalized particular transaction at the issuer system located in the second country using the reverse depersonalization dictionary to produce a repersonalized particular transaction;
processing the repersonalized particular transaction at the issuer system; and
sending a normal response code from the issuer system located in the second country to the acquirer system located in the first country and to the depersonalization service,
wherein neither the personalized particular transaction nor the repersonalized particular transaction are sent between the first country and the second country.
