Does ViArt support payments via HSBC?
Amongst the files for ViArt Shop v.3.5, there are four files whose names begin with the letters "hsbc":
1. hsbc_cpi.php
2. hsbc_cpi_check.php
3. hsbc_cpi_direct.php
4. hsbc_cpi_functions.php
Each of these files has a comment at the top, saying, "The Cardholder Payment Interface (CPI) within HSBC Secure ePayments (http://www.hsbc.com/) [...] transaction handler by www.viart.com".
However, I can find no reference to these files anywhere else in the ViArt system, and I can find no mention of HSBC on the ViArt website. In particular, HSBC is not mentioned in ViArt's list of "Supported payment systems" on the following page:
http://www.viart.com/online_store_features_list
So can HSBC Secure ePayments be made through ViArt, and if so, how? How are the four PHP files that I listed above actually used?
Any help would be much appreciated!
