The ISIS Code is the online shopping industry charter setting out standards
of service.

The ISIS Trust Scheme, and associated ISIS Mark, certify good performance by
e-retailers as defined by the ISIS Code.

The ISIS Code states that:

• All e-commerce services should be legal, decent, honest, truthful and
  fair.
• All e-commerce services should be operated with a sense of responsibility
  to consumers and to society.
• No merchant should bring e-commerce or ISIS into disrepute.
• The Code is applied in the spirit as well as in the letter.
  

ISIS Trust Scheme certification requires organisations to:

• comply with the ISIS Code;
• have its web site and service reviewed and monitored by ISIS;
• have its Business, VAT and Data Protection registrations checked by ISIS;
• remove the ISIS Mark if ISIS believes there has been a severe or continued
  breach of compliance with the Code or the ISIS Mark standard.
