If UK businesses don't accommodate higher security requirements by 19 September, they could miss salary payments.


Older internet protocols will be switched off on 19 September by the company behind Direct Debit and Bacs Direct Credit, which is used to pay 90 percent of the UK's workforce.


Businesses that don't make the appropriate changes to software and IT will find they'll be locked out of Bacs from the deadline date. UK businesses have been warned of the change for the past 16 months.


Improved security measures will be adopted at the end of this year by the global internet community. During that time, all organisations that need to communicate securely with users across the internet and via extranets will be affected.


Organisations that have yet to adopt compatible internal IT and appropriate software and cannot access Bacs to submit payment files should contact their software solution provider for help prior to next week's deadline.
