Guest books at pubs and restaurants that may help trace customers if there is a coronavirus outbreak linked to a premises are a possibility in Northern Ireland.
But until final guidance is crafted by the Executive, likely following the lead from London this week, it is not something that is definite, said Colin Neill, chief executive of Hospitality Ulster.
UK Health Secretary Matt Hancock on Sunday said the use of guest books is being considered in England.
Guidelines for bars to reopen here, initially on July 3 for those serving food and for outside table service for drinks only, are likely to be revealed early this week after the UK Government announces its plans.
One of the guidelines most keenly anticipated by the hospitality industry is over the decision on whether there will be a one or two-metre distancing requirement within bars and restaurants. Pub owners argue it will be impossible for many operators to stay open under a two-metre policy.
Drinkers at pubs and bars in England may have to leave their names and contact details in a guest book so they can be swiftly traced if they come into contact with a punter who tests positive for coronavirus, according to reports.
Mr Neill said that is a possibility here, but it is not something that is included in his organisation's proposed guidelines, which are at an advanced stage.
"It is something that could be done," Mr Neill added.
The industry representative said whatever the UK Government lays down, either today or tomorrow, will likely inform the guidance from the Executive.
Apart from the social distancing rule, the industry is also keen for a date to be set to reopen non-food bars, which may be as early as July 4 in England and Wales.
The Republic has pencilled in July 20 for the opening of all premises.
Officials in England are understood to be looking at the guest book measure in order to fulfil the ambition of reopening the hospitality sector as early as July 4 and to aid the NHS test and trace programme.
Diners leaving their contact details at restaurants when making reservations could also play a role in helping tracers track down possible cases so they can self-isolate for 14 days.
Mr Hancock also said customers will be encouraged to order drinks through apps.
Bars are already preparing for reopening ahead of receiving any detailed advice and guidance from the Executive and health agencies.
Paul Blaney, owner of the Parador Lodge on the Ormeau Road in Belfast, has installed screens between tables among other measures, including non-touch hand sanitiser dispensers and a one-way system throughout the bar, including to and from the toilets.
Mr Blaney said he particularly wants his older customers, some of them isolated in care homes or sheltered housing for months, to be comfortable and feel safe to return.
Other bar owners have questioned the wisdom of increased table service as staff will be moving constantly from the bar to tables, and between customers.
They are also wondering about the decision to open again on a Friday rather than on a Monday or other weekday, which it is argued would allow staff to prepare better instead of being thrown in to a potential weekend rush.
