They will also have to give their name and phone number for the purpose of contact tracing.
Adult customers in pubs and restaurants must show their Covid certificate and photo ID at the door of such establishments in order to verify they have been vaccinated against or recovered from the virus.
The reports come as draft guidelines for the return of indoor hospitality are set to be published later on Friday, ahead of the return of partial indoor service
on Monday.
Under the new guidelines, customers will need to provide their name and phone number for the purpose of contact tracing. Previously, only one patron per table had to provide this information.
Hospitality operators will also use a digital scanner to check customers' Covid status, with only the official Digital Covid Certificates being accepted, as opposed to cards from GPs or vaccination centres.
Hospitality representatives met with Fáilte Ireland and government officials earlier today, with the draft guidelines for the sector set to be published this evening at around 7pm.
This is in order to give the hospitality sector time to prepare for the return of indoor service on Monday.
That said, it is believed the regulations which will legally support the guidelines will not be signed into law today as some details are still being worked through.
It had previously been revealed that indoor hospitality will return from Monday in pubs and restaurants for people vaccinated against or recovered from Covid-19.
Under the guidelines, time limits for those permitted to eat and drink inside bars and restaurants will be scrapped, though there will be a closing time of 11.30pm.
