If you are planning on attending a concert any time soon, there are a few things you may need to have in addition to your ticket.

According to Billboard, Ticketmaster is in the process of developing technology that concert-goers can use when entering venues to prove they have a negative COVID-19 test or the vaccination. Customers will be able to use their cellphones to verify that they’ve been administered the vaccine or that they have had a negative COVID-19 test within 24 to 72 hours before the show.

Details around the plan are still being finalized, but it will consist of three components, including “the California-based company’s digital ticketing app, third-party health information firms like CLEAR Health Pass and testing/vaccination distributors like Labcorp or CVS Minute Clinic,” reports the New York Post.

Concert attendees would have to have the lab send over their results to companies such as IBM’s Digital Health Pass and CLEAR Health Pass and they would verify the person’s status to Ticketmaster. Anyone who tests positive or does not get screened will not have access into the event.

These new proposed regulations come just days after Pfizer announced that the results from their trial showed their vaccine as 90 percent effective. “Today is a great day for science and humanity,” Pfizer Chairman and Chief Executive Albert Bourla said. “We are reaching this critical milestone in our vaccine development program at a time when the world needs it most — with infection rates setting new records, hospitals nearing over-capacity and economies struggling to reopen.”

Ticketmaster president Mark Yovich says the demand for digital screening services will increase once a vaccine is approved. “We’re already seeing many third-party health care providers prepare to handle the vetting — whether that is getting a vaccine, taking a test or other methods of review and approval — which could then be linked via a digital ticket so everyone entering the event is verified,” he told Billboard.
