The government said it will fix the Thailand Pass system after glitches following its launch last Monday when the country reopened to foreign visitors.

The move comes after complaints by some tourists that they had either experienced delays in receiving QR codes or in some cases had not received them at all, following the approval of their travel applications.

A government spokesman said on Sunday that Prime Minister Prayut Chan-o-cha has been told about the problem and instructed state agencies to fix the new online system.

Those wishing to visit the kingdom should go to tp.consular.go.th.

Immediate approval was one of the features of the platform for applicants whose vaccine certificates can be verified online by QR code.

Once they have received approval, travellers can download the Thailand Pass QR code which enables them to prove their eligibility to airline and screening officers. They must also present negative Covid-19 results from a test taken no later than 72 hours before travel.

One Pheu Thai MP said he had received complaints from Thais overseas who registered for Thailand Pass that the system was slow.

Some said they booked their flight one year in advance to return to Thailand, but when they were about to fly, their application was still not approved.
