Ko te eti holo ko te tohu whakapiri he whakariki tūhurahura e whakamahia hei whakangungu i ngā whinga kaitono, e whakapai ana i ngā hanganga mārama me ngā mahi whakahaere. Kei roto i ēnei tohu matatika ngā wharangi tuatahi e whakaputa ana i ngā pūmau whakaaturanga toru tauira i runga i te marama. Ko te mahi whakamahi ka whakamahi i ngā rorohiko horopū tūhuratia ki te hanga i ngā raupapa itiiti e whakaputa ana i te hokohoko holo, mea atu ka whai wāhi ano te tiketiki hei whakamātau, ko te mutunga kaore e taea te whakaaweawe. E ai ki te take o te tohu holo, e pa ana ki ngā whakahaere nui, nō te mea he whakaae kaiwhakahaere i ngā mea hoko me te tiaki i ngā taonga pūtake. Ka taea te whakatika i ēnei tohu me ngā whakahaere tirotiro rerekē, inaianei ko te tuhituhi koretake, ko te tuhinga itiiti, me ngā pūnaha nūmerikau whakarere. Ka whakapiri haere ki ēnei i waenganui i ngā momo kaiwhakapiri, inaianei ko ngā poraka, ko ngā parihana, ko ngā kākano, me ngā kaihiko papakete, ka noho pūmau tonu i aua mea puta noa i te ao o te mea hoko. Ka whakamana ngā hanga nei i ngā whakahaere tirotiro mōteatea me ngā whakahaere tirotiro koretake, me te whakaae tūhonotia e ngā kaiwhakamahi, ā, ka taea e ngā kaihangā me ngā kaitiaki tirotiro ngā mahi whakamātau whaihua. Nō te wā o nāianei, kei roto i ēnei eti holo ngā mahi mātauranga pūnaha rorohiko, inaianei ko ngā kōrero QR rānei ko ngā hanga NFC, ka whakamana i ngā mahi tirotiro pūnaha rorohiko me ngā mahi whakawhiti. Ko tō rātou whanaketanga ka tiakina i ngā whiuwheoro o te ao, inaianei ko te wai, ko ngā raru ukaipo, me te whiu UV.
