NFC tags for Google Review link with iPhone support

Customer:

I’m interested in NFC tags that can be programmed so that when a phone is tapped to the NFC device, it automatically opens a Google review form with a pre-filled 5-star rating and sample comment text.

Soldered Support:

For reliable tap-to-open review functionality across all phones, especially iPhones, use NFC Forum Type 2/4 tags like NTAG213/215/216 rather than MIFARE Classic 1K. iPhones typically don’t read MIFARE Classic in the background, and not all apps handle it well.

Google doesn’t allow pre-filling the 5-star rating or comment text via URL parameters. The safest approach is to use a direct review link with Place ID:

If you use an existing MIFARE Classic 1K tag (better support on Android):

  1. Install “NFC Tools” or “NXP TagWriter”
  2. Open Write → URL/URI and paste your review link
  3. Tap your phone and wait for confirmation

Note: If the tag was previously locked or keys A/B were changed, writing may fail.

Optional locking: After testing on multiple phones, you can lock the tag from the same app (Write → Lock) to prevent changes. This cannot be undone.

hvala na upitu! Misliš na ove NFC tagove? https://soldered.com/product/nfc-sticker-13-56mhz/

Ukratko, da, MIFARE Classic 1K naljepnica je “programibilna”, ali nije idealna za univerzalno otvaranje linka na svim telefonima (pogotovo iPhoneima). Za pouzdano “tap → otvori recenziju” iskustvo bolje je uzeti NFC Forum Type 2/4 tag (npr. NTAG213/215/216).
iPhonei u pravilu ne čitaju MIFARE Classic u pozadini, a ni svaka aplikacija ga ne piše/čita dobro.

Općenito, google dopušta direktan link do forme za recenziju, ali ne dopušta da unaprijed namjestiš 5 ★ ili upišeš tekst preko URL parametara (stare fore više ne rade). Umjesto toga koristi „review” link. Najsigurnija varijanta je s Place ID-om:

Ako ipak želiš iskoristiti postojeću MIFARE Classic 1K naljepnicu (bolje radi s Androidom):
Instaliraj „NFC Tools” ili „NXP TagWriter”. Otvori Write → URL/URI i zalijepi svoj review link. Prisloni telefon i pričekaj potvrdu.
(Ako je tag ranije zaključan ili su promijenjeni ključevi A/B, pisanje može pasti.)
Zaključavanje (opcionalno): Kad sve testiraš na više telefona, možeš „zaključati” tag da nitko ne promijeni sadržaj. To radiš iz iste app-ice (Write → Lock). Ne može se poništiti.
