How Does iPhone Read Tiny NFC Tags? | 4.5 x 1.8mm?

iPhone Read Tiny 4.5mm 1.8mm NFC Tag PCB First you have tiny NFC tags. Next you need to know how does iPhone read tiny NFC tags? This post shows two types of 4.5mm x 1.8mm PCB NFC tags you read with your iPhone.

iPhone NFC Read Distance | Tiny NFC Tags

iPhone NFC read distance depends on the size of the NFC tag antenna. Second the type of NFC chip affects the NFC read distance from the iPhone. Third, NFC reader power and design affect read distance, these are fixed based on iPhone model. Additionally, See this post for examples of iPhone NFC tag read range.

Here see the read range of two tiny NFC tag chips types (NTAG213, SLIX) on iPhone 15 Pro Max,  14, 13 Pro.

  • iPhone 15 Pro Max – NTAG213 ~ 2mm, , SLIX ~ 9mm
  • iPhone 14 – NTAG213 ~ 2mm, SLIX ~ 9mm
  • iPhone 13 Pro – NTAG213 ~ 2mm, SLIX ~ 9mm

Location Of iPhone NFC Reader Antenna

First the iPhone’s NFC reader interface is at the top-back-edge of the iPhone, with best read point about the center. Next, this location is typically more convenient than Android phone’s NFC reader on the backside of the phone. Additionally you’re able to hold the iPhone conveniently in your hand while reading NFC tags.

How Does iPhone Case Affect NFC Reading?

How NFC reading is affected by the iPhone case is mainly due to the case thickness at the NFC interface. First virtually every iPhone case is made of plastic, the material typically does not affect NFC reading. Next, Thickness of a common type of clear iPhone case is about 1.5mm. Additionally it’s important to note iPhone case thickness varies depending on iPhone and case design. See the iPhone 13 Pro case below, the main case back thickness is 1.5mm, but the thickness near the camera lens is 2.5mm. Depending on the iPhone case, and NFC chip type used, the tag may only be readable with the case removed.

First we test tiny 4.5mm NTAG213 tag attached to a rubber type object over 5mm thick. Second we test tiny 4.5mm SLIX tag attached to the same.

The NTAG213 tag (ISO14443 type chip) fails to read with any iPhone, with our without a thin iPhone case. Yet the SLIX (ISO15693 type chip) reads from iPhone 15, 14, 13 while in the iPhone case. Use the proper NFC chip design to have an iPhone read tiny NFC tag even in the iPhone case.
