VTAP25 Compliance

The VTAP25 module has been certified for Apple VAS, Apple ECP2/Access and Google Smart Tap, CE, UKCA, FCC, ISED. The integrator must usually perform testing of the final product to ensure the compliance is maintained.

Dot Origin can provide support throughout the compliance process. Our engineers have extensive experience of compliance testing and approval processes. Please contact us at vtap‑support@dotorigin.com at an early stage of your project to discuss the options and recommended steps involved.

CE / UKCA

The VTAP25 with its VTAP25DEV reference antenna has been tested for CE (RED/safety) / UKCA compliance. However, the host product must be tested for all the relevant directives under CE / UKCA.

FCC/ISED module integration instructions

The VTAP25 reader module with its VTAP25DEV reference antenna has been tested for modular device approval under FCC rules Part 15 and ISED RSS‑210, with a reference host board including a 40x40mm NFC antenna and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause undesired operation.

These instructions must be followed to maintain the FCC/ISED approval for the VTAP25 reader module, when it is integrated into a host system.

CAUTION: Changes or modifications made to the VTA25 reader module, that have not been expressly approved by Dot Origin Ltd could void the user's authority to operate the equipment.

Applicable FCC/ISED rules

The VTAP25 reader module operates at 13.56MHz and is therefore subject to FCC/ISED rules for radio frequency devices.

Specific operational use conditions

The VTAP25 reader module must be stored and operated under the following conditions:

Ambient temperature -40 to +85°C (-40 to 185°F)
Humidity 0 to 95% RH non-condensing
Pressure 86-106kPa

RF exposure considerations

Screened cable should be used, wherever possible, to connect VTAP25 reader module to other devices, to avoid interference from other equipment.

The end-user manual for the host equipment, that contains a VTAP25 module, must clearly indicate the operating conditions to be observed, so that the user remains in compliance with current FCC/ISED RF exposure guidelines.

Antennas

The VTAP25 reader module has been tested with a VTAP25DEV reference host board including a 40x40mm NFC antenna. There are no alternative antennas approved for use. When an external antenna is attached, the new arrangement would require a new FCC/ISED approval.

Label and compliance information

The integrator must attach a label to the new equipment, hosting the VTAP25 reader module, which states 'Contains FCC ID: 2A282‑VTAP25' , in accordance with enclosed module ID for FCC approval and 'Contains IC: 30458‑VTAP25' for ISED approval.

Information on test modes

The following test modes are recommended to achieve states of maximum emission levels or susceptibility in the VTAP25 reader modules:

VTAP25 reader module powered on. Communicating with PC over USB. Continuously reading tag.
VTAP25 reader module powered on and tag present, but not communicating with external device.

Additional testing requirements

The VTAP25 reader module is only FCC/ISED authorised for use in compliance with the specific FCC/ISED transmitter rules listed on the grant. The integrator is responsible for compliance to any other FCC/ISED rules that apply to the host, which are not covered by the modular transmitter grant of certification.

The final host product, with the VTAP25 module installed, will still require Part 15 Subpart B compliance testing with your NFC antenna, and to evaluate transmission effects when the VTAP25 reader module and host equipment operate at the same time. Typically, Dot Origin can obtain a permissive change on the VTAP25 original modular approval. This is faster and less expensive than a new application. In this case, the integrator must ensure that all the guidelines in this document are followed. We recommend integrators refer to further advice from the FCC OET Knowledge Base, such as 996369 D04 Module Integration Guide v02.

Apple VAS and ECP2

The VTAP25 is certified for Apple VAS and ECP2/Access.

There are some steps required in order to maintain Apple VAS(ECP1) and/or ECP2/Access compliance.

When you request an NFC entitlement and/or permission for an Apple Access deployment we recommend that you inform Apple that a Dot Origin VTAP OEM board or module has been used in your finished product. Apple are aware that our products are available both in finished form and as OEM modules.

For VAS applications Apple reserves the right to review the final form factor of the reader, to ensure that satisfactory performance and user experience is maintained.
For ECP2 applications it is essential that the new equipment hosting a VTAP reader board or module is tested and certified against Apple Access specifications. This includes ensuring that the read range meets their minimum distance requirements (40mm at various presentation angles, in Express and CDCVM modes) and that the reader is tested against all the different categories of iPhone and Apple Watch, as required by Apple. Apple may also require on-site functional testing as part of the end‑to‑end certification of an Apple Access deployment, which is usually conducted by the Credential Manager.

Some of these certification tests do require the user feedback from the VTAP reader for a successful read, either visually or by sound. The buzzer on a VTAP reader produces a long beep, sufficient to pass this test.

In both cases, our engineering team can advise and assist on certification issues, which could include taking a product through formal certification, if required.

Google Smart Tap

The VTAP25 is certified for Google Smart Tap.

The integrator should test the final product with NFC passes in Google Wallet of different Android phones prior to rolling out, to ensure the compliance is maintained.

Recommendations for EMC

To ensure that the final product is compliant with various standards for radiated and conducted emissions, please follow the guidelines in this document relating to USB and antenna track placement and external connections.
