How to correctly implement form autofill with Google Pay tips?

Question

Google

Given: there is a form for the web, when filling out the form from a mobile, namely entering a credit card number, a hint should pop up that you can connect the google pay payment (as on the layout).

I tried to implement with autocomplete attributes:

<form>
    <label for="frmCCNum">Card Number</label>
<input type="tel" name="cardnumber" id="frmCCNum" required autocomplete="cc-number">
  </form>

and according to this article: 4xpro.ru/profblog/google-pay-2
but nothing happened. Are there any tutorials or ready-made solutions on how to accomplish this task?

Answer 1

As far as I understand, the data on the card is automatically offered (if there are correct metas in the markup), if any: Autocomplete Google Pay forms .
Therefore, most likely, if there is no data on the card in the account, then there will be no offers to pay.
