2. Which devices can utilize KEYRING PiGET Payment?

As of now, KEYRING PiGET Payment is exclusively available on Android mobile devices, as it requires the NFC function to facilitate the payment process.

Although KEYRING PiGET can be used on iOS devices, the KEYRING PiGET Payment feature, unfortunately, is not available for iOS users. Apple's strict policies restrict the use of alternative payment methods, such as KEYRING PiGET Payment, on iOS devices.

3. Does KEYRING PiGET Payment accept all types of cryptocurrencies?

No, it doesn't.

KEYRING PiGET Payment currently only accepts two types of tokens: ERC-20 and ERC-1155.

ERC-20

ERC-20 is one of the widely used standards for tokens in the crypto realm. So, chances are, the tokens you possess can likely be utilized for KEYRING PiGET Payment without any issues.

Moreover, you have the flexibility to exchange or convert your tokens into ERC-20 tokens if needed.

ERC-1155

As for ERC-1155, it's a prominent standard for NFTs (Non-Fungible Tokens).

While KEYRING PiGET Payment does accept NFTs as a valid form of payment, the specific NFTs eligible for payment are determined by the shop owners or sellers.

Essentially, sellers have the option to issue vouchers or payment tickets in the form of NFTs using the ERC-1155 standard. Buyers can then utilize these NFTs to make their purchases.

Supported chains

Currently, KEYRING PiGET Payment supports cryptocurrency payments across four chains:

• Ethereum.

• Binance Smart Chain (BNB).

• Polygon.

• Avalanche.

• Optimism.

4. How to use KEYRING PiGET Payment?

To proceed with the payment, the merchant needs to access the appropriate payment page on PiGET Payment corresponding to the type of token they intend to use for the transaction.

There will be two separate payment pages for ERC-20 and ERC-1155 tokens.

• ERC-1155:

For ERC-1155 tokens, or simply put, NFT-1155, finding their contract addresses isn't difficult at all, thanks to the KEYRING NFT Viewer.

6. What is PiGET Payment used for?

PiGET Payment functions as a solution empowering merchant to embrace cryptocurrency, facilitating seamless transactions.

This innovation allows merchants to transition from traditional fiat exchanges to accepting cryptocurrencies, notably ERC-20 tokens and ERC-1155 tokens.

For instance:

• ERC-20 Tokens can be utilized for payment of goods or services.

• ERC-1155 tokens could represent coupons issued by establishments, allowing customers to redeem these coupons for discounts or benefits at the respective stores.

7. Why do I see numbers displayed upside-down when receiving payments with ERC-20?

This design choice allows the buyer to easily view the amount they need to pay.

Typically, buyers are facing the seller during the payment process, so this orientation facilitates their visibility of the payment amount.

8. What happens if the buyers don't have the ERC-20 token I specified for receiving payment?

You're not limited to a single token choice. If your buyers don't possess the designated token for payment, you have the flexibility to switch the token you wish to receive, as long as it is ERC-20 token.

Simply by adjusting the Token contract address, you can adapt your preferred payment currency to suit the availability of your buyers' tokens.
