Here are five cards from five Genghis product pages.

Amazon: works in the United States only. A 50 USD card costs $50.20.
ASOS: works in the United States only. A 25 USD card costs $25.00.
Birkenstock UAE: works in the United Arab Emirates only. A 100 AED card costs $27.45.
Birkenstock India: works in India only. A 2,000 INR card costs $21.32.
AJIO: works in India only. A 2,000 INR card costs $22.69.

The prices are the least interesting part. Look at the country in each line. Every card names one. The pages repeat it in a sentence: "Each card redeems only in its own country."

What those lines say

A gift card has a country, not a currency. The same brand can be sold as several different cards. Birkenstock has a card for the UAE priced in dirhams and a card for India priced in rupees. They are separate products with separate balances. The UAE page lists India, Bahrain, Kuwait, Oman, Qatar and Saudi Arabia as other editions. The Amazon US page lists 17 countries, from Australia and Canada to Turkey and the United Kingdom. The ASOS US page lists Australia, France, Germany, Italy, the Netherlands and the United Kingdom.

Your wallet has no country. The store account you redeem on does.

What goes wrong when the country does not match

Say someone in the UAE sees an Amazon card at $50.20 and pays for it with USDT. The code arrives and is valid. They sign in on their own Amazon site and the code is rejected, because the card was made for amazon.com in the United States. Nothing broke. The country line was visible before the payment.

That is why the refund rule matters. The product pages say digital codes cannot be refunded once delivered unless the code is invalid. A code that works only in another country is a valid code, so you should not count on getting the money back.

Where to read the country line

Three places carry it: under the product name, in the "Same card for another country" row and in the FAQ answer to "Where can I use it?". The ASOS page puts it plainly: this card is for the US region, check it matches where you will use it.

On the Genghis fashion and apparel gift cards page there is a filter for products in your own country. When I opened it the list showed only India cards, although the ASOS US and Birkenstock UAE pages exist. I read that as the page filtering by country, so check which list you are looking at before you pick. Then open the card itself. On the Amazon US page the redeem steps are short: sign in on amazon.com, open Gift Cards, choose Redeem a Gift Card and enter the code. The balance stays in your account and applies at your next checkout.

What if the card is a gift?

Then the country of the person who will use it decides, not yours. Someone paying from a wallet in one country can buy a card for a friend who shops in another. The friend needs a card made for the store in their own country. The "Same card for another country" row on the product page lists the other editions. Pick the edition that matches the recipient, then check the country line once more.

Face value and price are two different numbers

The face value is printed in the card's own currency: dirhams, rupees or dollars. The price you pay is shown in crypto. The pages show both before you pay. The catalog also says you see the exact amount before you pay. The pages do not say which exchange rate sits behind the conversion, so I will not guess at one. What you can compare is the face value you receive against the price you are shown, on each card, for the day you buy.

Is a small first card worth it?

Yes. The ASOS card starts at 5 USD for $5.00 and has 20 values. The UAE Birkenstock page starts at 50 AED for $13.72. A small first purchase is where you find the mistakes cheaply: a wrong country, a typo in the code, an account that asks for something you did not expect. A $5 lesson beats a $50 one.

Cards for the same brand can differ in more than the country. The UAE Birkenstock page lists 21 values and the India page lists 8. The ASOS US page lists 20. Each edition has its own range, so a value you saw on one page may not exist on the next. Pick the edition first and the amount second.

One more habit helps. Read the country line twice, once on the list and once on the product page. They come from the same data. The second read catches a mis-click.

The refund line is the last thing worth knowing. Digital codes cannot be refunded once delivered unless the code is invalid. If a code is rejected, send the order number through the Help Center.
