How to compare the credit cards you already own

Published 2026-10-09

If you already have two credit cards, you do not need a new application to make a better choice about the next purchase. Pick a purchase you actually make. For each card, check whether that transaction qualifies for a reward, what could exclude it, whether a cap has already been reached, and how you would use the reward. Keep fees and renewal conditions in a separate column. If a term is unclear, write unknown. Unknown does not mean zero, and a headline rate alone does not identify a winner.

Start with one purchase

Write down the merchant or spending category and the way you would pay. For example, an online purchase from Amazon and a rent payment are two different questions. A card may treat them differently. You need only enough detail to locate the applicable terms. Do not put a card number, PIN, statement or personal account details into a public comparison.

Now make two card columns, one for each card you hold:

Copy these questions into your own note. This table does not save answers. On a phone, swipe sideways to see both cards.
Question	Card A	Card B
What is the exact card variant?
Does this purchase qualify?	Yes / no / unknown	Yes / no / unknown
Which exclusion or merchant condition matters?
Is there a cap or a minimum redemption amount?
How and where can you use the reward?
What fee or renewal condition matters to keeping the card?
Which issuer document and date support each answer?

Do not turn the table into a points score. It is a way to expose a missing answer before you move spending to a card.

Want to start with the card details? SwipeSage is available for Android on Google Play. Look for a card you hold, then use the issuer’s current documents to complete the rows above. The app is a starting point for inspection; this worksheet is not a promise that the app performs every check for you.

Read costs and rewards in the right places

The issuer’s Most Important Terms and Conditions, or MITC, is where you check fees, charges, interest and the conditions for keeping or renewing a card. The card-specific terms and conditions are where you check what earns rewards, exclusions, caps and redemption rules. Read the document for the exact card variant. A product page can help you find those documents, but its headline is not enough to settle the comparison. See how SwipeSage checks sources.

If you are choosing which card to use for the next purchase, the joining fee you have already paid will not change with that purchase. A renewal fee can matter when deciding whether to keep a card. Keep that ownership decision separate from whether a particular transaction earns a reward. The amount shown in a general fee table may also differ from your personal offer, so check the terms communicated to you and your statement. ICICI’s MITC explicitly says fees can vary by member and offer.

A worked comparison: HDFC Millennia and Amazon Pay ICICI

Suppose you already hold both cards and you are about to buy an item on Amazon. HDFC’s Millennia terms, published 20 July 2026, list Amazon among the merchants in a higher cashback tier. The same document says qualification depends on merchant or terminal identifiers supplied by partners and has a cap. An Amazon logo on the checkout screen does not settle those conditions.

ICICI’s Amazon Pay card terms, last updated 13 January 2026, distinguish the amazon.in reward tier by Prime membership and exclude some transactions from that headline tier. They also list transaction categories that earn no reward points. Before comparing the two cards, ask whether your exact purchase qualifies on each, whether you have reached a cap, and whether the reward form is useful to you. HDFC describes CashPoints that can be redeemed against a card statement; ICICI describes rewards credited as Amazon Pay balance. Those are different ways to use a reward, not interchangeable cash in your bank account.

Now change the example to rent. HDFC’s Millennia reward table excludes rent payments from its other-spends tier. ICICI’s Amazon Pay card terms also say rent transactions do not earn reward points. That is enough to reject a simple “one card earns on everything else” argument for this purchase. It is not enough to say which payment method you should use: check any applicable payment charges in the issuer’s current MITC and your own terms before making that decision. The current HDFC MITC and ICICI MITC are the fee starting points, not reward sources.

This example has no universal winner. A different purchase, a different offer, a cap already used this month, or a reward you cannot redeem conveniently can change the answer. The HDFC Millennia review and Amazon Pay ICICI review explain each card in more detail, but your current issuer terms and own account conditions still govern your choice.

Decide what you know, then stop

For the purchase in front of you, circle each answer that is supported by the exact issuer document. If a fee, exclusion or eligibility condition is missing, leave the row open and check with the issuer. Do not fill it with a marketing headline, a general card catalogue, or a rate quoted for a different card. If both cards fail the question you care about, waiting or using another payment option may be more sensible than applying for another card just to complete a comparison.

Source note: Issuer documents were retrieved and checked on 9 October 2026 IST. The HDFC Millennia card-specific PDF identifies the card and shows a 20 July 2026 first-page publication date; later pages still bear a 25 April 2025 heading and include conflicting wording about gift cards and vouchers. This article does not assign those transactions a reward rate. The ICICI Amazon Pay card-specific PDF identifies the card and says it was last updated 13 January 2026. The ICICI MITC says last updated 2 August 2026; HDFC’s MITC says updated 8 October 2026, version 4.13. Issuers can replace files at the same URL.
