How to tell the type of card you have?

Different cards correspond to different devices and empty cards. You need to distinguish your card type before purchasing, and be sure to distinguish between them. Don't choose the wrong one or buy the wrong card, which will cause it to become unusable. The following methods can identify most card types.


Method 1: Distinguish the shape of the card antenna through light perspective

In a dark light environment, turn on the flashlight function of the mobile phone and look through the other side of the card. You can see the shape of the antenna inside the card. The circle is the ID card, and the rounded rectangle is the IC card. If it has both, it is a dual-band card.

The above method is only applicable to standard size [cards the same size as bank cards]. This method cannot be used for small cards. If it is a hotel room card, the coil will be round. It is not an ID card, but a special encrypted card. It cannot be used.


Method 2: Distinguish by card number

As shown in the picture below, if the card has a 10-digit or 18-digit number starting with 00, it is usually more

for ID card

Keychains that look like the picture below, if they don’t have numbers, are usually  IC keychains.

Method 3: Identify through the NFC function of the Android phone

Android phones with NFC function will sense 'IC' type cards and can be used to

Distinguish between IC' and '1D' cards; you can download the tool 'MIFARE CLASSIC-TOOL' in the Android App Store to check the specific type and encryption of the IC card, but this card does not support mobile phone copying.
