Is Your Aadhaar Card RFID? Which Indian Cards Use RFID/NFC

What UIDAI says is on the Aadhaar PVC card

On its Order Aadhaar PVC Card page, UIDAI answers the question "What are the security features of Aadhaar PVC Card?" with this list:

• Tamper proof QR Code
• Micro text
• Ghost image
• Issue Date & Print Date
• Guilloche Pattern
• Embossed Aadhaar Logo

Every item on that list is printed or embossed. The one machine-readable feature is the QR code, which the same page describes as giving instant validation through scanning: it is read by a camera, not by a radio reader. The page also says that the Aadhaar letter, the Aadhaar PVC card and e-Aadhaar are different forms of Aadhaar that are equally valid and acceptable, and none of the three relies on a chip.

So an RFID reader or an NFC phone held against an Aadhaar PVC card has nothing to detect. If your phone reports an NFC tag when you touch your wallet, it has found another card in it, most likely a bank or metro card.

Which everyday cards and tags do use RFID or NFC

The sections below explain each row, and our NFC vs RFID guide explains how 13.56 MHz NFC relates to the wider family of RFID frequencies.

The e-passport: a chip by design

Passport Seva, run by the Ministry of External Affairs, describes the ePassport as a combined paper and electronic passport with a Radio Frequency Identification (RFID) chip and an antenna embedded as an inlay, holding the holder's personal particulars and biometric information. You can recognise one by a small gold-coloured symbol printed below the front cover. The data is printed in the booklet and also digitally signed in the chip, which lets immigration officials anywhere check that it has not been altered; Passport Seva names Public Key Infrastructure as the technology behind that.

Existing passports stay valid until they expire, and each passport office switches to ePassports as it is enabled.

Can someone read it in a crowd? Our guide to whether RFID blocking is necessary goes through the published research on range and access control.

Contactless bank cards: NFC with an RBI limit

A debit or credit card with the contactless symbol carries an NFC chip. The Reserve Bank of India's circular RBI/2020-21/71 of 4 December 2020 raised the limit for contactless card payments without an additional factor of authentication, such as a PIN, to 5,000 rupees per transaction, from 1 January 2021.

The RBI's FAQ on card transactions adds that this applies to contactless payments at shops, not ATM transactions, and only where the EMV standards are followed. Above that amount, the PIN or another factor is still needed. The circular also keeps your choice of contact or contactless mode, and refers to the RBI's January 2020 instructions under which you can switch contactless transactions on or off, or set a limit, with your bank.

Metro cards, office cards and hostel cards

Metro smart cards and tokens are contactless HF fare media: our guide to metro RFID tokens and smart cards reads an actual metro specification line by line. Office, hostel and campus cards are more varied. Many are 125 kHz proximity cards, which carry little protection and can be copied with brief access; others are 13.56 MHz cards, some with encryption. Our RFID data security guide explains the difference, and organisations choosing new cards can compare them in our RFID card buyer's guide.

FASTag

Your FASTag is a passive UHF RFID tag made to be read from a distance at toll and parking lanes; our FASTag and vehicle RFID guide explains how it works.

Other "Aadhaars": Pashu Aadhaar and Battery Pack Aadhaar

Two newer identity schemes borrow the Aadhaar name, and neither of them is an RFID card either.

• Pashu Aadhaar, for livestock. According to a PIB research note of January 2026, a unique 12-digit bar-coded tag ID in the form of an ear tag is being issued to all livestock animals under the National Digital Livestock Mission, and this code is named Pashu Aadhar. It acts as the key for recording vaccination, breeding and treatment. The same note mentions RFID bull tags at semen stations, which shows where RFID does appear in the dairy system. Where a scheme or cooperative specifies an electronic animal tag, our livestock ear tag guide covers the 134.2 kHz standard, and the tags themselves are in animal and pet RFID tags.
• Battery Pack Aadhaar, for EV batteries. MoRTH's draft guideline gives each battery pack an alphanumeric ID marked as text and a QR code; as our Battery Pack Aadhaar guide explains, the draft does not mandate RFID, although manufacturers may add it on the production line.

How to check a card yourself

1. Use an NFC phone. Turn NFC on and hold the card flat against the back of the phone. A bank, metro or 13.56 MHz office card will usually make the phone react; an Aadhaar PVC card will not.
2. Remember what a phone cannot see. A phone reads only 13.56 MHz. It cannot detect 125 kHz proximity cards or UHF tags such as a FASTag, so "nothing happened" does not always mean "no chip".
3. For bulk checks, use a desk reader. Offices enrolling staff cards use a USB reader: the HRD20 (₹2,000 + GST) reads 13.56 MHz cards at 5–10 cm, and the IDTS-LFPPR (₹1,500 + GST) reads 125 kHz cards at 5–8 cm.

If you want a sleeve for the cards that do have chips, read our RFID blocking guide first: for most people the bank's own controls do more.
