So now we see that the Swedes are going large with their implantable chips which allow them to carry out certain kinds of transactions without using plastic.

Thousands of people in Sweden get microchip implants for a new way of life


It’s the size of a grain of rice but could hold the key to many aspects of your life.

A tiny microchip inserted under the skin can replace the need to carry keys, credit cards and train tickets.

That might sound like an Orwellian nightmare to some but in Sweden it is a welcome reality for a growing number who favour convenience over concerns of potential personal data violations.

The small implants were first used in 2015 in Sweden – initially confidentially – and several other countries.

Swedes have gone on to be very active in microchipping, with scant debate about issues surrounding its use, in a country keen on new technology and where the sharing of personal information is held up as a sign of a transparent society.

Sweden’s SJ national railway company has won over some 130 users to its microchip reservation service in a year.

Conductors scan passengers’ hands after they book tickets online and register them on their chip. Sweden has a track record on the sharing of personal information, which may have helped ease the microchip’s acceptance among the Nordic country’s 10 million-strong population.

My question is:

How to read the information, then what information is stored in them?

How do these microchips work? Are they merely RFID units that store a single personal ID number? Or is it something more complex, like a SIM card or Smartcard with some other kind of registration?

As I know they implant these NFC tag ICs:

NTAG213_215_216: NFC Forum Type 2 Tag compliant IC with 144/504/888 bytes user memory (nxp.com)



  • Contactless transmission of data and supply energy

  • Operating frequency of 13.56 MHz

  • Data transfer of 106 kbit/s

  • Data integrity of 16-bit CRC, parity, bit coding, bit counting

  • Operating distance up to 100 mm (depending on various parameters as e.g. field strength and antenna geometry)

  • 7-byte serial number (cascade level 2 according to ISO/IEC 14443-3)

  • UID ASCII mirror for automatic serialization of NDEF messages

  • Automatic NFC counter triggered at read command

  • NFC counter ASCII mirror for automatic adding the NFC counter value to the NDEF message

  • ECC based originality signature

  • Fast read command

  • True anticollision


  • 180, 540 or 924 bytes organized in 45, 135 or 231 pages with 4 bytes per page

  • 144, 504 or 888 bytes freely available user Read/Write area (36, 126 or 222 pages)

  • 4 bytes initialized capability container with one time programmable access bits

  • Field programmable read-only locking function per page for the first 16 pages

  • Field programmable read-only locking function above the first 16 pages per double page for NTAG213 or per 16 pages for NTAG215 and NTAG216

  • Configurable password protection with optional limit of unsuccessful attempts

  • Anti-tearing support for capability container (CC) and lock bits

  • ECC supported originality check

  • Data retention time of 10 years

  • Write endurance 100,000 cycles

  • Excellent answer. For the first part of the question - is it simple or more complex. Clearly it is not just simple. And with this small amount of memory they clearly are not storing full biometrics. I wonder what information is stored in the microchips...?
