The characteristics specified include:
- Physical dimensions
- Resistance to bending, chemicals, temperature, and humidity
The standard includes test methods for resistance to heat.
The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000.
|mm x mm||inch x inch|
|ID-1||85.6 x 53.98||3.4 x 2.1||Most banking cards and ID cards|
|ID-2||105 x 74||4.1 x 2.9||Romanian and other ID cards. Visas.|
|ID-3||125 x 88||4.9 x 3.5||United States government ID cards|
|ID-000||25 x 15||1 x 0.6||SIM cards|
All card sizes have a thickness of 0.76 millimetres (1⁄32 in).
The standard defines both metric and imperial measurements, noting that:
Numeric values in the SI and/or Imperial measurement system [...] may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should not be intermixed or reconverted. The original design was made using the Imperial measurement system.
The ID-1 format specifies a size of 85.60 by 53.98 millimetres (3+3⁄8 in × 2+1⁄8 in) and rounded corners with a radius of 2.88–3.48 mm (about 1⁄8 in). It is commonly used for payment cards (ATM cards, credit cards, debit cards, etc.). Today it is also used for driving licences and personal identity cards in many countries, automated fare collection system cards for public transport, in retail loyalty cards, and even (particularly for aircrew).
The ID-2 format specifies a size of 105 by 74 millimetres (4+1⁄8 in × 2+15⁄16 in). This size is the A7 format. The ID-2 format is used, for example, for visas. It is used for the Romanian identity card, and was also used by the German identity card issued until October 2010 and French up to july 2021. German ID cards (since November 2010) and French ID cards (since August 2021) are issued in the ID-1 format more widely used in Europe for national ID cards. ID-2 was previously also used for Finnish and Swedish drivers' licences before those changed to the ID-1 format.
ID-000 specifies a size of 25 by 15 millimetres (1 in × 9⁄16 in), with one corner slightly (3 mm or 1⁄8 in) bevelled. The ID-000 size was first defined by ENV 1375–1, Identification card systems — Intersector integrated circuit(s) card additional formats — Part 1: ID-000 card size and physical characteristics.
ID-000 size card as part of ID-1 size card
An "informative" (i.e. non-mandatory) annex describes how an ID-000 sized card may be included in an ID-1 size card for processing (e.g. in an ID-1 reader), but with "relief areas around the perimeter of the ID-000 size card to allow it to be removed from the ID-1 size card without punching tools". An ID-1 size card containing an ID-000 size card is denoted as ID-1/000.
The standard specifies requirements for such physical characteristics as:
- Bending stiffness
- Resistance to chemicals
- Card dimensional stability and warpage with temperature and humidity
- Resistance to deterioration from exposure to light and heat
- ISO/IEC 7811 defines traditional techniques for recording data on ID-1 identification cards, namely embossed characters and several different magnetic recording formats.
- ISO/IEC 7816 defines ID-1 identification cards with an embedded chip (smartcard) and contact surfaces for power, clock, reset and serial-data signals.
