Source-derived summary

ISO/IEC 7810 Identification cards — Physical characteristics is an international standard that defines the physical characteristics for identification cards.

The characteristics specified include:

Physical dimensions

Resistance to bending, chemicals, temperature, and humidity

Toxicity

The standard includes test methods for resistance to heat.

Card sizes

The standard defines four card sizes: ID-1, ID-2, ID-3 and ID-000.

All card sizes have a thickness of 760±80 μm, i.e. minimum 0.68 millimetres (0.027 in) and maximum 0.84 millimetres (0.033 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.

ID-1

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). This format is also referred to as CR-80 and, for travel documents, TD1.

Editorial summary

Begin with the source’s own compact description: “ISO/IEC 7810” is standard for ID cards. The dossier treats that line as a proposition to test through Standard and cards, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 179-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Standard and cards is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “standard for ID cards” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 29, 2026. The linked authority identifier is Q1193705. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
