The technology that makes a proximity card work includes an antenna
and electronic Proximity Card chip. Both of these are embedded into the
card when it is manufactured. All proximity card brands (e.g., HID,
ValuProx, Indala, Kantech, Keri, Casi, AWID, etc.) use a similar
technology where elements are embedded inside the card.
Why Prox Cards Fail
There are three primary reasons for proximity card failure:
Damage to the antenna or damage to the bond between the chip and the antenna will destroy the card.
Exposing the card to electro static discharge (ESD) can damage the integrated circuit.
Strong magnetic fields can wipe out the programming on the card’s chip.

are intended to be used strictly for access control and identification
purposes. When cards fail, it’s frequently the result of unintentional
abuse by the card holder. Below is a list of common actions that will
damage a prox card:
Machine washing the card by accident when it’s forgotten in a pocket of a shirt or pair of pants
Exposing the card to extreme heat (direct sunlight on the dash of your car, clothes dryer or iron)
Punching a hole or slot in a non-designated area which can damage the internal antenna or electronic chip
Using the card as an ice scrapper for the windows of your vehicle
Bending, twisting, sitting on, or crimping the card
Exposing the card to chemicals including organic solvents, thinners, mineral spirits, alcohol, isopropyl, ethanol, or methyl.
What You Can Do to Protect Prox Cards
Physically protecting your proximity card is a vital preventative
measure against damage or abuse. To prevent damage, the very best way to
do this is by using an ID badge holder. Not only are badge holders an
easy way to prolong the life of your prox card; they’re also affordable
and come in a variety of choices for use in virtually any environment.
Look
for features in a badge holder that will most effectively suit your
requirements. Common options include flexible vinyl holders for light
duty use and a simple method of protection. They can have features like a
sealable top similar to a sandwich bag, UV protection, or anti-print
transfer technologies to keep the actual image from wearing off on the
holder. They allow the cards to be protected but still visible.
Your
ideal solution against physical damage would be a ridged holder. This
type of prox card holder is made of hard, long-lasting plastic and
well-designed to take more abuse. They come in a number of styles,
including
styles that lock cards into the holders
a slotted version to easily remove cards
a multi-sided model to hold different card types (e.g., thicker clam shell prox cards)
