Personalised wristbands are a branded band of material (Tyvek, PVC vinyl or fabric) which is worn around the wrist, and quite hard to remove, and reattach. They are very common at ticketed events and promotions.
Tyvek is a very strong, paperlike material, made from flash spun polyethylene fibres, bonded together with heat [Source Wikipedia}. Tyvek wristbands are printed either one colour, black, or full colour and one end section is pre cut, and prepared with a strong self-adhesive. Once attached to a person's arm, it will not come off, without a very hard tug, or by being cut off with scissors. Once detached, the tyvek wristband can't be reworn, without it being obvious that it is a spoiled wristband. [Choice of Tyvek Wristband colours and artwork template]
When a more durable wristband is required (for a weekend festival for instance), then vinyl wristbands are often utilised. Vinyl wristbands tend to be branded with one colour screen printed onto the PVC, black, white, gold are typical examples of print onto these bands.

The creme de la creme of non-transferable security wristbands are the fabric wristbands, which have fast become a must-have on the festival and nightclub scene.

Fabric wristbands are the most comfortable to wear and you can guarantee that you're wristband will stay on the owner for weeks after your event.
"We use printed tyvek wristbands for our contestants and events team at the annual Worthing International Birdman Rally. Depending on the persons role for the Birdman weekend, they are assigned a certain colour band. Our flyers receive a second band, once they have attended their safety briefing, and no flyer's without that second wristband on" - Jim Cunliffe - Worthing Birdman Events Team
If a patron is attempting to use a spoilt wristband, it is usually pretty obvious. They will try to keep full visibility from you, by keeping their arm down or tight to their body. The simple security test for a wristband is to ask for the patron to put their arm forward, then hook a finger underneath the band, and yank it towards you. If the wristband is spoilt, it will come away in your hand.
Ask the patron to pull up their sleeve and take the arm towards you. keeping two fingers to the skin, wrap the band around the wrist, and secure. The two fingers will give enough space for movement, but tight enough for the patron to not be able to remove and transfer the band to a friend.
