For caning the recipient is bent over a wooden frame and their ankles and wrists are restrained. Padding is put over the lower back (to protect the kidneys) and below the buttocks (to protect the genitals) so only the butt cheeks are exposed.
“The Singapore Criminal Procedure Code lays down that 24 strokes is the maximum that can be ordered at any one trial. The strokes must all be inflicted on the same occasion, and not in instalments. The Singapore Prison cane is made of rattan. Unlike bamboo, this is very flexible when wet. In some pictures the soaked rattan appears to be so bendy that it may be understandable that some observers are said to have mistakenly thought the implements were actually leather whips. The size and dimensions of the cane are prescribed by regulation. For adult men it is 1.2 metres long and 1.3cm thick, thus about as long as a broom handle and as thick as a man's little finger. A smaller cane, the "light rattan", is used for boys under 16”.
“There are dozens of offences for which a man might be given the cane in Singapore - from serious violent crimes to some non-violent offences that seem relatively minor in the West but are regarded as serious in Singapore, a highly authoritarian state where the importation and sale of chewing gum is an offence (though not a caneable one) and where people can be prosecuted and fined significant sums for dropping litter, smoking in public places, or failing to flush a public toilet after use."
"Caning in Singapore is mandatory for over 40 different offences. These range from serious crime, such as rape, robbery, or drug-trafficking, to lesser offences - possession of offensive weapons (such as a knife, dagger or sword), vandalism (including spray painting or a second offence of affixing a poster to a wall), or the sale, transport, delivery, or import of fireworks.
Men who enter Singapore illegally or who overstay their visas by more than 90 days automatically receive a minimum of 3 strokes of the cane. In some cases a mandatory minimum number of strokes is required -- up to 15 for certain offences."
"Caning is optional for many further offences including rioting, extortion, living off the earnings of prostitution, manslaughter, and causing hurt. It has also been introduced for a third offence for certain road traffic offences, though there are few reports of this being applied in practice.
Since the 1990s, moreover, the highest courts have been more inclined to impose sentences of caning even where it is not mandatory. Examples are in cases of rape; "road bullying" where grievous hurt results; hiring of persons to assault another; and molesting women.
The Chief Justice has stated that in cases of "outraging the modesty of a woman" (indecent assault), all courts are expected to order a minimum of 9 months' imprisonment and three strokes of the cane if the offence involves touching the woman's private parts.
In a few instances, Singapore legislation requires that male employees be caned for offences committed by a company. The Dangerous Fireworks Act requires that a manager, director or owner of a company which deliberately or negligently imports, delivers or sells dangerous fireworks must be caned.” (Given the Enschede fireworks disaster I can understand their logic here). Prisoners can also be given up to 12 strokes for misbehaving. Those int eh armed forces may also be caned for disciplinary reasons.
“A former employee at the Drug Rehabilitation Unit in Changi prison said six strokes were given for drugs in the urine or for homosexuality (illegal in Singapore), and three for fighting.
The Singapore High Court is empowered to order the cane for boys under 16 although this is rare. In July 1999 the High Court ordered three 15-year-olds to be caned for offences committed while one of them was still only 14 (a rape trial). Three months later the Court went even further, sentencing a boy still only 14 to five years in jail and ten strokes of the cane for kicking and robbing an elderly man. Ten strokes is the maximum for boys under 16 and the caning in such cases is applied with a "light rattan".
